Item 5.02   Departures  of Directors or Principal  Officers;  Election of
            Directors; Appointment of Principal Officers.

On  July  14,  2005,  Apartment  Investment  and  Management  Company  ("Aimco")
announced the  appointment  of Robert Y. Walker IV as senior vice  president and
chief accounting  officer  effective January 2006. Mr. Walker will also serve as
chief  accounting  officer of the  Partnership's  general partner (the "Managing
General Partner"). Mr. Walker will join Aimco as senior vice president on August
1, 2005.

As previously announced,  Thomas M. Herzog, the current chief accounting officer
of Aimco and the Managing General Partner,  will be succeeding Paul McAuliffe as
chief  financial  officer in January  2006 when Mr.  McAuliffe  assumes a senior
advisory role as an executive vice president supporting Aimco in various capital
markets  activities.  Mr.  Herzog has served as senior vice  president and chief
accounting  officer of Aimco  since  January  2004 and of the  Managing  General
Partner since February 2004.

Mr. Walker,  39, is a certified public  accountant.  Since June 2002, Mr. Walker
has been senior vice  president  and chief  financial  officer at Miller  Global
Properties,  LLC, a  Denver-based  private  equity,  real estate  fund  manager.
Through its six real estate funds, Miller Global Properties, LLC has acquired or
developed over 70 office and hotel  investments in the United States and Europe.
From May 1997 to June 2002,  Mr.  Walker was employed by GE Capital Real Estate,
serving as global  controller  in  Stamford,  Connecticut  from May 2000 to June
2002.  None of the  companies  where Mr.  Walker has worked in the previous five
years is a parent,  subsidiary  or other  affiliate  of the  Partnership  or its
Managing  General  Partner.  Mr.  Walker  has no  family  relationship  with any
director,   executive  officer,  or  any  person  nominated  or  chosen  by  the
Partnership  or its Managing  General  Partner to become a director or executive
officer of the Partnership or its Managing General Partner.

Aimco has  agreed to pay Mr.  Walker a base  salary of  $250,000  per year and a
performance bonus, which is guaranteed to be at least $250,000 in 2005 and 2006.
On the date Mr. Walker begins  employment with Aimco, he will receive two grants
of  restricted  stock.  The first  grant  will be a number  of  shares  equal to
$250,000  divided by the average  closing price of Aimco common stock on the New
York Stock Exchange over the 30 trading days immediately prior to his start date
(the "Average  Price").  The first grant of  restricted  shares will vest on the
one-year  anniversary  of the start date.  The second  grant will be a number of
shares equal to $500,000  divided by the Average Price.  The  restricted  shares
will vest annually over five years - 20% on each  anniversary of the grant date,
beginning  with the first  anniversary.  If Mr.  Walker is  terminated  by Aimco
(other than for cause) then the vesting of the restricted shares will accelerate
and all unvested shares will become  immediately  vested. If, during the vesting
period,  Aimco terminates Mr. Walker for cause or he voluntarily  terminates his
employment with Aimco for any reason,  he will immediately  forfeit all unvested
restricted  shares.  During the vesting  period,  Mr. Walker will be entitled to
dividends on the  restricted  shares.  He will also  receive an incentive  stock
option to purchase  the same number of shares as are subject to the second grant
of restricted  stock,  at an exercise  price equal to the closing price of Aimco
common stock on the last business day immediately prior to his start date. These
options  will vest  annually  over five years - 20% on each  anniversary  of the
grant  date,  beginning  with the first  anniversary.  Except  for Mr.  Walker's
currently proposed  employment  arrangements,  since January 1, 2004, there have
not been any transactions, nor are there any currently proposed transactions, to
which the Partnership or its Managing General Partner or any of its subsidiaries
was or is to be a party,  in which the amount  involved  exceeds  $60,000 and in
which Mr. Walker had, or will have, a direct or indirect material interest.

99.1 to this report and is incorporated herein by reference.
