440,758 Common Shares of Beneficial Interest

     This prospectus relates to the possible issuance, from time to time, of up to 440,758 common shares of beneficial interest, no par value, to the holders of limited partnership units, or LP Units, of our operating partnership, IRET PROPERTIES, a North Dakota Limited Partnership, or IRET Properties. Our common shares are the functional equivalent of common stock, having the rights and preferences normally associated with common stock. We may issue the common shares covered by this prospectus to the holders of LP Units to the extent that they redeem their LP Units of IRET Properties and we elect to issue common shares in connection with such redemption. We may also elect to pay cash for redeemed LP Units in lieu of issuing common shares. We will not receive any proceeds from any common shares issued in exchange for the redemption of LP Units. The persons receiving common shares covered by this prospectus upon redemption of LP Units are referred to herein individually as a “selling shareholder,” and collectively as the “selling shareholders.”

     This prospectus also relates to the offer and resale, from time to time, by the selling shareholders of the common shares covered by this prospectus. We will not receive any proceeds from the possible resale of common shares by any selling shareholder.

     We are registering the common shares covered by this prospectus as required under the Agreement of Limited Partnership of IRET Properties, dated January 31, 1997, and as amended to date. The registration of the common shares does not necessarily mean that any of the LP Units will be submitted for redemption or that any of the common shares to be issued upon such redemption will be offered or sold by the selling shareholders.

     The selling shareholders may resell the common shares covered by this prospectus from time to time on the NASDAQ National Market or such other national securities exchange or automated interdealer quotation system on which our common shares are then listed or quoted, through negotiated transactions or otherwise at market prices prevailing at the time of the sale or at negotiated prices. The selling shareholders may engage brokers or dealers who may receive commissions or discounts from such selling shareholders.

Risks Related to Our Properties and Business

     Our increasing ownership of commercial properties subjects us to different risks than our traditional base of multi-family residential properties. Historically, the assets in our investment portfolio consisted predominantly of multi-family residential properties. More recently, our investment activities have caused this balance to shift so that the percentage of commercial properties held in our portfolio has increased significantly. Within the past 12 months, approximately 99.5% of our property acquisitions, on a total carrying amount basis, have been commercial properties, due to the greater availability of these properties on terms that meet our financial and strategic objectives. “Total carrying amount” is the amount we have invested in our properties (original investment plus improvements, if any) less accumulated depreciation. Based on total carrying amount, commercial properties now comprise a majority of our real estate assets, with the majority of our commercial properties being located in the Minneapolis/ St. Paul metropolitan area. Based on current market conditions, we anticipate that the percentage of commercial properties that we may acquire will continue to significantly exceed the number of multi-family residential properties that we may acquire during the next 12 months.

     Our historical experience in acquiring and operating multi-family residential properties may not be directly applicable to the acquisition and operation of commercial properties. Commercial properties involve different risks than multi-family residential properties, including:

1

Our earnings may be negatively affected if we are not successful in our acquisition and operation of commercial properties.

     Our geographic concentration in Minnesota and North Dakota may result in losses due to our significant exposure to the effects of economic and real estate conditions in those markets. For the fiscal year ended April 30, 2004, and the six month period ended October 31, 2004, we received approximately 79.7% and 80.2%, respectively, of our combined commercial segments gross revenue from commercial properties in Minnesota and approximately 8.9% and 6.4%, respectively, of our combined commercial segments gross revenue from commercial properties in North Dakota. For those same periods, we received approximately 21.4% and 21.7%, respectively, of our multi-family residential segment gross revenue from multi-family residential properties in Minnesota and 29.1% and 30.0%, respectively, of our multi-family residential segment gross revenue from multi-family residential properties in North Dakota. As of October 31, 2004, Minnesota accounted for approximately 79.5% of our combined commercial segments real estate portfolio and 22.4% of our multi-family residential segment real estate portfolio, each as determined by total asset value, while North Dakota accounted for approximately 6.0% of our combined commercial segments real estate portfolio and 27.2% of our multi-family residential segment real estate portfolio.

     As a result of this concentration, we are subject to substantially greater risk than if our investments were more geographically dispersed. Specifically, we are more significantly exposed to the effects of economic and real estate conditions in those particular markets, such as building by competitors, local vacancy and rental rates and general levels of employment and economic activity.

     The economic climate in Minnesota is highly dependent on the service, manufacturing and high technology industries. The North Dakota economy is dependent on the agricultural, government, business and personal services and wholesale and retail industries. Economic weakening, or lack of recovery from the recent weakness, in any of these industries may adversely affect the performance of our real estate portfolio by decreasing demand for rental space.

     Increasing physical and economic vacancy rates and declining rental rates will negatively impact earnings. As of October 31, 2004, approximately 1.0 million square feet, or 12.7% of our total commercial property square footage, was vacant. In addition, leases covering approximately 8.1% of our total combined commercial segments annualized base rents will expire during the remainder of fiscal 2005. Leases covering approximately 7.3% of our total combined commercial segments annualized base rents will expire during fiscal 2006. At October 31, 2004, the economic occupancy of our total commercial properties, on a stabilized property basis, was approximately 89.8%. We define “economic occupancy” as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue is determined by valuing occupied units or square footage at contract rates and vacant units or square footage at market rates. “Stabilized properties” are those properties that we owned for the entirety of both periods being compared, and include properties that were redeveloped or expanded during the period being compared. Properties purchased or sold during the periods being compared are excluded from our stabilized property analysis. If we are unable to rent or sell those properties that are vacant or affected by expiring leases, properties producing approximately 20% of our total combined commercial segments annualized base rents will be vacant by April 30, 2005. Even greater vacancies will be created to the extent that a number of tenants, or any one significant tenant, file for bankruptcy protection and reject our leases. At October 31, 2004, the economic occupancy of our multi-family residential properties, on a stabilized property basis, was approximately 91.1%. Multi-family residential vacancies could increase from current levels due to general economic conditions, local economic or competitive conditions, the trend toward home ownership facilitated by low interest rates, unsatisfactory property management, the physical condition of our properties or other factors. Increased vacancies in both our commercial and multi-family residential properties will negatively impact our earnings, will cause a decline in the value of our real estate portfolio and may adversely affect our ability to make distributions to the holders of our shares of beneficial interest.

     Multi-family residential property economic occupancy rates, on a stabilized property basis, were 91.1% for each of the six months ended October 31, 2004 and 2003. Commercial property economic occupancy rates, on a

2

stabilized property basis, decreased to 89.8% from 94.1% for the six months ended October 31, 2004 and 2003, respectively. To maintain our physical occupancy levels, we may offer tenants incentives, generally in the form of lower rents, which results in decreased revenues and income from operations at our stabilized properties. We estimate that rent concessions offered during the six months ended October 31, 2004, lowered our operating revenues by approximately $1.9 million, as compared to an estimated $1.2 million reduction in operating revenues attributable to rent concessions offered in the six months ended October 31, 2003.

     Inability to manage our rapid growth effectively may adversely affect our operating results. Our total assets have increased from $685 million at April 30, 2002, to $1,153.5 million at October 31, 2004, principally through the acquisition of additional real estate properties. Subject to our continued ability to raise equity capital and issue LP Units of IRET Properties, and identify suitable investment properties, our goal is to acquire approximately $100 million to $200 million of real estate assets on an annual basis. Effective management of this level of growth will present challenges, including:

If we are unable to effectively manage our growth, our operating results will be adversely affected.

     Competition may negatively impact our earnings. We compete with many kinds of institutions, including other REITs, private partnerships, individuals, pension funds and banks, for tenants and investment opportunities. Many of these institutions are active in the markets in which we invest and have greater financial and other resources that may be used to compete against us. With respect to tenants, this competition may affect our ability to lease our properties, the price at which we are able to lease our properties and the cost of required renovations or build-outs. With respect to acquisition and development investment opportunities, this competition may cause us to pay higher prices for new properties than we otherwise would have paid, or may prevent us from purchasing a desired property at all.

     An inability to continue to make accretive property acquisitions may adversely affect our ability to increase our operating income. From our fiscal year ended April 30, 2002, to our fiscal year ended April 30, 2004, our operating income decreased from $11.9 million to $10.9 million. Our basic and diluted net income per common share was $0.24 as of April 30, 2004, compared to $0.38 and $0.42, respectively, as of April 30, 2003 and 2002. If we are unable to continue to make real estate acquisitions on terms that meet our financial and strategic objectives, whether due to market conditions, a changed competitive environment or unavailability of capital, our ability to increase our operating income may be materially and adversely affected.

     High leverage on our overall portfolio may result in losses. As of October 31, 2004, our ratio of total indebtedness to total net assets was approximately 176.0%. As of April 30, 2004, 2003 and 2002, our percentage of total indebtedness to total net assets was approximately 178.0%, 186.0% and 211.0%, respectively. Under our Second Restated Trustees’ Regulations (Bylaws), we may increase our total indebtedness up to 300.0% of net assets before depreciation in the aggregate, or by an additional approximately $497.0 million. There is no limitation on the increase that may be permitted if approved by a majority of the independent members of our board of trustees and disclosed to the holders of our shares of beneficial interest in the next quarterly report, along with justification for any excess.

     This amount of leverage may expose us to cash flow problems if rental income decreases. Under those circumstances, in order to pay our debt obligations we might be required to sell properties at a loss or be unable to make distributions to the holders of our shares of beneficial interest. A failure to pay amounts due may result in a default on our obligations and the loss of the property through foreclosure.

3

     Our inability to renew, repay or refinance our debt may result in losses. We are subject to the normal risks associated with debt financing, including the risk that:

If we are unable to refinance our indebtedness on acceptable terms, or at all, we may be forced to dispose of one or more of the properties on disadvantageous terms, which may result in losses to us. These losses could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt. Furthermore, if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose upon the property, appoint a receiver and receive an assignment of rents and leases or pursue other remedies, all with a consequent loss of our revenues and asset value. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering our ability to meet the REIT distribution requirements of the Internal Revenue Code.

     The principal balance of our indebtedness in mortgage loans secured by individual properties totaled $682 million as of October 31, 2004. Of the outstanding mortgages, both fixed and variable, $8.9 million in principal amount will come due during fiscal year 2005, $18.7 million in principal amount will come due during fiscal year 2006 and the remaining balance will come due in later fiscal years.

