(To Prospectus dated June 9, 2004 and Prospectus Supplement
dated June 17, 2004, as supplemented by a Supplement dated September 29, 2004)

UNITED DOMINION REALTY TRUST, INC.
Medium-Term Notes Due Nine Months or More From Date of Issue

Fixed Rate Notes

The Notes are not Discount Notes.

     “N/A” as used herein means “Not Applicable.” “A/S” as used herein means “As stated in the Prospectus Supplement dated June 17, 2004, as supplemented by a Supplement dated September 29, 2004.”

     These notes represent a reopening of the 5.25% medium-term notes due 2015 issued by United Dominion Realty Trust, Inc., and these notes constitute a single series of notes with those notes, bringing the aggregate principal amount of the notes outstanding to $250 million.

     Pursuant to U.S. Treasury regulations section 1.1275-2(k)(3), the issuance of the notes will be treated as a “qualified reopening” of the fixed rate notes with an original issue date of November 1, 2004 (the “original notes”). Therefore, for purposes of the rules governing original issue discount, the notes will have the same issue date, issue price and adjusted issue price as the original notes. See “U.S. Federal Income Tax Consequences — U.S. Holders — Original Issue Discount” in the prospectus supplement dated June 17, 2004. Depending on your purchase price for your notes, your notes may have a market discount or amortizable bond premium. See “U.S. Federal Income Tax Consequences — U.S. Holders — Market Discount” and “— Acquisition Premium; Amortizable Bond Premium” in the prospectus supplement dated June 17, 2004. The purchase price for the notes will also reflect interest accrued from November 1, 2004 (“pre-issuance accrued interest”), which will be included in the accrued interest to be paid on the first interest payment date on July 15, 2005. In accordance with U.S. Treasury regulations section 1.1273-2(m), for purposes of the rules governing original issue discount, United Dominion Realty Trust, Inc. will exclude the pre-issuance accrued interest from the issue price of the notes. In accordance with this treatment, holders must treat a corresponding portion of the interest payable on the first interest payment date as a return of the excluded pre-issuance accrued interest, rather than as an amount payable on the notes.

     United Dominion Realty Trust, Inc., sometimes referred to herein as the “Company,” may redeem all or part of the notes at any time at its option at a redemption price equal to the greater of (1) the principal amount of the notes being redeemed plus accrued and unpaid interest to the redemption date or (2) the Make-Whole Amount for the notes being redeemed.

     “Make-Whole Amount” means, as determined by the Quotation Agent, the sum of the present values of the principal amount of the notes to be redeemed, together with the scheduled payments of interest (exclusive of interest to the redemption date) from the redemption date to the maturity date of the notes being redeemed, in each case discounted to the redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued and unpaid interest on the principal amount of the notes being redeemed to the redemption date.

     “Adjusted Treasury Rate” means, with respect to any redemption date, the sum of (x) either (1) the yield for the maturity corresponding to the Comparable Treasury Issue, under the heading that represents the average for the immediately preceding week, appearing in the most recent published statistical release designated “H.15 (519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities” (provided, if no maturity is within three months before or after the remaining term of the notes being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounded to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third business day preceding the redemption date, and (y) .20%.

     “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the notes being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes being redeemed.

     “Comparable Treasury Price” means, with respect to any redemption date, (x) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations so obtained or (y) if fewer than five Reference Treasury Dealer Quotations are so obtained, the average of all such Reference Treasury Dealer Quotations so obtained.

     “Quotation Agent” means the Reference Treasury Dealer selected by the indenture trustee after consultation with United Dominion Realty Trust, Inc.

     “Reference Treasury Dealer” means any of J.P. Morgan Securities Inc., Goldman, Sachs & Co., their respective successors and assigns and three other nationally recognized investment banking firms selected by United Dominion Realty Trust, Inc. that are primary U.S. Government securities dealers.

     “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the indenture trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the indenture trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

The following is a reconciliation of GAAP gains from the disposition of real estate developed for sale to gross gains from the disposition of real estate developed for sale.

Gains from the disposition of real estate investments developed for sale is defined as net sales proceeds less a tax provision (such development by REITs must be conducted in a TRS) and the gross investment basis of the asset before accumulated depreciation. We consider FFO with gains/losses on real estate developed for sale to be a meaningful supplemental measure of performance because the short-term use of funds produce a profit which differs from the traditional long-term investment in real estate for REITs.

The following is a reconciliation of FFO share information to weighted average common shares outstanding, basic and diluted, reflected in the statements of operations information for the three months ended March 31, 2005 and 2004.
