Exhibit 10.18

                            COVENANT NOT TO COMPETE
                            -----------------------

          This Covenant Not to Compete ("Agreement"), dated as of October 14,
1994, is executed and delivered by ROBERT C. BEASLEY, an individual ("Beasley")
to COMPS InfoSystems, Inc., a Delaware corporation (the "Company"), and is made
contemporaneously with the repurchase by the Company of certain shares of the
Company's stock held by Beasley (the "Repurchased Shares").

                                    RECITALS
                                    --------

          A.  The Company is engaged in the business of providing business
information relating to real estate (the "Business").

          B.  Concurrently with the execution and delivery hereof, the Company
is acquiring the Repurchased Shares pursuant to a Repurchase Agreement between
the Company and Beasley dated on even date herewith (the "Repurchase
Agreement").

          C.  Beasley acknowledges and agrees that he has technical expertise
associated with the Business and is well known in the real estate information
industry.  In addition, Beasley has valuable business contacts with clients and
potential clients of the Business and with professionals in the real estate
information industry.  Furthermore, Beasley's reputation and goodwill are an
integral part of the Company's business success throughout the areas where it
conducts the Business.  Since Beasley has the ability to compete with the
Company in the operation of the Business, the Company therefore desires that
Beasley enter into this Agreement.  But for Beasley's entry into this Agreement,
the Company would not have entered into the Repurchase Agreement with Beasley.
Beasley, in exchange for the consideration to be paid under the Repurchase
Agreement and the consideration described herein, is willing to enter into this
Agreement.

                                   AGREEMENT
                                   ---------

          NOW THEREFORE, as a material inducement to the Company to acquire the
Repurchased Shares, and for other good and valuable consideration, the receipt
and adequacy of which is hereby acknowledged, the parties hereby agree as
follows:

          1.  Term and Consideration.  The term of this Agreement shall commence
              ----------------------                                            
on the dated hereof (the "Closing Date") and shall expire on the seventh
anniversary of the Closing Date (the "Term").  As consideration, Beasley shall
be paid $4,336 on a monthly basis beginning with November, 1994 and ending in
May, 1996.

          2.  Covenant Not to Compete.  Unless acting in accordance with the
              -----------------------                                       
Company's prior written consent, Beasley shall not, directly or indirectly, own,
manage, join, operate or control, or participate in the ownership, management,
operation or control of, or be connected as a director, officer, employee,
partner, consultant or otherwise with, or permit his name to be used by or in
connection with, any profit or non-profit business or organization that engages
in the business of providing real estate information in the States of California
or Arizona, it being understood that the foregoing shall not limit Beasley from
(a) making passive

 
investments of less than 5% of the outstanding equity securities in any entity
listed for trading on a national stock exchange or quoted on any recognized
automatic quotation system, or (b) acting as an officer of the Company.

          3.  No Solicitation of Customers or Employees.  Beasley agrees that:
              -----------------------------------------                       

              (a) during the Term, Beasley shall not, directly or indirectly,
call on or solicit or divert or take away from the Company (including without
limitation by divulging to any competitor or potential competitor of the
Company) any person, firm, corporation or other entity who is or which at the
Closing Date was a customer of the Company or whose identity is known to Beasley
at the Closing Date as one whom the Company intends to solicit; and

              (b) during the Term, Beasley shall not, directly or indirectly,
solicit or seek to hire or offer employment to any employee of the Company or
any employee of any successor or affiliate of the Company which is engaged in
the real estate information business, unless the employment of such employee is
terminated or the Company gives written consent to such employment or offer of
employment.

          4.  Severability of Provisions.  In the event that the provisions of
              --------------------------                                      
Section 2 and Section 3 ever be adjudicated by a court of competent jurisdiction
to exceed the time or geographic or other limitations permitted by applicable
law, then such provisions shall be deemed reformed to the maximum time or
geographic or other limitations permitted by applicable law, as determined by
such court in such action.  Without limiting the foregoing,  the covenants
contained herein shall be construed as separate covenants, covering their
respective subject matters, with respect to (a) each of the separate cities,
counties and states of the United States, in which the Company or its successors
now transacts any business, (b) each business now conducted by any of the
Company or its successors, and (c) the Company and its successors separately.

          6.  Injunctive Relief.  Beasley acknowledges that (a) the provisions
              -----------------                                               
of Section 2 and Section 3 are reasonable and necessary to protect the
legitimate interests of the Company, and (b) any violation of Section 2 or
Section 3 will result in irreparable injury to the Company, the exact amount of
which will be difficult to ascertain, and that the remedies at law for any such
violation would not be reasonable or adequate compensation to the Company for
such a violation.  Accordingly, Beasley agrees that if Beasley violates the
provisions of Section 2 or Section 3, in addition to any other remedy which may
be available at law or in equity, the Company shall be entitled to specific
performance and injunctive relief, without posting bond or other security, and
without the necessity of proving actual damages.

          7.  Notices.  All notices, requests, demands and other communications
              -------

including the arbitrators' fees, expert witness fees, and attorneys' fees, may
be awarded to the prevailing party, in the discretion of the arbitrator, or may
be apportioned among the parties in any manner deemed appropriate by the
arbitrator.  Unless and until the arbitrator decides that one party is to pay
for all (or a share) of such expenses, each party to the dispute shall bear its
own fees and costs arising in connection with the enforcement of the Agreement.
Not withstanding the foregoing, the Company, in accordance with the provisions
of Section 5 of this Agreement, may seek equitable enforcement of the terms of
this Agreement in any court of competent jurisdiction.

              -------------                                                 
and the rights of the parties determined in accordance with the laws of the
State of California.

be duly executed on their respective behalf, by their respective officers
thereunto duly authorized, all as of the day and year first above written.