     The cost of our indebtedness may increase which could affect our ability to make distributions and pay amounts due on our debt. We have incurred, and we expect to continue to incur, indebtedness that bears interest at a variable rate. As of October 31, 2004, $37.8 million, or approximately 5.5%, of the principal amount of our total mortgage indebtedness was subject to variable interest rate agreements. The interest rates on our variable rate mortgages range from approximately 4.0% to approximately 8.0%. An increase of one percent in our variable interest rate would collectively increase our interest payments by $378,000 annually. In addition, portions of our fixed-rate indebtedness incurred for past property acquisitions will come due on a periodic basis. For example, in each of our fiscal years ending April 30, 2005, 2006 and 2007, approximately $8.0 million to $19.0 million of our fixed-rate debt will come due. Accordingly, increases in interest rates will increase our interest costs, which could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt.

     Our current or future insurance may not protect us against possible losses. We carry comprehensive liability, fire, extended coverage and rental loss insurance with respect to our properties at levels that we believe to be adequate. However, the coverage limits of our current or future policies may be insufficient to cover the full cost of repair or replacement of all potential losses. Moreover, this level of coverage may not continue to be available in the future or, if available, may be available only at unacceptable cost or with unacceptable terms.

     Additionally, there may be certain extraordinary losses, such as those resulting from civil unrest, terrorism or environmental contamination, which are not generally, or fully, insured against because they are either uninsurable or not economically insurable. For example, we do not currently carry insurance against losses as a result of environmental contamination. Should an uninsured or underinsured loss occur to a property, we could be required to use our own funds for restoration or lose all or part of our investment in, and anticipated revenues from, the property. In any event, we would continue to be obligated on any mortgage indebtedness on the property. Any loss could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt.

     We have significant investments in medical office properties and adverse trends in healthcare provider operations may negatively affect our lease revenues from these properties. We have acquired a significant number of specialty medical properties and may acquire more in the future. As of October 31, 2004, our real estate portfolio included 29 medical office properties, having a total carrying amount of $200 million, or approximately 19% of the total asset value of our entire real estate portfolio. The healthcare industry is currently experiencing changes in the

4

demand for, and methods of delivery of, healthcare services; changes in third-party reimbursement policies; significant unused capacity in certain areas, which has created substantial competition for patients among healthcare providers in those areas; continuing pressure by private and governmental payors to reduce payments to providers of services; and increased scrutiny of billing, referral and other practices by federal and state authorities. Sources of revenue for our medical property tenants may include the federal Medicare program, state Medicaid programs, private insurance carriers and health maintenance organizations, among others. Efforts by such payors to reduce healthcare costs will likely continue, which may result in reductions or slower growth in reimbursement for certain services provided by some of our tenants. These factors may adversely affect the economic performance of some or all of our medical services tenants and, in turn, our lease revenues. In addition, if we or our tenants terminate the leases for these properties, or our tenants lose their regulatory authority to operate such properties, we may not be able to locate suitable replacement tenants to lease the properties for their specialized uses. Alternatively, we may be required to spend substantial amounts to adapt the properties to other uses. Any loss of revenues and/or additional capital expenditures occurring as a result could hinder our ability to make distributions to the holders of our shares of beneficial interest.

     Adverse changes in applicable laws may affect our potential liabilities relating to our properties and operations. Increases in real estate taxes and income, service and transfer taxes cannot always be passed through to all tenants in the form of higher rents. As a result, any increase may adversely affect our cash available for distribution, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt. Similarly, changes in laws that increase the potential liability for environmental conditions existing on properties, that increase the restrictions on discharges or other conditions or that affect development, construction and safety requirements may result in significant unanticipated expenditures that could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt. In addition, future enactment of rent control or rent stabilization laws or other laws regulating multi-family residential properties may reduce rental revenues or increase operating costs.

     Complying with laws benefiting disabled persons may affect our costs and investment strategies. Federal, state and local laws and regulations designed to improve disabled persons’ access to and use of buildings, including the Americans with Disabilities Act, may require modifications to, or restrict renovations of, existing buildings. Additionally, these laws and regulations may require that structural features be added to buildings under construction. Any legislation or regulations that may be adopted in the future may impose further burdens or restrictions on us with respect to improved access to, and use of these buildings by, disabled persons. The costs of complying with these laws and regulations may be substantial and limits or restrictions on construction, or the completion of required renovations, may limit the implementation of our investment strategy or reduce overall returns on our investments. This could have an adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt.

     We may be responsible for potential liabilities under environmental laws. Under various federal, state and local laws, ordinances and regulations, a current or previous owner or operator of real estate may be liable for the costs of removal of, or remediation of, hazardous or toxic substances in, on, around or under that property. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence of the hazardous or toxic substances. The presence of these substances, or the failure to properly remediate any property containing these substances, may adversely affect the owner’s or operator’s ability to sell or rent the affected property or to borrow using the property as collateral. Persons who arrange for the disposal or treatment of hazardous or toxic substances may also be liable for the costs of removal of, or remediation of, these substances at that disposal or treatment facility, whether or not the facility is owned or operated by that person. In connection with our current or former ownership (direct or indirect), operation, management, development and/or control of real properties, we may be potentially liable for removal or remediation costs with respect to hazardous or toxic substances as those properties, as well as certain other costs, including governmental fines and claims for injuries to persons and property. A finding of liability for an environmental condition as to any one or more properties could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt.

     It is generally our policy to obtain a Phase I environmental study on each property that we seek to acquire. If the Phase I indicates any possible environmental problems, it is our policy is to order a Phase II study, which

5

involves testing the soil and ground water for actual hazardous substances. However, Phase I and Phase II environmental studies, or any other environmental studies undertaken with respect to any of our current or future properties, may not reveal the full extent of potential environmental liabilities. We currently do not carry insurance for environmental liabilities.

     We may be unable to retain or attract qualified management. We are dependent upon our senior officers for essentially all aspects of our business operations. Our senior officers have experience in the specialized business segments in which we operate and the loss of them would likely have a material adverse effect on our operations. We do not have employment contracts with any of our senior officers. As a result, any senior officer may terminate his or her relationship with us at any time, without providing advance notice. The location of our corporate headquarters in Minot, North Dakota, may make it more difficult and expensive to attract, relocate and retain current and future officers and employees.

     Failure to achieve and maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business, operating results and stock price, and compliance will result in additional expenses. We are in the process of documenting and testing our internal control procedures in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent auditors addressing these assessments. During the course of our testing we may identify deficiencies which we may not be able to remediate in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404. In addition, if we fail to maintain the adequacy of our internal controls, as such standards may be modified, supplemented or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act. Failure to achieve and maintain an effective internal control environment could have a material adverse effect on our business, operating results, and stock price. Additionally, our efforts to comply with Section 404 of the Sarbanes-Oxley Act and the related regulations have required, and we believe will continue to require, the commitment of significant financial and managerial resources.

Risks Related to the Purchase of our Shares of Beneficial Interest

     Our future growth depends, in part, on our ability to raise additional equity capital, which will have the effect of diluting the interests of the holders of our common shares. Our future growth depends upon, among other things, our ability to raise equity capital and issue LP Units of IRET Properties. The issuance of additional common shares and of LP Units, for which we subsequently issue common shares upon the redemption of LP Units, will dilute the interests of the current holders of our common shares.

     We may issue additional classes or series of our shares of beneficial interest with rights and preferences that are superior to the rights and preferences of our common shares. Without the approval of the holders of our common shares, our board of trustees may establish additional classes or series of our shares of beneficial interest, and, like our Series A preferred shares, such classes or series may have rights and preferences that are superior to the rights and preferences of our common shares. Any such class or series of preferred shares of beneficial interest may contain dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences or other rights and preferences that are superior to the rights of the holders of our common shares. We have issued in the past, and may issue in the future, preferred shares of beneficial interest having rights and preferences that are superior to those of our common shares. Such offering will only occur if and when, among other things, the market conditions for an offering of preferred shares of beneficial interest are such that the dividend rate established in respect of the preferred shares of beneficial interest will be acceptable to us and our board of trustees.

     Payment of distributions on our shares of beneficial interest is not guaranteed. Our board of trustees must approve our payment of distributions and may elect at any time, or from time to time, and for an indefinite duration, to reduce the distributions payable on our shares of beneficial interest or to not pay distributions on our shares of beneficial interest. Our board of trustees may reduce distributions for a variety of reasons, including, but not limited to, the following:

6

     Changes in market conditions could adversely affect the price of our shares of beneficial interest. As is the case with any publicly-traded securities, certain factors outside of our control could influence the value of our common shares, Series A preferred shares and any other classes or series of preferred shares of beneficial interest to be issued in the future. These conditions include, but are not limited to:

     Low trading volume on the NASDAQ National Market may prevent the timely resale of our common shares. No assurance can be given that a holder of our common shares will be able to resell such shares when desired. Our common shares are currently traded on the NASDAQ National Market. The average daily trading volume for the period of May 1, 2003, through April 30, 2004, was 50,297 shares and the average monthly trading volume for the period of May 2003 through April 2004 was 1,293,517 shares. The average daily trading volume for the period of May 1, 2004 through October 31, 2004 was 59,522 shares and the average monthly trading volume for the period of May 2004 through October 2004 was 1,249,963 shares. As a result of this trading volume, an owner of our common shares may encounter difficulty in selling such shares in a timely manner and may incur a substantial loss.

Risks Related to Our Structure and Organization

     We may incur tax liabilities as a consequence of failing to qualify as a REIT. Although our management believes that we are organized and have operated and are operating in such a manner to qualify as a “real estate investment trust,” as that term is defined under the Internal Revenue Code, no assurance can be given that we have in fact operated, or will be able to continue to operate, in a manner to qualify or remain so qualified. Qualification as a real estate investment trust, or REIT, involves the application of highly technical and complex Internal Revenue Code provisions for which there are only limited judicial or administrative interpretations, and further involves the determination of factual matters and circumstances not entirely within our control. See “Certain Tax Considerations” below. For example, in order to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources, and we must make distributions to the holders of our shares of beneficial interest aggregating annually at least 90% of our REIT taxable income (excluding net capital gains). Thus, to the extent revenues from non-qualifying sources, such as income from third-party management, represents more than five percent of our gross income in any taxable year, we will not satisfy the 95% income test and may fail to qualify as a REIT, unless certain relief provisions contained in the Internal Revenue Code apply. Even if relief provisions apply, however, a tax would be imposed with respect to excess net income. Additionally, if IRET Properties or one or more of our subsidiaries is determined to be taxable as a corporation, we may fail to qualify as a REIT. Either our failure to qualify as a REIT, for any reason, or the imposition of taxes on excess net income from non-qualifying sources, could have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt. Furthermore, new legislation, regulations, administrative interpretations or court decisions could change the tax laws with respect to our qualification as a REIT or the federal income tax consequences of our qualification.

