Introductory Note

     This Amendment No. 33 (this “Amendment”) amends the Statement on Schedule 13D (as amended, the “Statement”) previously filed with the Securities and Exchange Commission by AIMCO Properties, L.P. (“AIMCO Properties”), AIMCO-GP, Inc., Apartment Investment and Management Company, AIMCO IPLP, L.P. and AIMCO/IPT, Inc. (collectively, the “Reporting Persons”).

Item 4. Purpose of Transaction

     Item 4 is hereby supplemented by the addition of the following information:

     The Reporting Persons, which are all affiliates of Fox Partners, the general partner (the “General Partner”) of Century Properties Fund XVII, LP, a Delaware limited partnership (the “Partnership”), have reviewed their investment in the Partnership in light of numerous factors, including, without limitation, general market and economic conditions, their ongoing analysis of the Partnership’s business, financial condition, operations and prospects, the relative attractiveness of alternative investment opportunities and other future developments. As part of this review, the General Partner and AIMCO Properties are considering a merger transaction in which AIMCO Properties would acquire 100% ownership of the Series A units of limited partnership interest in the Partnership (the “Series A Units”). The transaction, if consummated, would result in the Series A Units becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended. The Series B units of limited partnership interest in the Partnership would not be affected by the transaction.

     The terms of the above-described transaction are still being considered, and either AIMCO Properties or the General Partner may decide not to pursue the transaction, or to pursue a different transaction. Although the foregoing reflects potential activities presently contemplated by the Reporting Persons with respect to the Partnership, the foregoing is subject to change at any time, and there can be no assurance that the Reporting Persons will take any of the actions referred to above or participate in a group that will take any of the actions referred to above.

Item 5. Interest in Securities of the Issuer

     Item 5 is hereby amended and restated in its entirety as follows:

     (a)-(b) The information in rows (7) through (11) and (13) of each Reporting Person’s cover page is incorporated herein by reference.

Item 7. Material to Be Filed as Exhibits

     The following is filed herewith as an Exhibit to this Statement:

     Exhibit 7.1      Agreement of Joint Filing, dated July 26, 2011.

SIGNATURE

     After reasonable inquiry and to the best of our knowledge and belief, the undersigned certify that the information set forth in this statement is true, complete and correct.
