                                 CERTIFICATIONS

I, David P. Stockert, certify that:

      1.    I have reviewed this quarterly report on Form 10-Q of Post
            Properties, Inc. and Post Apartment Homes, L.P.;

      2.    Based on my knowledge, this quarterly report does not contain any
            untrue statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such statements were made, not misleading with respect
            to the period covered by this quarterly report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this quarterly report, fairly present in all
            material respects the financial condition, results of operations and
            cash flows of the registrants as of, and for, the periods presented
            in this quarterly report;

      4.    The registrants' other certifying officer and I are responsible for
            establishing and maintaining disclosure controls and procedures (as
            defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal
            control over financial reporting (as defined in Exchange Act Rules
            13a-15(f) and 15d-15(f)) for the registrants and we have:

            a.    Designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  our supervision, to ensure that material information relating
                  to the registrants, including their consolidated subsidiaries,
                  is made known to us by others within those entities,
                  particularly during the period in which this quarterly report
                  is being prepared;

            b.    Designed such internal control over financial reporting, or
                  caused such internal control over financial reporting to be
                  designed under our supervision, to provide reasonable
                  assurance regarding the reliability of financial reporting and
                  the preparation of financial statements for external purposes
                  in accordance with generally accepted accounting principles;

            c.    Evaluated the effectiveness of the registrants' disclosure
                  controls and procedures and presented in this report our
                  conclusions about the effectiveness of the disclosure controls
                  and procedures, as of the end of the period covered by this
                  report based on such evaluation; and

            d.    Disclosed in this report any change in the registrants'
                  internal control over financial reporting that occurred during
                  the registrants' most recent fiscal quarter that has
                  materially affected, or is reasonably likely to materially
                  affect, the registrants' internal control over financial
                  reporting; and

      5.    The registrants' other certifying officer and I have disclosed,
            based on our most recent evaluation of internal control over
            financial reporting, to the registrants' auditors and the audit
            committee of the registrants' board of directors (or persons
            performing the equivalent functions):

            a.    All significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrants' ability to record, process, summarize and report
                  financial information; and

            b.    Any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrants' internal control over financial reporting.