7

     If we failed to qualify as a REIT, we would be subject to federal income tax (including any applicable alternative minimum tax) on our taxable income at corporate rates, which would likely have a material adverse effect on us, our ability to make distributions to the holders of our shares of beneficial interest and our ability to pay amounts due on our debt. In addition, unless entitled to relief under applicable statutory provisions, we would also be disqualified from treatment as a REIT for the four taxable years following the year during which we lost our qualification. This treatment would reduce funds available for investment or distributions to the holders of our shares of beneficial interest because of the additional tax liability to us for the year or years involved. In addition, we would no longer be required to make distributions to holders of our common shares. To the extent that distributions to the holders of our shares of beneficial interest would have been made in anticipation of qualifying as a REIT, we might be required to borrow funds or to liquidate certain investments to pay the applicable tax.

     Certain provisions of our Third Restated Declaration of Trust may limit a change in control and deter a takeover. In order to maintain our qualification as a REIT, our Articles of Amendment and Third Restated Declaration of Trust, as amended to date, or our Third Restated Declaration of Trust, provides that any transaction, other than a transaction entered into through the NASDAQ National Market or other similar exchange, that would result in our disqualification as a REIT under Section 856 of the Internal Revenue Code, including any transaction that would result in (i) a person owning in excess of the ownership limit, which as of the date of this prospectus supplement is 9.8%, in number or value, of our outstanding shares of beneficial interest, (ii) fewer than 100 people owning our shares of beneficial interest, (iii) us being “closely held” within the meaning of Section 856(h) of the Internal Revenue Code, or (iv) 50% or more of the fair market value of our shares of beneficial interest being held by persons other than “United States persons,” as defined in Section 7701(a)(30) of the Internal Revenue Code, will be void ab initio. If the transaction is not void ab initio, then the shares of beneficial interest in excess of the ownership limit, that would cause us to be closely held, that would result in 50% or more of the fair market value of our shares of beneficial interest to be held by persons other than United States persons or that otherwise would result in our disqualification as a REIT, will automatically be exchanged for an equal number of excess shares, and these excess shares will be transferred to an excess share trustee for the exclusive benefit of the charitable beneficiaries named by our board of trustees. These limitations may have the effect of preventing a change in control or takeover of us by a third-party, even if the change in control or takeover would be in the best interests of the holders of our shares of beneficial interest.

     Our board of trustees may make changes to our major policies without approval of the holders of our shares of beneficial interest. Our major policies, including policies relating to development, acquisitions, financing, growth, debt capitalization and distributions, are determined by our board of trustees. Our board of trustees may amend or revoke those policies, and other policies, without advance notice to, or the approval of, the holders of our shares of beneficial interest.

IRET

     We are a self-advised equity REIT organized under the laws of North Dakota. Our business consists of owning and operating income-producing real properties. Our investments include multi-family residential properties, consisting of apartment buildings, complexes and communities, and commercial properties, consisting of office, industrial, medical and retail properties. These properties are located primarily in the upper Midwest states of Minnesota and North Dakota.

     Our primary source of income and cash is rents associated with multi-family residential and commercial property leases. Our commercial properties are typically leased to tenants under long term lease arrangements, with no single tenant currently accounting for more than approximately 5.6% of our total annual commercial rental revenues. At October 31, 2004, the economic occupancy rate for our stabilized multi-family residential properties was approximately 91.1%, and the economic occupancy of our total commercial properties, on a stabilized property basis, was approximately 89.8%. We define “economic occupancy” as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue is determined by valuing occupied units or square footage at contract rates and vacant units or square footage at market rates. “Stabilized properties” are those properties that we owned for the entirety of both periods being compared, and include properties that were redeveloped or expanded during the period being compared. Properties purchased or sold during the periods being

8

compared are excluded from our stabilized property analysis. Results reported on a stabilized property basis are not computed in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

     We operate in a manner intended to enable us to qualify as a REIT under the Internal Revenue Code. We own our assets and conduct our day-to-day business operations through an operating partnership, IRET Properties, a North Dakota Limited Partnership, of which IRET, Inc., a North Dakota corporation and our wholly-owned subsidiary, is the sole general partner.

RECENT DEVELOPMENTS

     In November 2004 we completed a best efforts offering to sell up to 1.5 million of our common shares of beneficial interest at $10.15 per share. We sold 1.4 million shares in this offering, and received proceeds of approximately $13.4 million, after broker commissions totaling $0.9 million, but before other expenses of the offering.

     On January 3, 2005, our board of trustees declared a regular quarterly distribution of 16.15 cents per common share and LP Unit payable on or about January 27, 2005, to common shareholders and unitholders of record at the close of business on January 13, 2005. This 16.15 cent per common share/LP Unit distribution is the 135^th consecutive quarterly distribution paid by IRET since its inception in 1970, and represents an increase of .05 cents or 0.3% over the previous regular quarterly distribution of 16.10 cents per common share/LP Unit paid October 1, 2004.

NO PROCEEDS TO IRET

     We will not receive any proceeds from the issuance of the common shares, if any, covered by this prospectus or from the resale of the common shares, if any, covered by this prospectus by the selling shareholders. All of the proceeds from the resale of the common shares covered by this prospectus will go to the selling shareholders who offer and sell their shares.

SELLING SHAREHOLDERS

     We may issue the common shares covered by this prospectus to the selling shareholders in exchange for LP Units if and to the extent that the selling shareholders redeem LP Units and we elect to issue common shares in exchange for such LP Units. The selling shareholders will have received all common shares that they may offer for sale under the prospectus by redeeming the LP Units to which this prospectus relates. The following table sets forth certain information with respect to the selling shareholders and their ownership of common shares as of January 20, 2005. No selling shareholder has held any position, office or had any other material relationship with us, or any of our predecessors or affiliates, during the past three years. Except as indicated below, the common shares owned by each selling shareholder, including all common shares to be issued in exchange for currently redeemable LP Units for common shares covered by this prospectus, represents less than 1.0% of the sum of the common shares outstanding as of January 20, 2005, plus all common shares to be issued in exchange for LP Units by the selling shareholders pursuant to this prospectus, assuming redemption of all LP Units in exchange for common shares.

     Since the selling shareholders may sell all, some or none of the common shares issued upon redemption of LP Units, and since there are currently no agreements, arrangements or understandings with respect to the sale of any of such common shares, no estimate can be given as to the number or percentage of common shares that will be held by the selling shareholders upon termination of any offering made hereby. The common shares covered by this prospectus represent approximately 1.0% of the sum of our total common shares outstanding as of January 20, 2005, plus all common shares to be issued in exchange for LP Units by the selling shareholders pursuant to this prospectus, assuming redemption of all LP Units in exchange for common shares.

PLAN OF DISTRIBUTION

     This prospectus relates to the possible issuance of up to 440,758 common shares if, and to the extent that, the holders of an equal number of LP Units submit such LP Units for redemption and we issue common shares in exchange for such redeemed LP Units. We will not receive any proceeds from any issuance of common shares in exchange for LP Units. This prospectus also relates to the possible offer and sale by the selling shareholders, from time to time, of any common shares we issue in exchange for LP Units. We will not receive any proceeds from the sale of the common shares by the selling shareholders.

     We are registering the common shares covered by this prospectus for resale pursuant to our obligations under the Agreement of Limited Partnership of IRET Properties in order to provide the transferees of the selling shareholders with freely tradable securities. Registration does not, however, necessarily mean that any LP Units will be submitted for redemption or that any of the common shares to be issued upon such redemption will be offered or sold by the selling shareholders.

     The selling shareholders, or their pledgees, donees, transferees or other successors in interest, may offer and sell the common shares covered by this prospectus in the following manner:

10

The offering price of the common shares covered by this prospectus and offered from time to time will be determined by the selling shareholders and, at the time of determination, may be higher or lower than the market price of the common shares on the NASDAQ National Market.

     In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from a selling shareholder or from purchasers of offered common shares for whom they may act as agents, and underwriters may sell offered common shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers from whom they may act as agents.

     Offered common shares may be sold directly or through broker-dealers acting as principal or agent, or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. The methods by which offered common shares may be sold include:

     The selling shareholders and any underwriters, dealer or agents participating in the distribution of offered common shares may be deemed to be “underwriters” within the meaning of the Securities Act of 1933. Any profit on the sale of offered common shares by the selling shareholders and any commissions received by any such broker-dealers may be deemed to be underwriting commissions under the Securities Act of 1933.

     When a selling shareholder elects to make a particular offer of common shares, a prospectus supplement, if required, will be distributed that identifies any underwriters, dealers or agents and any discounts, commissions and other terms constituting compensation from such selling shareholder and any other required information.

     In order to comply with state securities laws, if applicable, offered common shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, offered common shares may not be sold unless they have been registered or qualified for sale in such state or an exemption from such registration or qualification requirement is available and complied with.

     We have agreed to pay all costs and expenses incurred in connection with the registration under the Securities Act of 1933 of the common shares covered by this prospectus, including, but not limited to, all registration and filing fees, printing expenses and fees and disbursements of our legal counsel and accountants. The selling shareholders will pay any brokerage fees and commissions, fees and disbursements of legal counsel for the

11

selling shareholders and stock transfer and other taxes attributable to the sale of common shares covered by this prospectus.

DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

     The following is a summary of the material terms of our shares of beneficial interest. This summary is not a complete legal description of the common shares offered by this prospectus or our Series A preferred shares and is qualified in its entirety by reference to our Third Restated Declaration of Trust, the Articles Supplementary to our Third Restated Declaration of Trust classifying and designating our Series A preferred shares and our Bylaws. We have filed copies of our Third Restated Declaration of Trust, the Articles Supplementary to our Third Restated Declaration of Trust classifying and designating our Series A preferred shares and our Bylaws with the Securities and Exchange Commission and have incorporated by reference such documents as exhibits to the registration statement of which this prospectus is a part.

