     CERTIFICATION PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

       I, Paul M Zlotoff, certify that:

         1.   I have reviewed this quarterly report on Form 10-Q of Uniprop
              Manufactured Housing Income Fund;

         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 the 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 registrant as of, and for, the
              periods presented in this quarterly report;

         4.   The registrant's other certifying officers and I are responsible
              for establishing and maintaining disclosure controls and
              procedures (as defined in Exchange Act Rules 13a-14 and 15d-14)
              for the registrant and we have:

                a)  designed such disclosure controls and procedures to ensure
                    that material information relating to the registrant,
                    including its 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)  evaluated the effectiveness of the registrant's disclosure
                    controls and procedures as of a date within 90 days prior to
                    the filing date of this quarterly report (the "Evaluation
                    Date"); and
                c)  presented in this quarterly report our conclusions about the
                    effectiveness of the of the disclosure controls and
                    procedures based on our evaluation as of the Evaluation
                    Date;

         5.   The registrant's other certifying officers and I have disclosed,
              based on our most recent evaluation, to the registrant's auditors
              and the audit committee of registrant's board of directors (or
              persons performing the equivalent function):

                a)  all significant deficiencies in the design or operation of
                    internal controls which could adversely affect the
                    registrant's ability to record, process, summarize and
                    report financial data and have identified for the
                    registrant's auditors any material weaknesses in internal
                    controls; and
                b)  any fraud, whether or not material, that involves management
                    or other employees who have a significant role in the
                    registrant's internal controls; and

         6.   The Registrant's other certifying officers and I have indicated in
              this quarterly report whether or not there were significant
              changes in internal controls or in other factors that could
              significantly affect internal controls subsequent to the date of
              our most recent evaluation, including any corrective actions with
              regard to significant deficiencies and material weaknesses.
