EXHIBIT 31.2

                     RULE 13a-14(a)/15d-14(a) CERTIFICATION



         I, Michael Rider, certify that:

1.       I have reviewed this Form 10-Q of Primecore Mortgage
         Trust, Inc.;

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
         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, or
         caused such disclosure controls and procedures to be
         designed under our supervision, 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 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

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

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 control over financial
         reporting.