General

     We are authorized, under our Third Restated Declaration of Trust, to issue an unlimited number of our shares of beneficial interest. Our board of trustees is authorized, under our Third Restated Declaration of Trust, to provide for the issuance of shares of beneficial interest upon terms and conditions and pursuant to agreements as the board of trustees may determine and, further, to establish by resolution more than one class or series of shares of beneficial interest and to fix the relative rights and preferences of these different classes or series. The rights and preferences of any class or series of shares of beneficial interest will be stated in the articles supplementary to our Third Restated Declaration of Trust establishing the terms of that class or series adopted by our board of trustees and will become part of our Third Restated Declaration of Trust. As of January 20, 2005, our authorized shares of beneficial interest consisted of an unlimited number of common shares, of which 44,090,132 were issued and outstanding, and an unlimited number of Series A preferred shares, of which 1,150,000 were issued and outstanding.

     The voting rights and rights to distributions of the holders of common shares are subject to the prior rights of the holders of our Series A preferred shares and any other subsequently-issued classes or series of preferred shares. Unless otherwise required by applicable law or regulation, other classes or series of preferred shares are issuable without further authorization by holders of the common shares and on such terms and for such consideration as may be determined by our board of trustees. Other classes or series of preferred shares may have varying voting rights, redemption and conversion features, distribution (including liquidating distribution) rights and preferences, and other rights, including rights of approval of specified transactions. Any subsequently-issued class or series of preferred shares could be given rights that are superior to rights of holders of common shares and a class or series having preferential distribution rights could limit common share distributions and reduce the amount holders of common shares would otherwise receive on dissolution.

Ownership and Transfer Restrictions.

     Our Third Restated Declaration of Trust contains provisions that are intended to help preserve our status as a REIT for federal income tax purposes. Specifically, our Third Restated Declaration of Trust provides that any transaction, other than a transaction entered into through the NASDAQ National Market or other similar exchange, that would result in our disqualification as a REIT under Section 856 of the Internal Revenue Code, including any transaction that would result in (i) a person owning shares of beneficial interest in excess of the ownership limit, which as of the date of this prospective supplement is 9.8%, in number or value, of our outstanding shares of beneficial interest, (ii) less than 100 people owning our shares of beneficial interest, (iii) us being closely held, or (iv) 50% or more of the fair market value of our shares of beneficial interest being held by persons other than United States persons, will be void ab initio. If such transaction is not void ab initio, then the shares of beneficial interest that are in excess of the ownership limit, that would cause us to be closely held, that would result in 50% or more of the fair market value of our shares of beneficial interest to be held by persons other than United States persons or that otherwise would result in our disqualification as a REIT, would automatically be exchanged for an equal number of “excess shares,” and these excess shares will be transferred to an “excess share trustee” for the exclusive benefit of the charitable beneficiaries named by our board of trustees.

12

     In such event, any distributions on excess shares will be paid to the excess share trust for the benefit of the charitable beneficiaries. The excess share trustee will be entitled to vote the excess shares, if applicable, on any matter. The excess share trustee may only transfer the excess shares held in the excess share trust as follows:

We have certain rights to purchase excess shares from the excess share trustee and must have waived these rights prior to a transfer as described above.

Common Shares

     General. Our Third Restated Declaration of Trust authorizes the issuance of an unlimited number of our common shares. As of January 20, 2005, there were 44,090,132 of our common shares outstanding and 10,938,432 of our common shares to be issued upon conversion of previously issued LP Units, and there were no warrants, options or other contractual arrangements, other than the LP Units, requiring the issuance of our common shares or any other shares of beneficial interest.

     All of our common shares offered by this prospectus will be duly authorized, fully paid and nonassessable when exchanged for LP Units in accordance with the terms of the Agreement of Limited Partnership of IRET Properties.

     Voting Rights. Subject to the provisions of our Third Restated Declaration of Trust regarding the restriction on the transfer of our common shares, our common shares have non-cumulative voting rights at the rate of one vote per common share on all matters submitted to the shareholders, including the election of members of our board of trustees.

     Our Third Restated Declaration of Trust generally provides that whenever any action is to be taken by the holders of our common shares, including the amendment of our Third Restated Declaration of Trust if such amendment is previously approved by our board of trustees, such action will be authorized by a majority of the voting power of the holders of our common shares present in person or by proxy at a meeting at which a quorum is present, except as otherwise required by law, our Third Restated Declaration of Trust or our Bylaws. Our Third Restated Declaration of Trust further provides the following:

13

Our Third Restated Declaration of Trust also permits our board of trustees, by a two-thirds vote and without any action by the holders of our common shares, to amend our Third Restated Declaration of Trust from time to time as necessary to enable us to continue to qualify as a real estate investment trust under the Internal Revenue Code.

     Dividend, Distribution, Liquidation and Other Rights. Subject to the preferential rights of our Series A preferred shares, any other preferred shares of beneficial interest that we may issue in the future and the provisions of the Third Restated Declaration of Trust regarding the restriction on the transfer of our common shares, holders of our common shares are entitled to receive dividends on their common shares if, as and when authorized and declared by our board of trustees and to share ratably in our assets legally available for distribution to our shareholders in the event of our liquidation, dissolution or winding up after payment of, or adequate provision for, all known debts and liabilities. Our common shares have equal dividend, distribution, liquidation and other rights. Our common shares have no preference, conversion, exchange, sinking fund or redemption rights.

     Listing. Our common shares are listed on the NASDAQ National Market under the symbol “IRETS.”

     Transfer Agent and Registrar. We act as our own transfer agent and registrar with respect to our common shares.

Series A Preferred Shares

     General. Our Third Restated Declaration of Trust, as amended by the Articles Supplementary, authorizes the issuance of an unlimited number of our Series A preferred shares. As of January 20, 2005, there were 1,150,000 of our Series A preferred shares outstanding and there were no warrants, options or other contractual arrangements requiring the issuance of additional Series A preferred shares or any other shares of beneficial interest. Unless redeemed, our Series A preferred shares have a perpetual term with no stated maturity date.

     Ranking. With respect to the payment of distributions and distribution of our assets and rights upon our liquidation, dissolution or winding up, whether voluntary or involuntary, our Series A preferred shares will rank:

We do not currently have any other shares of beneficial interest outstanding that rank on a parity with, or senior to, our Series A preferred shares.

     Distributions. Holders of our Series A preferred shares will be entitled to receive, when, as and if declared by our board of trustees, out of funds legally available for that purpose, cumulative quarterly cash distributions at the rate of 8.25% of the $25.00 liquidation preference per year (equivalent to an annual rate of $2.0625 per Series A preferred share). Distributions on our Series A preferred shares will accrue and be cumulative from and including the date of initial issuance or from and including the day immediately following the most recent date as to which distributions have been paid. Distributions will be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, or, if not a business day, the succeeding business day (without interest for the

14

intervening period). Distributions will accrue regardless of whether we have earnings, whether we have funds legally available for payment or whether the distributions are declared. The first distribution on our Series A preferred shares was paid on June 30, 2004. Distributions will be computed on the basis of a 360-day year consisting of twelve 30-day months. Each payment of distributions will include distributions accrued to and including the date on which paid. Distributions will be payable to record holders of our Series A preferred shares as they appear in our records at the close of the business on the applicable record date, which will be the 15th day of the calendar month in which the applicable distribution payment date falls or such other date designated by our board of trustees for the payment of distributions that is not more than 30 nor less than 10 days prior to the distribution payment date.

     No full distributions will be authorized or paid or set apart for payment on any class or series of shares of beneficial interest ranking, as to distributions, on a parity with our Series A preferred shares unless all accrued distributions on our Series A preferred shares for all past distribution periods and the then current distribution period have been, or contemporaneously are, authorized and paid in full or a sum sufficient for the payment in full of such distributions is set apart for that payment. When distributions are not paid in full (or a sum sufficient for their full payment is not so set apart) on our Series A preferred shares and any other class or series of shares of beneficial interest ranking on a parity as to distributions with our Series A preferred shares, all distributions declared upon our Series A preferred shares and any other such shares of beneficial interest will be authorized pro rata so that the amount of distributions authorized per share on our Series A preferred shares and all other such shares of beneficial interest will in all cases bear to each other the same ratio that accrued and unpaid distributions per share on our Series A preferred shares and all other shares of beneficial interest bear to each other.

     Except as provided in the immediately preceding paragraph, unless all accrued distributions on our Series A preferred shares for all past distribution periods and the then current distribution period have been, or contemporaneously are, authorized and paid in full or a sum sufficient for the payment in full of such distributions is set apart for payment, no distributions (other than in the form of our common shares or any other shares of beneficial interest ranking junior to our Series A preferred shares as to distributions and upon our liquidation, dissolution or winding up, whether voluntary or involuntary) or other distribution will be authorized, paid or set aside for payment or made upon our common shares or any other shares of beneficial interest ranking junior to, or on a parity with, our Series A preferred shares as to distributions or upon our liquidation, dissolution or winding up, whether voluntary or involuntary, nor will any common shares or any other shares of beneficial interest ranking junior to or on a parity with our Series A preferred shares as to distributions or upon our liquidation, dissolution or winding up, whether voluntary or involuntary, be redeemed, purchased or otherwise acquired for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such shares of beneficial interest) by us (except by conversion into or exchange for other shares of beneficial interest ranking junior to our Series A preferred shares as to distributions and upon our liquidation, dissolution or winding up, whether voluntary or involuntary, and except for the acquisition of shares of beneficial interest that have been designated as “excess shares” in accordance with the terms of our Third Restated Declaration of Trust).

     Distributions on our Series A preferred shares will accrue whether or not we have earnings, whether or not there are funds legally available for the payment of the distributions and whether or not the distributions are authorized. Accrued but unpaid distributions on our Series A preferred shares will not bear interest and holders of our Series A preferred shares will not be entitled to any distributions in excess of full accrued distributions as described above. No distributions on our Series A preferred shares will be authorized by our board of trustees or will be paid or set apart for payment by us at such time as the terms and provisions of any agreement of ours, including any agreement relating to our indebtedness, prohibits the authorization, payment or setting apart for payment or provides that the authorization, payment or setting apart for payment would constitute a breach of any agreement or a default under any agreement, or if the authorization, payment or setting apart for payment is restricted or prohibited by law.

     Any distribution payment made on our Series A preferred shares will first be credited against the earliest accrued but unpaid distribution due with respect to the shares which remains payable.

