Dear Ms. Adams:

         We have received the comment letter, dated March 3, 2005, issued by the
staff of the Securities and Exchange Commission (the "Commission") with respect
to the Schedules TO and Schedules 13E-3 referenced above. AIMCO Properties,
L.P., AIMCO-GP, Inc., Apartment Investment and Management Company, and the other
filing persons of the partnerships as shown in Schedule I hereto (collectively,
the "Filing Persons") acknowledge the following:




o        The Filing Persons are responsible for the adequacy and accuracy of the
         disclosure in their filings;

o        Staff comments or changes to disclosure in response to staff comments
         in the filings reviewed by the staff do not foreclose the Commission
         from taking any action with respect to the filing; and

o        The Filing Persons may not assert staff comments as a defense in any
         proceeding initiated by the Commission or any person under the federal
         securities laws of the United States.


                                    Very truly yours,
