Short answer: CoStar is the most widely used CRE data platform and is priced by quote. Reonomy (an Altus Group business) focuses on ownership and owner contacts for prospecting. CompStak specializes in lease and sale comps contributed by brokers and appraisers. Crexi Intelligence combines property records and comps with published monthly pricing. IntellCRE puts comps and market data inside underwriting and deal marketing, rather than replacing a research database.