     Liquidation. In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, the holders of our Series A preferred shares will be entitled to be paid out of our assets legally available for distribution to the holders of our shares of beneficial interest a liquidation preference of $25.00 per share, plus an

15

amount equal to any accrued and unpaid distributions to and including the date of the liquidation, dissolution or winding up, before any distribution or payment may be made to the holders of our common shares or any other class or series of shares of beneficial interest issued by us ranking junior to our Series A preferred shares as to liquidation rights. In the event that, upon our liquidation, dissolution or winding up, whether voluntary or involuntary, our legally available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series A preferred shares and the corresponding amounts payable on all other classes or series of shares of beneficial interest issued by us ranking on a parity with our Series A preferred shares as to liquidation rights, then the record holders of our Series A preferred shares and all other classes or series of shares of beneficial interest issued by us ranking on a parity with our Series A preferred shares as to liquidation rights will share ratably in any distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of our Series A preferred shares will have no right or claim to any of our remaining assets.

     The record holders of our Series A preferred shares will be entitled to written notice of any liquidation, dissolution or winding up. Our consolidation or merger with or into any other trust, partnership, limited liability company, corporation or other entity, or the consolidated or merger of any other trust, partnership, limited liability company, corporation or other entity with or into us, will not be deemed to constitute our liquidation, dissolution or the winding up if, following the transaction, our Series A preferred shares remain outstanding as duly authorized shares of beneficial interest of us or any successor entity having the same rights and preferences as prior to the transaction.

     Redemption at Our Option. Our Series A preferred shares will not be redeemable at our option prior to April 26, 2009, except that in order to ensure that we remain qualified as a REIT for federal income tax purposes, our Series A preferred shares will be subject to the provisions of our Third Restated Declaration of Trust that provide that Series A preferred shares owned by a shareholder in excess of the ownership limit described in that document will be automatically designated “excess shares” and be transferred as described below under “Restrictions on Ownership.”

     On or after April 26, 2009, we, at our option upon not less than 30 nor more than 60 days’ written notice, may redeem our Series A preferred shares, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus accrued and unpaid distributions thereon to and including the date of redemption (except as provided below), if any, and without interest. Unless all accrued distributions for all past distribution periods and the then current distribution period on all Series A preferred shares and any other of our shares of beneficial interest ranking on a parity with our Series A preferred shares as to distributions or upon our liquidation, dissolution or winding up, whether voluntary or involuntary, have been, or contemporaneously are, authorized and paid in full or a sum sufficient for the payment in full of such distributions is set apart for payment, no Series A preferred shares or other shares of beneficial interest ranking on a parity will be redeemed unless all outstanding Series A preferred shares and other shares of beneficial interest ranking on a parity are simultaneously redeemed. However, the foregoing will not prevent the purchase or acquisition of Series A preferred shares pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding Series A preferred shares and other shares of beneficial interest ranking on a parity. If fewer than all of the outstanding Series A preferred shares are to be redeemed, our Series A preferred shares to be redeemed will be determined pro rata (as nearly as practicable without creating fractional shares) or in such other equitable manner prescribed by our board of trustees that will not result in a violation of the restrictions specified below under “Restrictions on Ownership.”

     We are required to give the holders of our Series A preferred shares prior written notice of redemption of our Series A preferred shares. Notice of redemption will be mailed by us, postage prepaid, not less than 30 days nor more than 60 days prior to the date fixed for redemption, addressed to the respective record holders of our Series A preferred shares to be redeemed at their respective addresses as they appear on our records. No failure to give such notice or defect in the notice or in the mailing of the notice will affect the validity of the proceedings for the redemption of any Series A preferred shares except as to the holder to whom notice was defective or not given. Each notice will state:

16

If fewer than all of the outstanding Series A preferred shares are to be redeemed, the notice mailed to each holder will also specify the number of Series A preferred shares to be redeemed from each such holder and the method by which shares will be selected for redemption.

     On or after the redemption date, once a record holder of Series A preferred shares to be redeemed surrenders the certificates representing their Series A preferred shares at the place designated in the redemption notice, the redemption price of such Series A preferred shares, including any accrued and unpaid distributions payable, will be paid to the person who surrendered such certificates and each surrendered certificate will be canceled. In the event that fewer than all our Series A preferred shares represented by any certificate are to be redeemed, a new certificate will be issued representing the unredeemed Series A preferred shares.

     At our election, we may, prior to the redemption date, irrevocably deposit the redemption price (including accrued and unpaid distributions) of our Series A preferred shares called for redemption in trust for the holders thereof with a bank or trust company, in which case the notice to holders of our Series A preferred shares to be redeemed will:

Any monies deposited that remain unclaimed at the end of two years after the redemption date will be returned to us by such bank or trust company and after that time the holder must look to us for payment.

     Except as provided above, we will make no payment or allowance for unpaid distributions, whether or not in arrears, on Series A preferred shares to be redeemed.

     If notice of redemption of any Series A preferred shares has been given and if the funds necessary for that redemption have been set apart by us in trust for the benefit of the holders of any Series A preferred shares so called for redemption, then from and after the redemption date distributions will cease to accrue on those Series A preferred shares, those Series A preferred shares will no longer be deemed outstanding, those Series A preferred shares will not thereafter be transferred (except with our consent) on our books and all rights of the holders of those Series A preferred shares will terminate, except the right to receive the redemption price (including all accrued and unpaid distributions to and including the redemption date).

     Our Series A preferred shares have no stated maturity date and will not be subject to any sinking fund.

     Redemption at the Holder’s Option. If at any time there has been a change in control (as defined below), each holder of Series A preferred shares will have the right, for a period of 90 days from the date of the change in control, to require us to redeem all or any portion of that holder’s Series A preferred shares. Not later than 130 days after the date of the change in control (or, if that date is a Saturday, Sunday or legal holiday, the next day that is not a Saturday, Sunday or legal holiday), we will redeem all Series A preferred shares the holder has elected to have

17

redeemed in a written notice delivered to us on or prior to the 90th day after the change in control. The redemption price will be $25.00 per share, plus accrued and unpaid distributions, if any, to and including the date of redemption.

     A “change in control” will have occurred if any of the following events have taken place:

     There is no precise, established definition of the term “all or substantially all of our assets” under applicable law and accordingly there may be uncertainty as to whether the foregoing provision would apply to a sale of less than all of our assets.

     Voting Rights. Except as indicated below, the holders of our Series A preferred shares will not have any voting rights other than as required by applicable law. On any matter on which our Series A preferred shares are entitled to vote, including any action by written consent, each Series A preferred share will be entitled to one vote.

     Whenever distributions payable on our Series A preferred shares are in arrears for six or more quarterly periods, whether or not consecutive, holders of our Series A preferred shares (voting together as a class with holders of all other classes or series of shares of beneficial interest ranking on a parity with our Series A preferred shares as to distributions and upon our liquidation, dissolution or winding up, whether voluntary or involuntary, upon which like voting rights have been conferred and are exercisable) will be entitled to elect two additional trustees to serve on our board of trustees, who will be elected for one-year terms (subject to earlier termination as described below). Such election will be at a special meeting called by the record holders of at least 10% of the Series A preferred shares or the record holders of any other class or series of shares of beneficial interest upon which like voting rights have been conferred and are exercisable (or at our next special meeting or annual meeting if notice of such meeting is given less than 90 days before our next special meeting or annual meeting) and each subsequent annual meeting until all of the distributions on the Series A preferred shares and all other classes of our shares of beneficial interest upon which like voting rights have been conferred and are exercisable for the past distribution periods and the then current distribution period have been fully paid or authorized and a sum sufficient for payment thereof set aside in full. Election will require a vote of the holders of a majority of the Series A preferred shares and shares of all other classes or series of our shares of beneficial interest upon which like voting rights have been conferred and are exercisable then outstanding, voting as a single class. Upon such election, the size of our board of trustees will be increased by two trustees. If and when all such accumulated distributions have been paid on the Series A preferred shares and all other classes or series of shares of beneficial interest upon which like voting rights have been conferred and are exercisable, the term of office of each of the additional trustees so elected will terminate and the size of our board of trustees will be reduced accordingly. So long as a distribution default continues, any vacancy in the office of additional trustees elected as described in this paragraph may be filled by written consent of the other additional trustee who remains in office or, if no additional trustee remains in office, by a vote of the holders of a majority of the Series A preferred shares and shares of all other classes or series of our shares of beneficial interest upon which like voting rights have been conferred and are exercisable then outstanding, voting as a single class. Each of the trustees elected as described in this paragraph will be entitled to one vote on any matter.

18

     The affirmative vote or consent of the holders of at least two-thirds of the then outstanding Series A preferred shares and shares of each other class or series of shares of beneficial interest ranking on a parity with respect to the payment of distributions or the distribution of assets upon our liquidation, dissolution or winding up, whether voluntary or involuntary, that is similarly affected, voting as a single class, will be required to:

     With respect to any of the events described in the preceding paragraph, the occurrence of any such event will not be deemed to materially adversely affect any right, preference, privilege or voting power of any class or series of shares of beneficial interest or the holders of such shares if, immediately after any such event:

     Except as may be required by law, holders of our Series A preferred shares will not be entitled to vote with respect to (i) the authorization or issuance of shares of beneficial interest ranking on a parity with or junior to our Series A preferred shares with respect to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up, whether voluntary or involuntary; or (ii) any increase, decrease or issuance of any of our Series A preferred shares or other shares of beneficial interest ranking on a parity with or junior to our Series A preferred shares with respect to the payment of distributions and the distribution of assets upon our liquidation, dissolution or winding up, whether voluntary or involuntary. Except as provided above and required by law, the holders of Series A preferred shares are not entitled to vote on any merger or consolidation involving us, on any share exchange or on a sale of all or of substantially all of our assets.

     The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which the vote would otherwise be required will be effected, all outstanding shares of Series A preferred shares have been redeemed or called for redemption and sufficient funds have been deposited in trust to effect the redemption.

     Conversion. Our Series A preferred shares are not convertible into or exchangeable for any other securities or property, except that, in limited circumstances, our Series A preferred shares may be automatically converted into or exchanged for excess shares. See “Restrictions on Ownership” above.

19

     Listing. Our Series A preferred shares are listed on the NASDAQ National Market under the symbol “IRETP.”

     Transfer Agent. We act as our own transfer agent, registrar and distribution disbursing agent with respect to our Series A preferred shares.

DESCRIPTION OF LP UNITS AND
THE AGREEMENT OF LIMITED PARTNERSHIP OF IRET PROPERTIES

     The following is a summary of the material terms of the LP Units, including a summary of certain provisions of the Agreement of Limited Partnership of IRET Properties. This summary is not a complete legal description of the LP Units and is qualified in its entirety by reference to the applicable provisions of North Dakota law and the Agreement of Limited Partnership of IRET Properties. For a comparison of the rights of holders of LP Units and our the holders of our common shares, see the section of this prospectus entitled “Comparison of Ownership of LP Units and Common Shares” beginning on Page 25.

