SAN DIEGO, CA, September 1, 1999 -- COMPS.COM (NASDAQ: CDOT) today reported it
has significantly expanded its operations in Texas, one of the largest
commercial real estate markets in the country, by acquiring the assets of the
Flick Report and the COMMERCIAL Broker's Network of Austin, Texas. The Flick
Report is a bi-monthly publication serving the commercial real estate leasing
and sales markets in the Austin and central Texas area. The COMMERCIAL Broker's
Network is an Internet marketing tool for commercial property leases and for
sale properties (http://www.combroker.com). Terms regarding the transaction were
                 ------------------------
not disclosed.

Christopher A. Crane, Chief Executive Officer of COMPS.COM, said "We are excited
about the addition of the Flick Report and the COMMERCIAL Broker's Network. The
Flick Report is a market-leading publication that is recognized in the Central
Texas area as the primary source of commercial real estate information. Combined
with the Baca Information Group acquisition earlier this month, this transaction
establishes COMPS.COM as a major player in the Texas commercial real estate
information industry. Three of the ten largest cities in the US are in Texas, so
it is important that COMPS.COM invest in this rapidly growing and prosperous
area. The COMMERCIAL Broker's Network Internet platform complements COMPS.COM's
Internet delivery platform and gives us a head start in providing our customers
in Texas with Internet information and transaction services."

Elliott Flick of the Flick Report and the COMMERCIAL Broker's Network, commented
"We are pleased to become part of COMPS.COM because we share the same philosophy
about the real estate business - that real estate information is essentially
local to the market and you need to build from the grass roots up. The Internet
offers innumerable opportunities for our industry and at combroker.com we have
made substantial progress toward meeting our customers needs. With COMPS.COM's
resources, we will be able to accelerate that effort, solidify our leadership
position in the Central Texas market, and contribute to COMPS.COM's Internet
activities."

COMPS.COM went public in May 1999, selling 4.5 million shares of common stock
and raising net proceeds of approximately $62.2 million.
