Dear Limited Partner:

     Enclosed is our tender offer at a price that we think you should consider.

     - We are offering to acquire your units of limited partnership interest in
       Century Properties Growth Fund XXII for $401.29 per unit in cash.

     - This offer is not subject to any minimum number of units.

     - This offer is not being made as part of the settlement of the Nuanes and
       Heller class and derivative litigation.

     - You will not be required to pay any partnership transfer fees in
       connection with any disposition of your units pursuant to this offer.

BY ACCEPTING OUR OFFER

     - You will receive your final K-1 for this partnership and forever be free
       of tax reporting relative to this investment.

     - You will have been able to convert your interest into cash.

     - You will release us from all liability with respect to any and all claims
       through and including the date of execution of the Letter of Transmittal,
       including, but not limited to, those claims relating to the Nuanes and
       Heller class and derivative litigation, whether or not you requested
       exclusion from the settlement or the judgment is reversed on appeal, and
       assign to us your rights in any future claims. Please see the description
       of the litigation and settlement within the enclosed document.

     - You simply complete and sign the enclosed Letter of Transmittal in
       accordance with the instructions and mail or deliver it and any other
       required documents to The Altman Group, Inc., which is acting as
       Information Agent in connection with this offer.

BY REJECTING OUR OFFER

     - You will remain a limited partner in the partnership, and do not need to
       fill out any papers.

     - You will receive annual K-1's with your tax information.

     The partnership's general partner, which is our affiliate, regularly
evaluates the capital needs, competitive position and market conditions for each
of the properties that the partnership owns, and the general partner uses these
factors to determine whether the partnership will want to continue to own them.
The general partner could decide that the best course of action is to sell some
or all of the assets in the partnership in the near future. Eventually, the
partnership will terminate. You may elect to hold your interest until the
termination of the partnership. If you elect to remain in the partnership until
termination, you will continue to participate in the partnership distributions,
if any, and the tax effects of the partnership's results. In any event, this is
our attempt to provide you some liquidity and to relieve you of your tax
reporting burden.

     If you have any questions, please contact the Information Agent, toll free,
at (800) 467-0821.

                                          Very truly yours,

                                          AIMCO PROPERTIES, L.P.
