                  APARTMENT INVESTMENT AND MANAGEMENT COMPANY
                             ANNOUNCES 2003 OUTLOOK

DENVER, COLORADO, December 19, 2002

    Apartment Investment and Management Company (NYSE: AIV) ("Aimco") announced
today its Outlook for the fourth quarter and full year 2002 and full year 2003.
Aimco will host a live Webcast on January 9, 2003 at noon EST, at which time
management will provide further details of Aimco's 2003 operating plan. The
Webcast will be available live and for replay through Aimco's Website at:
Aimco.com/about/03Outlook.asp.

FOURTH QUARTER AND FULL YEAR 2002

    Aimco expects fourth quarter and full year 2002 financial results to be
within the range of results projected in the Outlook Summary dated November 4,
2002 (Schedule XII of the Earnings Release Supplement). The high end of expected
results has been reduced by $0.04 per share due principally to lower net
transaction income. With this adjustment, Aimco expects:

    - Funds From Operations ("FFO") for the fourth quarter and full year 2002 to
      be $1.04 to $1.10 and $4.63 to $4.69 per share, respectively.

    - Adjusted Funds From Operations ("AFFO") for the fourth quarter and full
      year 2002 to be $0.86 to $0.92, and $3.80 to $3.86 per share,
      respectively.

    - "Same Store" net operating income to decline 5% to 6% in the fourth
      quarter compared with the same period last year, and "Same Store" net
      operating income to decline 2.0% to 2.5% for 2002 compared with 2001.

2003 OUTLOOK

    Aimco has assumed a range of results for its 2003 Outlook. The range is
based on the uncertain timing of an economic recovery and, specifically,
associated apartment demand. The lower end of Aimco's Outlook assumes economic
conditions unchanged from the fourth quarter of 2002. In this scenario, "Same
Store" revenue remains flat with no assumed changes in occupancy and rent from
the fourth quarter 2002, and results in a decline in net operating income (NOI)
of approximately 4% for 2003 compared with 2002. The upper end of Aimco's
Outlook also assumes no economic recovery but does include seasonal increases in
"Same Store" occupancy, which ranges from 91% to 93% during the year and
averages 92%, and results in a 1% decline in NOI for 2003 compared with 2002.

(1) Per share data are non-GAAP measures commonly used in addition to EPS, which
    is a financial reporting measure under GAAP. FFO and AFFO per share should
    not be considered substitutes to GAAP measures as indicators of Aimco's
    performance. GAAP EPS projections will be available in the first quarter
    2003.

(2) See 2003 Outlook Assumptions schedule under Operating FFO Assumptions for
    detail.

(3) See 2003 Outlook Assumptions schedule under Transaction FFO Assumptions for
    detail.

(4) Due to anti-dilutive adjustments, the share count used for AFFO is lower
    than for FFO.

(5) Dividends are determined and declared by the Board of Directors on a
    quarterly basis. For purposes of this 2003 Outlook Summary, we have assumed
    no change in the common share dividend.

(6) The payout ratio is based on AFFO before capital enhancements, which are
    discretionary expenditures.