General

     We conduct all of our day-to-day real estate activities through our operating partnership, IRET Properties. The operation of IRET Properties is governed by the Agreement of Limited Partnership of IRET Properties. We are the sole shareholder of IRET, Inc., a North Dakota corporation, which is the general partner of IRET Properties. The holders of LP Units are the limited partners of IRET Properties. As of November 30, 2004, IRET, Inc. owned approximately 76.6% of IRET Properties.

Issuance of LP Units

     We are structured as an Umbrella Partnership Real Estate Investment Trust, or UPREIT, which enables us to acquire property by issuing LP Units to a seller as a form of consideration. All LP Units have redemption rights that enable them to cause IRET Properties to redeem their LP Units for cash or, at the option of IRET, Inc., common shares on a one-for-one basis after a minimum one-year holding period. No LP Units have been registered pursuant to the federal or state securities laws and they are not listed on any exchange or quoted on any national market system. As of January 20, 2005, we had 13,075,166 LP Units outstanding, of which, in addition to the 440,758 LP Units to which this prospectus relates, 10,938,432 were also redeemable for common shares.

     IRET, Inc. is authorized, in its sole and absolute discretion and without the approval of any limited partner, to issue additional LP Units to itself, to us, to any limited partner or to any other person for such consideration and on such terms and condition as established by IRET, Inc. The issuance of LP Units to IRET, Inc. or us is subject to certain conditions. IRET, Inc. is authorized to cause IRET Properties to issue general partnership interests or LP Units for less than fair market value if IRET, Inc. has concluded in good faith that such issuance is in our best interests and in the best interests of IRET Properties. IRET, Inc. is also authorized to issue additional partnership interests in different series or classes, which may have rights and preferences that are senior to the LP Units.

Purpose, Business and Management of IRET Properties

     The purpose of IRET Properties is to conduct any business that may be lawfully conducted by a limited partnership organized pursuant to the North Dakota Uniform Limited Partnership Act, provided that such business is limited to and conducted in such a manner as to permit us at all times to qualify as a REIT. Subject to the foregoing, IRET Properties may enter into any partnership, joint venture or other similar arrangement.

     IRET, Inc., as the sole general partner, has full, exclusive and complete responsibility and discretion in the management and control of IRET Properties, and the limited partners have no authority in their capacity as limited partners to transact business for, or participate in the management activities or decisions of, IRET Properties except as otherwise required by applicable law.

Operation and Payment of Expenses

20

     The Agreement of Limited Partnership of IRET Properties requires that the partnership be operated in a manner that will enable us to satisfy the requirements for being classified as a REIT for federal tax purposes, to avoid any federal income or excise tax liability imposed by the Internal Revenue Code and to ensure that IRET Properties will not be classified as a “publicly traded partnership” for purposes of Section 7704 of the Internal Revenue Code.

     In addition to the administrative and operating costs and expenses incurred by IRET Properties, IRET Properties pays all of the administrative costs and expenses incurred by us and IRET, Inc. All of our expenses are considered expenses of IRET Properties. Our expenses generally include: (i) all expenses relating to the operation and continuity of our existence and the existence of IRET, Inc.; (ii) all expenses relating to the public offering and registration of shares of beneficial interest by us; (iii) all expenses associated with the preparation and filing of our periodic reports under federal, state or local laws or regulations; (iv) all expenses incurred by us and IRET, Inc. associated with compliance with laws, rules and regulations promulgated by any regulatory body; and (v) all other operating or administrative costs of IRET, Inc. incurred in the ordinary course of its business on behalf of IRET Properties.

Ability to Engage in Other Business; Conflict of Interest

     IRET, Inc. may have business interests and engage in business activities outside of IRET Properties, including interests and activities in direct or indirect competition with IRET Properties. IRET Properties may not purchase, sell or lease any property, borrow or loan any money, or invest in any joint ventures with any member of our board of trustees, or with any director, employee or affiliate of us, except in connection with a transaction approved by a majority of the trustees who are not in any way involved in the transaction as being a fair, competitive and commercially reasonable transaction that is no less favorable to IRET Properties than a similar transaction between unaffiliated parties under the same circumstances.

Distributions and Liquidation

     The Agreement of Limited Partnership of IRET Properties provides that IRET Properties shall distribute cash from operations on a quarterly basis, in amounts determined by IRET, Inc., in its sole discretion, to the partners in accordance with their respective percentage interests in IRET Properties. Upon liquidation of IRET Properties, and after payment of, or adequate provision for, debts and obligations, any remaining assets will be distributed to all partners with positive capital accounts in accordance with their respective positive capital account balances. If we have a negative balance in our capital account following a liquidation, we will be obligated to contribute cash equal to the negative balance in our capital account.

Allocations

     Income, gain and loss of IRET Properties for each fiscal year is allocated among the general partner and the limited partners in accordance with their respective interests, subject to compliance with the provisions of Sections 704(b) and 704(c) of the Internal Revenue Code, and the regulations issued thereunder.

Borrowing by IRET Properties

     The Agreement of Limited Partnership of IRET Properties provides that if IRET Properties requires additional funds at any time or from time to time in excess of funds available to IRET Properties from borrowing or capital contributions, IRET, Inc. may cause IRET Properties to obtain such funds from outside borrowings or IRET, Inc. may elect to borrow such funds or have us borrow such funds and subsequently lend such funds to IRET Properties on the same terms and conditions as are applicable to our or IRET, Inc.’s borrowing of such funds.

Liability of IRET, Inc. and the Limited Partners

     IRET, Inc., as the general partner of IRET Properties, is liable for all general recourse obligations of IRET Properties to the extent not paid by IRET Properties. The limited partners will only be liable to IRET Properties to

21

make payments of their capital contributions, if any. No limited partner will be liable for any debts, liabilities, contracts or obligations of IRET Properties.

Exculpation and Indemnification of IRET, Inc.

     The Agreement of Limited Partnership of IRET Properties provides that IRET, Inc. will not be responsible for losses sustained or liabilities incurred as a result of errors in judgment or from any act or omission, provided that IRET, Inc. acted in good faith. The Agreement of Limited Partnership of IRET Properties also provides for the indemnification of us, IRET, Inc., the directors, trustees, officers and employees of both us and IRET, Inc., and such other persons as IRET, Inc. may designate from time to time in its sole discretion, against liabilities relating to the operations of IRET Properties, unless it is established that (i) the act or omission of the indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty; (ii) the indemnitee actually received an improper personal benefit in money, property or service; or (iii) in the case of any criminal proceeding, the indemnitee had reasonable cause to believe that the act or omission was unlawful.

Transferability of LP Units and General Partnership Interests

     As the general partner, IRET, Inc., may not voluntarily withdraw as the general partner of IRET Properties or transfer or assign its general partnership interests in IRET Properties unless the transaction in which such withdrawal or transfer occurs results in the limited partners receiving property in an amount equal to the amount they would have received had they exercised their right to redeem their LP Units immediately prior to such transaction, or unless the successor to IRET, Inc. contributes substantially all of its assets to IRET Properties in return for an interest in IRET Properties.

     With certain limited exceptions, the limited partners may not transfer their LP Units, in whole or in part, without the written consent of IRET, Inc., which consent may be withheld in the sole discretion of IRET, Inc. IRET, Inc. may not consent to any transfer that would cause IRET Properties to be treated as a corporation for federal income tax purposes.

     IRET Properties may not engage in any transaction resulting in a change of control, unless in connection with the transaction the limited partners receive or have the right to receive cash or other property equal to the product of the number of common shares into which each LP Units is then exchangeable and the greatest amount of cash, securities or other property paid in the transaction to the holder of one common share in consideration of one such common share. If, in connection with the transaction, a purchase, tender or exchange offer is made to and accepted by the holders of more than fifty percent (50%) of the common shares, each holder of LP Units will receive, or will have the right to elect to receive, the greatest amount of cash, shares of beneficial interest or other property that such holder would have received had he, she or it exercised his, her or its right to redeem LP Units and received common shares in exchange for its LP Units immediately prior to the expiration of such purchase, tender or exchange offer and had accepted such purchase, tender or exchange offer.

     Despite the foregoing, we may merge, or otherwise combine our assets, with another entity if, immediately after such merger or other combination, substantially all of the assets of the surviving entity, other than its ownership in IRET Properties, are contributed to IRET Properties as a capital contribution in exchange for general partnership interests of IRET Properties with a fair market value, as reasonable determined by us, equal to the agreed value of the assets so contributed.

     For any transaction described in the preceding two paragraphs, we are required to use commercially reasonable efforts to structure such transaction to avoid causing the limited partners to recognize gain for federal income tax purposes by virtue of the occurrence of, or their participation in, such transaction, provided such efforts are consistent with the exercise of our trustees’ fiduciary duties under applicable law.

Fiduciary Duties

     Before becoming a limited partner, each limited partner must agree that in the event of any conflict in the fiduciary duties owed by us to our shareholders and by IRET, Inc., as the general partner of IRET Properties, to the

22

limited partners, IRET, Inc. will fulfill its fiduciary duties to such limited partners by acting in the best interests of our shareholders.

Tax Matters

     IRET, Inc. is the tax matters partner of IRET Properties and, as such, has authority to handle tax audits and to make tax elections under the Internal Revenue Code on behalf of IRET Properties and the limited partners.

Amendment of the Agreement of Limited Partnership of IRET Properties

     Any amendment to the Agreement of Limited Partnership of IRET Properties that would (i) adversely affect the right to redeem LP Units, (ii) adversely affect the limited partners’ rights to receive cash distributions, or (iii) alter the limited partnership’s allocations of capital of IRET Properties, requires the consent of the limited partners holding more than fifty percent (50%) of the LP Units held by such limited partners.

Term

     IRET Properties will continue until April 30, 2050, or until sooner dissolved upon: (i) the bankruptcy, dissolution or withdrawal of IRET, Inc.; (ii) the sale or other disposition of all or substantially all of its assets; (iii) the redemption of all of the LP Units; or (iv) the election by the general partner.

