When it comes to commercial real estate, data is your most powerful asset—or your biggest risk. If your comps are outdated, estimated, or incomplete, every decision that follows is on shaky ground.
That’s why leading brokers, analysts, appraisers, and investment professionals trust CompStak, the only CRE data platform built on verified submissions, granular insights, and complete transparency.
Here’s why CRE professionals across the country are making the switch to CompStak.
No Estimates. Just Facts.
Other platforms estimate. CompStak verifies.
Every lease or sale comp in CompStak is sourced directly from real market participants—brokers, appraisers, and researchers—and then fact-checked by humans. Whether you’re reviewing free rent, tenant improvements, cap rates, or net effective rent, you can trust it’s real.
With CompStak, you get:
- Verified, fact-checked data, not AI guesses
- Accurate insights into TI, concessions, NOI, and cap rates
- Confidence in every underwriting, pricing, or investment decision
Verified data > Estimated data

Skip the platform-hopping.
CompStak combines everything you need into one view: lease comps, sale comps, loan data, and property insights. That means less time searching and more time analyzing.
Included on the platform:
- Lease comps with tenant names, expirations, and rent steps

- Loan data with terms, origination dates, and LTV ratios
- Market trends and submarket insights in real time
More data. Fewer gaps.
Concession Data You Won’t Find Anywhere Else
The devil’s in the details and the details are what other platforms leave out.
CompStak surfaces the data that truly drives value, like:
- Free rent periods
- Tenant improvement (TI) allowances
- Net effective rent

If you want to understand the real economics of a deal, this is the data that matters.
Want the real deal? We’ve got it.
Granular, Deal-Level Comps
Market stats are only useful if they’re built on solid, specific data.
CompStak delivers unmatched comp granularity, including:
- Actual tenant names
- Lease expiration dates
- NOI, LTV, and rent trends
- Detailed lease terms and rent escalations
These aren’t just data points, they’re strategic building blocks.
The details make the difference in the deals you make.
Trusted CRE Data From the Market, Not a Model
CompStak doesn’t rely on bots, web scraping, or AI predictions. Instead, our comps come directly from the people doing the deals—then they’re manually verified for quality and accuracy.
You’ll always know:
- Where the data came from
- How it was validated
- That it can be trusted
Real intel from real professionals.
The Non-Disclosure State Advantage
In non-disclosure states like Texas and Utah, most platforms hit a wall. Public record data is limited or non-existent, but CompStak’s crowdsourced model fills in the gaps.
We source verified lease and sale comps from CRE professionals on the ground, so you can access insights where others can’t.
When others stop at “no data,” we dig deeper.
Portfolio-Level Intelligence
CRE strategy shouldn’t live in spreadsheets.
CompStak Portfolios helps you move from manual tracking to proactive decision-making. Instantly view performance metrics across your assets and benchmark against competitors—without building complex models.
With CompStak Portfolios, you can:
- View average rents, TI, free rent, and lease terms
- Identify outperformers and underperformers
- Spot risk and opportunity with benchmarking tools
- Compare portfolios across landlords, submarkets, and REITs
See the big picture, down to the building.
Performance Matrix: Turn Data Into Action
Every building tells a different story. With our Portfolio Performance Matrix, you can read between the lines.
Use it to:
- Flag underperforming buildings with expiring leases → Evaluate for acquisition
- Identify high-performers at rollover risk → Build a hold/sell strategy
- Compare REIT performance and uncover anomalies → Without manual modeling
Strategy needs context. The matrix gives you both.
A Smarter Data Model: Give Comps, Get Comps

Better data in. Better decisions out.
