Portfolio Operating Performance and Same Community Results

Non-Mature Properties

2

The composition of the Company’s portfolio has changed significantly over the past three years. Currently, 19% of the portfolio is considered ‘non-mature’, meaning that the communities have not been owned or stabilized for at least one year. In the coming quarters, the Same Community portfolio will benefit from an influx of acquired properties currently considered non-mature in California, Metropolitan Washington D.C. and Florida, which are high rent and high occupancy markets. These high barrier markets comprise approximately 76% of non-mature NOI. The overall average monthly rental rate of our non-mature assets is approximately $300 above the current mature portfolio.

Portfolio Repositioning

As previously announced, the Company acquired 11 communities with 3,761 apartment homes for a total purchase price of $529 million (averaging $140,500 per home) during the quarter, which included seven communities in the Essex transaction. These transactions represent a blended capitalization rate of 5.6% using forward twelve months of operations and a reserve for capital expenditures ranging from $270 to $450 per home.

During the fourth quarter, the Company announced sales totaling $112 million (averaging $48,000 per home) at a blended capitalization rate of 8.7% using trailing twelve months of operations less an actual capital expenditure reserve of $470 per home and an implied management fee of 2.75%. The sales include eight communities in Michigan with 1,970 apartment homes for a total of $91.5 million (averaging $46,400 per home), and one community in Louisville, Kentucky for $20.1 million (averaging $56,600 per home). In addition, the Company sold nine acres of land in Texas for $0.8 million. The Company recognized $17.7 million in gains on the sales in the fourth quarter. The Company is under contract to sell 11 communities consisting of 2,623 units for $169 million at a blended cap rate of 5.5%. The communities are located in Houston, Anaheim and Phoenix.

For more details on the Company’s acquisition and disposition activities, see our press release dated December 13, 2004.

“These transactions continue to move us forward on two fronts. Approximately 50% of our projected 2005 NOI is expected to come from California, Florida and the Metro D.C. area, and we have exited two additional markets, bringing our total to 43,” stated W. Mark Wallis, Senior Executive Vice President, Strategy, Legal, Acquisitions, Dispositions & Development.

Financing Activities

In October, the Company issued $100 million of 5.00% senior unsecured notes due January 15, 2012 at spread of 123 basis points. Also in October, the Company issued $25 million of 4.30% senior unsecured notes due July 1, 2007 at spread of 100 basis points. These notes represent a re-opening of the 4.30% senior notes issued on June 25, 2004. These additional notes will constitute a single series of notes, bringing the aggregate principal amount outstanding of the 4.30% senior notes to $75 million. In November, the Company issued $100 million of 5.25% senior unsecured notes due January 15, 2015 at a spread of 127 basis points. During the quarter, the Company issued 4.5 million shares of common stock at a price of approximately $20.48 per share and received net proceeds of $91.3 million.

eBay Purchase of Rent.com

On December 16, 2004, eBay (Nasdaq: EBAY) announced that it had agreed to acquire privately held Rent.com, a leading Internet listing web site in the apartment and rental housing industry, for approximately $415 million plus acquisition costs, net of Rent.com’s cash on hand. United Dominion owns shares in Rent.com. The acquisition, which is subject to various regulatory approvals and approval of Rent.com’s stockholders, is expected to close in the first quarter of 2005.

If the closing occurs, the Company expects to record a one-time pre-tax gain of between $12 and $14 million. There is no assurance that the Rent.com transaction will close, or if it does, whether the Company will realize the anticipated gain. The Company is considering, among other things, utilizing a portion of the gain to offset prepayment penalties we may elect to incur by prepaying certain secured debt. The earnings guidance shown below does not include the possible effects of the Rent.com transaction.

Earnings Guidance

United Dominion believes that the financial results for 2005 will be affected by international, national and regional economic trends and events, the acquisition and/or disposition of apartment communities and other factors. The Company’s guidance for the first quarter 2005 FFO is $0.37 to $0.39 per share (diluted) and $1.57 to $1.70 per share (diluted) for the full year 2005. All guidance is based on the current expectations and judgment of the Company’s management team.

Detailed assumptions for the Company’s 2005 guidance can be found on our website at:
http://media.corporate-ir.net/media_files/irol/11/112440/guidance/guidance2005.pdf

A reconciliation of the range provided for projected 2005 FFO per share for the full year to Earnings Per Share (“EPS”) for the full year is as follows:

	2005
	High-end			Low-end
Funds From Operations(1)	$	1.70		$	1.57
Conversion to GAAP Share Count (2)		0.22			0.21
Minority Interest of OP Unit Holders (2)		(0.02	)		(0.04	)
Depreciation (3)		(1.58	)		(1.48	)
Gains (3)		0.15			0.30
Preferred Dividends		(0.07	)		(0.07	)
Expected Earnings Per Share	$	0.40		$	0.49

(1) The National Association of Real Estate Investment Trusts (“NAREIT”) defines funds from operations (“FFO”) (April 2002 White Paper) as net income (computed in accordance with accounting principles generally accepted in the United States (GAAP)), excluding gains (or losses) from sales of depreciable property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. The Company believes that

FFO is helpful to investors as a supplemental measure of the operating performance of a real estate company because it provides investors an understanding of the ability of the Company to incur and service debt and to make capital expenditures. FFO in and of itself does not represent net income or net cash flows from operating activities in accordance with GAAP. Therefore, FFO should not be exclusively considered as an alternative to net income or to net cash flows from operating activities as determined by GAAP or as a measure of liquidity.
(2) Operating Partnership units are not considered to be common stock equivalents for GAAP purposes.
(3) Due to the uncertain timing and extent of property dispositions and acquisitions, actual results could differ materially from expected EPS.

FFO is defined as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable property, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. This definition conforms with the National Association of Real Estate Investment Trust’s definition issued in April 2002. United Dominion considers FFO in evaluating property acquisitions and its operating performance and believes that FFO should be considered along with, but not as an alternative to, net income and cash flows as a measure of United Dominion’s activities in accordance with generally accepted accounting principles and is not necessarily indicative of cash available to fund cash needs.

For the three months ended December 31, 2004 and 2003, distributions to preferred stockholders exclude $1.0 million and $0.9 million, respectively, related to premiums on preferred stock conversions. For the twelve months ended December 31, 2004 and 2003, distributions to preferred stockholders exclude $5.7 million and $19.3 million, respectively, related to premiums on preferred stock conversions.

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.

	Three Months Ended					Twelve Months Ended
	December 31,					December 31,
In thousands	2004			2003		2004			2003

Gains from the disposition of real estate developed for sale	$	1,202		$	—	$	1,202		$	812

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.