REDEMPTION OF LP UNITS

General

     Pursuant to the Agreement of Limited Partnership of IRET Properties, the limited partners have redemption rights that enable them to cause IRET Properties to redeem their LP Units for cash or, at the option of IRET, Inc., common shares on a one-for-one basis after a minimum one-year holding period. The redemption price will be paid in cash in the event that the issuance of common shares would: (i) result in any person owning, directly or indirectly, common shares in excess of the ownership limitation of 50% of the outstanding Shares; (ii) result in Shares being owned by fewer than 100 persons; (iii) result in us being “closely held” within the meaning of Section 856(h) of the Code; (iv) cause us to own, actually or constructively, 10% or more of the ownership interest in a tenant of our or IRET Properties’ real estate, within the meaning of Section 856(d)(2)(B) of the Internal Revenue Code; or (v) cause the acquisition of common shares by such redeeming holder of LP Units to be “integrated” with any other distribution of common shares for purposes of complying with the Securities Act of 1933.

     The limited partners may exercise the redemption at any time after the first anniversary of the date of acquisition of LP Units, provided that the limited partner is not subject to any other restrictions relating to the redemption of LP Units. Redemption rights are exercised pursuant to a notice of exchange delivered by the holder of LP Units to IRET Properties. No limited partner will be permitted more than two redemptions during any calendar year and no redemption may be made for less than 1,000 LP Units or, if such limited partner owns less than 1,000 LP Units, all of the LP Units held by such limited partner.

     The number of common shares issuable upon redemption of LP Units will be adjusted upon the occurrence of share splits, mergers, consolidations or similar pro rata share transactions, which otherwise would have the effect of diluting the ownership interest of the limited partners or our shareholders.

Tax Treatment of Redemption of LP Units

     The following discussion summarizes certain federal income tax considerations that may be relevant to a holder of LP Units that exercises his, her or its right to redeem LP Units.

     The Agreement of Limited Partnership of IRET Properties provides that the redemption of LP Units will be treated by us, IRET Properties and the redeeming holder of LP Units as a sale of LP Units by such holder to us. Such sale will be fully taxable to the redeeming holder of LP Units.

23

     The determination of gain or loss from the sale or other disposition will be based on the difference between the amount realized for tax purposes by the redeeming holder of LP Units and his, her or its tax basis in such LP Units. The amount realized will be the sum of the fair market value of property received (e.g., the common shares) by the holder plus the portion of the liabilities of IRET Properties that was allocable to the redeemed LP Units. In general, the tax basis of a holder of LP Units is the holder’s initial basis in the LP Units – the adjusted basis of the property contributed for the LP Units plus any cash contributed for the LP Units, reduced by any liabilities assumed by IRET Properties and increased by the holder’s share of IRET Properties’ liabilities – and then is increased to reflect the redeeming holder’s allocable share of income of IRET Properties and decreased, but not below zero, to reflect the redeeming holder’s allocable share of loss and distributions of IRET Properties. The basis also can change based on changes in the holder’s share of liabilities of IRET Properties. To the extent that the amount realized exceeds the redeeming holder’s basis for the redeemed LP Units, such redeeming holder will recognize gain. It is possible that the amount of gain recognized or even the tax liability resulting from such gain could exceed the fair market value of the Shares received upon redemption. Each redeeming holder of LP Units should consult with his, her or its own tax advisor for the specific tax consequences resulting from redemption of LP Units.

     Generally, any gain recognized upon a sale or other disposition of LP Units will be treated as gain attributable to the sale or disposition of a capital asset. To the extent that money or property received by a holder in exchange for all or part of his LP Units is attributable to the redeeming holder’s share of “unrealized receivables” and inventory items of IRET Properties (as defined in Section 751 of the Internal Revenue Code), the gain or loss is ordinary income or loss. Unrealized receivables include, to the extent not previously included in the income of IRET Properties, any rights to payment for services rendered or to be rendered. Unrealized receivables also include amounts that would be subject to recapture as ordinary income if IRET Properties had sold its assets at their fair market value at the time of the transfer of LP Units.

     For individuals, trusts and estates, the maximum rate of tax on the net capital gain from a sale or exchange of a long-term capital asset (i.e., a capital asset held for more than 12 months) is 15%. The maximum rate for net capital gains attributable to the sale of depreciable real property held for more than 12 months is 25% to the extent of the prior depreciation deductions for “unrecaptured Section 1250 gain” (that is, depreciation deductions not otherwise recaptured as ordinary income under the existing depreciation recapture rules). Treasury Regulations provide that individuals, trusts and estates are subject to a 25% tax, or the “25% Amount”, to the extent of their allocable share of unrecaptured Section 1250 gain immediately prior to their sale or disposition of the LP Units. (A 28% rate, which applies to gains on certain collectibles and the excludable gain on the sale of qualified small business stock held for more than five years, is unlikely to be applicable to IRET Propertise’ gains.) Provided that the LP Units are held as a long-term capital asset, such redeeming holder’s LP Units would be subject to a maximum rate of tax of 15% of the difference, if any, between any gain on the sale or disposition of the LP Units and the 25% Amount.

     There is a risk that a redemption by IRET Properties of LP Units issued in exchange for a contribution of property to IRET Properties may cause the original transfer of property to IRET Properties in exchange for LP Units to be treated as a “disguised sale” of property. Section 707 of the Internal Revenue Code and the Treasury Regulations thereunder, commonly referred to as the Disguised Sale Regulations, generally provide that, unless one of the prescribed exceptions is applicable, a partner’s contribution of property to a partnership and a simultaneous or subsequent transfer of money or other consideration (which may include the assumption of or taking subject to a liability) from the partnership to the partner will be presumed to be a sale, in whole or in part, of such property by the partner to the partnership. Further, the Disguised Sale Regulations provide generally that, in the absence of an applicable exception, if money or other consideration is transferred by a partnership to a partner within two years of the partner’s contribution of property, the transactions are presumed to be a sale of the contributed property unless the facts and circumstances clearly establish that the transfers do not constitute a sale. The Disguised Sale Regulations also provide that if two years have passed between the transfer of money or other consideration and the contribution of property, the transactions will be presumed not to be a sale unless the facts and circumstances clearly establish that the transfers constitute a sale. Each redeeming holder of LP Units should consult with his, her or its own tax advisor to determine whether a redemption of LP Units could be subject to the disguised sale regulations.

CERTAIN TAX CONSIDERATIONS

Considerations Regarding IRET and its Shareholders.

     Federal Income Taxation. Since our organization, we have operated in a manner intended to qualify us as a REIT under sections 856-858 of the Internal Revenue Code. Under these sections of the Internal Revenue Code, a REIT that meets certain requirements will not be subject to Federal income tax with respect to income that it distributes to its shareholders. Rather, all such income will be taxed at the shareholder level. In order to be considered a REIT for purposes of the Federal income tax laws, we must continue to meet the requirements of those sections of the Internal Revenue Code, including the following:

     As a REIT, we will not be taxed on that portion of our taxable income that is distributed to our shareholders, provided that at least 90% of our taxable income is distributed. To the extent that there is undistributed taxable income or undistributed capital gain income, we will be taxed as a domestic corporation at corporate income tax rates. However, we may retain some or all of our net capital gain without incurring double taxation. If we elect to do this, we are taxed on the amount we designate as retained capital gain at the capital gains rate generally applicable to corporations. Our shareholders then must include in their income their proportionate share of the undistributed capital gain as long-term capital gain. In this case the shareholder is deemed to have paid the shareholder’s share of the tax we paid, and is entitled to a credit for this amount on the shareholder’s income tax

35

return. In addition, the shareholder’s basis in the shareholder’s shares of beneficial interest is increased by the amount of the undistributed long-term capital gains taxed to the shareholder, less the amount of capital gains tax we paid on those capital gains. As a REIT, we will not be entitled to carry back or carry forward any net operating losses with respect to the income taxed to us. So long as we have met the statutory requirements for taxation as a REIT, distributions made to our shareholders will be taxed to such shareholders in the manner described below.

     If we do not qualify as a REIT for any taxable year, we will be taxed as a domestic corporation, and we will not be able to deduct distributions to our shareholders in computing our taxable income. Such distributions, to the extent made out of our current or accumulated earnings and profits, will be taxable to the shareholders as dividends, but will be eligible for the dividends received deduction for corporations.

     In the opinion of the law firm of Pringle & Herigstad, P.C., we have conducted our operations in such a manner as to qualify as a REIT. Treasury Regulations issued under the Internal Revenue Code require that the members of our board of trustees have continuing exclusive authority over our management, the conduct of our affairs and, with certain limitations, the management and disposition of the property we own. Our board of trustees intends to adopt any amendments to our Third Restated Declaration of Trust that may be necessary in order for us to continue to operate as a REIT. Any amendments to our Third Restated Declaration of Trust that are required in order for us to remain qualified as a REIT may be made by the board of trustees without notice to, or a vote of, our shareholders.

     Taxation of Our Shareholders. Distributions made to our shareholders out of current or accumulated earnings and profits will be taxed to our shareholders as ordinary income. (The portion of our distributions that may constitute “qualified dividends” eligible for tax at a maximum rate of 15% is limited. To the extent a portion qualifies, we will inform our shareholders of that fact in a written notice mailed within 60 days of the close of our tax year.) Distributions that are designated as capital gain dividends will generally be taxed as long-term capital gains to the extent they do not exceed our actual net capital gain income for the taxable year. Distributions to a shareholder in excess of current or accumulated earnings and profits will be treated as a nontaxable return of capital to the extent that they do not exceed the adjusted basis of a shareholder’s securities. If distributions in excess of current or accumulated earnings and profits exceed the adjusted basis of a shareholder’s shares of beneficial interest, the distributions will be included in the shareholder’s income as long-term or short-term capital gain (assuming the shares of beneficial interest are held as a capital asset in the hands of the shareholder). So long as we are taxed as a REIT distributions will not be eligible for the dividends received deduction for corporations.

     We will notify shareholders at the end of each year as to the portions of the distributions that constitute ordinary income, qualified dividends, net capital gain or return of capital. We will also inform shareholders of the portions of any capital gains distributions that are 15%-rate capital gain distributions, 25%-rate capital gain distributions (unrecaptured section 1250 gain distributions), and, if any, 28%-rate gain distributions (certain gains on collectibles and the excludable gain on the sale of qualified small business stock held for more than five years). Any dividend declared by us during the months of October, November or December of any year payable to a shareholder of record on a specified date in any such month will be treated as both paid by us and received by the shareholder on December 31 of such year, even though the dividend may not actually be paid by us until January of the following calendar year. The shareholders may not include in their individual income tax returns any of our operating or extraordinary losses, whether ordinary or capital.

