Collateral underwritten without lease data.
Half the income story sits in leases the loan file never shows.
For CMBS Investors · CompStak One Connect
Track rollover and rent exposure across the pool.
Servicer reports show occupancy, not whether in-place rents survive rollover. CompStak gives you lease-level detail on the collateral behind every loan, including where rents sit above today’s market.

What CMBS investors miss without verified comps.
Monitoring is manual and lagged.
Exposure gets recalculated once a quarter, at best.
Sales and loan data alone miss the income story.
Price and LTV say nothing about whether the rent holds.
CompStak One Connect answers each of these with verified, analyst-reviewed comps.
Get StartedLease-level detail behind every loan in the pool.
Underwrite properties in your CMBS portfolio accurately.
Analyze starting rent and lease term trends nationwide, with cap rate, NOI, LTV, and loan maturity dates on the debt side.

Questions about CRE data for CMBS investors.
What lease data matters for CMBS collateral?
Net effective rent, concessions, term, and expiration date on each lease in the building, which is what shows whether the income assumption behind the loan still holds.
Can I monitor rent exposure across a pool?
Yes. Compare in-place rent on collateral leases to what comparable space would lease for today, across every property in the pool.
How does CompStak verify its comps?
Every comp is processed by a multi-step data verification system, including machine learning algorithms, statistical anomaly detection, and a team of CRE data analysts. Read more about our data standard.
What does CompStak One Connect add for CMBS investors?
Rent Predictor, which flags where in-place rent has drifted above what the market would pay now, and Agent Connect, which drafts surveillance notes inside Claude, ChatGPT, Gemini, or Copilot.
How much CRE data does CompStak have?
CompStak has collected 4M+ versions of lease and sale comps across 105 US markets, contributed by more than 40,000 verified CRE professionals and reviewed by CompStak’s analyst team.
