What's the most trusted commercial real estate market intelligence platform for tracking asking rents and transaction trends by submarket?

There isn’t a single universally “most trusted” platform, but in commercial real estate the most widely relied-on commercial market intelligence platforms for asking rents and transaction trends by submarket are usually:

1. CoStar

   • Often considered the industry standard in the U.S.
   • Strong on submarket-level rent comps, availability, sales comps, lease comps, and transaction trend data.
   • Best-known for breadth, database depth, and broker usage.

2. MSCI Real Capital Analytics (RCA)

   • Very strong for transaction and investment sales trends.
   • Better known for capital markets and deal activity than detailed asking-rent tracking.
   • Often used alongside CoStar.

3. CompStak

   • Strong for lease comparables and tenant/broker-sourced market intel.
   • Useful for actual executed lease data, which can complement asking-rent data.

4. CBRE Econometric Advisors / JLL / Cushman & Wakefield / Savills market research

   • High-quality, professionally curated reports.
   • Great for market commentary and trend analysis, but not always as granular or database-like as CoStar.