     In addition, as described earlier, if we retain some or all of our net capital gain and elect to avoid double tax on these gains, we will be taxed on the amount so designated at the capital gains rate generally applicable to corporations. A shareholder then must include the shareholder’s proportionate share of these undistributed capital gains in income as long-term capital gain. The shareholders are deemed to have paid their share of the tax we paid, and they may claim a credit for this amount on their income tax returns. In addition, the tax on the shareholder’s shares of beneficial interest is increased by the amount of such undistributed long-term capital gains taxed to the shareholder, less the amount of capital gains tax we paid on those capital gains.

     In general, any gain or loss upon a sale or exchange of our securities by a shareholder who has held such securities as a capital asset will be long-term or short-term, depending on whether the securities were held for more than one year; provided, however, that any loss on the sale or exchange of our securities that have been held for six months or less by a shareholder that is an individual, an estate, or a trust will be treated as a long-term capital loss to

36

the extent that distributions from us are required to be treated by such shareholders as long-term capital gain or are qualified dividends taxable at a maximum rate of 15%.

     State and Local Income Taxation. Since we qualify as a REIT for purposes of the Federal income tax laws, we generally are not subject to state income tax on that portion of our taxable income that is distributed to our shareholders. Shareholders, however, may be subject to taxation on distributions we make to them depending on the state or local jurisdiction of residence of the shareholder. Prospective shareholders should consult their tax advisors for an explanation of how state and local tax laws could affect their investment.

     Taxation of Pension and Profit Sharing (including 401(k)) Trusts, IRAs and other Tax-Exempt Entities. Amounts distributed as dividends by a qualified REIT generally do not constitute unrelated business taxable income, or UBTI, when received by a tax-exempt entity. As a consequence, the dividend income received from us by a tax-exempt entity, including a qualified pension or profit sharing (including a 401(k)) trust or an IRA, should not be UBTI to the tax-exempt entity provided that: (a) the tax-exempt entity has not held its securities as “debt-financed property” within the meaning of the Internal Revenue Code, and (b) the securities are not otherwise used in an unrelated trade or business of the tax-exempt entity. If we are considered a “pension-held REIT,” an additional requirement must be satisfied in order for dividend income received by a tax-exempt entity that is a qualified pension or profit sharing (including 401(k)) trust, or a qualified trust, not to be UBTI. This requirement is that a qualified trust may not hold more than 10% by value of the interests in us. In general, a REIT is considered a “pension-held REIT” if it takes advantage of a special rule in the Internal Revenue Code permitting it to satisfy the “five or fewer individual ownership requirement” mentioned above in subparagraph (iii) of the subsection entitled “—Considerations Regarding IRET and its Shareholders” by treating beneficiaries of a qualified trust as owners, and the REIT is considered to be “predominantly held” by qualified trusts. A REIT is considered to be “predominantly held” by qualified trusts if: (a) at least one qualified trust holds more than 25% by value of the interests in the REIT; or (b) one or more qualified trusts, each of which own more than 10% by value of the interests in the REIT, hold in the aggregate more than 50% by value of the interests in the REIT.

     With respect to tax-exempt entities that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts and qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (9), (17) and (20) of the Internal Revenue Code, respectively, income from an investment in us will constitute UBTI unless the organization is able to deduct amounts set aside or placed in reserve for certain purposes so as to offset the income generated by its investment in us. Such prospective investors should consult their tax advisors concerning these “set-aside” and reserve requirements.

     Reporting to the IRS and Backup Withholding. We will report to our shareholders and the Internal Revenue Service the amount of dividends paid during each calendar year and the amount of tax withheld, if any. Under the backup withholding rules, a shareholder may be subject to backup withholding, currently at the rate of 28%, with respect to dividends paid, unless such holder: (i) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or (ii) provides a correct taxpayer identification number, certifies that he or she is exempt from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A shareholder that does not provide us with a correct taxpayer identification number may be subject to penalties imposed by the Internal Revenue Service. Any amount paid as backup withholding will be creditable against the shareholder’s income tax liability. In addition, we may be required to withhold a portion of capital gain distributions to any shareholder who fails to certify its non-foreign status to us.

Tax Treatment of IRET Properties and Its Limited Partners.

     The following discussion summarizes certain federal income tax considerations applicable to IRET’s investment in IRET Properties. The discussion does not cover state or local tax laws or any federal tax laws other than income tax laws.

     We will include in our income our share of IRET Properties’ income and deduct our share of IRET Properties’ losses only if IRET Properties is classified for federal income tax purposes as a partnership, rather than as a corporation, an association taxable as a corporation or a “publicly traded partnership” within the meaning of the federal income tax laws.

37

     We have not requested, and do not intend to request, a ruling from the Internal Revenue Service that IRET Properties will be classified as a partnership for federal income tax purposes. Instead, based on certain factual assumptions and representations we have made and on currently applicable Treasury Regulations under Section 7701 of the Internal Revenue Code, Pringle & Herigstad, P.C., is of the opinion that IRET Properties will be treated for federal income tax purposes as a partnership. Further, based on certain factual assumptions and representations we have made, Pringle & Herigstad, P.C., is of the opinion that IRET Properties will not be a publicly traded partnership. Unlike a tax ruling, an opinion of counsel is not binding upon the Internal Revenue Service, and no assurance can be given that the Internal Revenue Service will not challenge the status of IRET Properties as a partnership for federal income tax purposes. If a court sustained such a challenge, IRET Properties would be treated as a corporation for federal income tax purposes, as described below. In addition, the opinion of Pringle & Herigstad, P.C., is based on existing law. No assurance can be given that administrative or judicial changes would not modify the conclusions expressed in the opinion.

     If for any reason IRET Properties was taxable as a corporation, rather than a partnership, for federal income tax purposes, we would not be able to qualify as a REIT. In addition, any change in the IRET Properties’ status for tax purposes might be treated as a taxable event, in which case we might incur a tax liability without any related cash distribution. Further, items of income and deduction of IRET Properties would not pass through to its partners, and its partners would be treated as shareholders for tax purposes. Additionally, IRET Properties would be required to pay income tax at corporate tax rates on its net income, and distributions to its partners would constitute dividends that would not be deductible in computing IRET Properties’ taxable income.

Income Taxation of IRET Properties and its Partners.

     Partners, Not IRET Properties, Subject to Tax. A partnership is not a taxable entity for Federal income tax purposes. As such, we will be required to take into account our allocable share of income, gains, losses, deductions and credits from IRET Properties for any taxable year ending within, or with, our taxable year, without regard to whether we have received, or will receive, any distributions.

     Partnership Allocation of Income, Losses and Capital Gain. Although a partnership agreement generally will determine how allocations of income and losses are made among partners, such allocations will be disregarded for tax purposes under Section 704(b) of the Internal Revenue Code if they do not comply with the provisions of Section 704(b) of the Internal Revenue Code and the Treasury Regulations promulgated thereunder. If an allocation is not recognized for Federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the partners’ interests in the partnership, which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. IRET Properties’ allocations of taxable income and loss are intended to comply with the requirements of Section 704(b) of the Internal Revenue Code and the Treasury Regulations promulgated thereunder.

     Tax Allocations with Respect to Contributed Property. Pursuant to Section 704(c) of the Internal Revenue Code, income, gain, loss and deductions that are attributable to appreciated or depreciated property contributed to a partnership in exchange for an interest in the partnership must be allocated for Federal income tax purposes in a manner such that the contributor is charged with, or benefits from, the unrealized gain or unrealized loss associated with the property at the time of the contribution. The amount of such unrealized gain or unrealized loss is generally equal to the difference between the fair market value of the contributed property at the time of contribution and the adjusted tax basis of such property at the time of contribution. The Treasury Department has issued regulations requiring partnerships to use a “reasonable method” for allocating items affected by Section 704(c) of the Internal Revenue Code, and outlining several reasonable allocation methods. IRET Properties plans to elect to use the traditional method for allocating under section 704(c) items with respect to the properties it acquires in exchange for limited partnership units.

     Under the limited partnership agreement of IRET Properties, depreciation or amortization deductions will be allocated among the partners in accordance with their respective interests. In addition, gain on the sale of a property contributed to IRET Properties by a limited partner in exchange for limited partnership units will be specially allocated to such limited partner to the extent of any built-in gain with respect to the property. Depending on the allocation method elected under section 704(c), it is possible that: (i) we may be allocated lower amounts of depreciation deductions for tax purposes with respect to contributed properties than would be allocated to us if such properties were to have a tax basis equal to their fair market value at the time of contribution, and (ii) we may be

38

allocated taxable gain in the event of a sale of such contributed properties in excess of the economic profit allocated to us as a result of such sale. These allocations may cause us to recognize taxable income in excess of cash proceeds, which may adversely affect our ability to comply with the REIT distribution requirements. This situation has not occurred in the past, and we do not currently have any reason to believe it will occur in the future.

     The allocation rules also may affect the calculation of our earnings and profits for purposes of determining the portion of our distributions that are taxable as a dividend. The allocations described in this paragraph may result in a higher portion of our distributions being taxed as a dividend than would have occurred had we purchased the properties for cash.

     Tax Basis in IRET Properties. In general, our adjusted tax basis of our partnership interest in IRET Properties is equal to: (i) the amount of cash and the basis of any other property that we contribute to IRET Properties (including the value of our shares issued in exchange for converted IRET Properties interests acquired by us upon a redemption), (ii) increased by our share of income and indebtedness, and (iii) reduced, but not below zero, by our share of the loss and the amount of cash and the basis of any other property distributed to us.

     If the allocation of our share of loss would reduce the adjusted tax basis of our partnership interest in IRET Properties below zero, the recognition of such loss will be deferred until such time as the recognition of such loss would not reduce our adjusted tax basis below zero. To the extent that cash distributions, or any decrease in our share of the indebtedness, would reduce our adjusted tax basis below zero, the excess distributions (after our adjusted tax basis has been reduced to zero) will constitute taxable income to us. Such income normally will be characterized as capital gain, and, if our partnership interest in IRET Properties has been held for longer than the long-term capital gain holding period, the income will constitute long-term capital gain.

     Sale of Real Estate. Generally, any gain realized by IRET Properties on the sale of property held for more than one year will be long-term capital gain, except for any portion of such gain that is treated as depreciation or cost recovery recapture.

     Any gain recognized on the disposition of a particular property contributed by a partner in exchange for limited partnership will be allocated first to such contributing partner under Section 704(c) of the Internal Revenue Code to the extent of such contributing partner’s built-in gain. Any remaining gain will be allocated among the partners in accordance with their ownership percentage interests in IRET Properties.
