CompStak

CompStak One platform for reliable and accurate commercial real data. We believe that transparency in real estate information results in more effective deal making.

CompStak® is the world's first comprehensive database of commercial deal information (comps). Brokers exchange the comps they have at hand, for the specific comps they need. Residential real estate websites gather home sales comps from public records. In commercial real estate most deals are leases, and there has been no public record for lease comps . . . until now. In addition to lease comps, we now offer commercial sales comps, which allows for complete property insight.

Prime Class A office rents just cleared triple digits. Take away two markets and the story changes.

Across gateway markets, Prime Class A starting rents reached $110.41 per square foot in Q2 2026, up 75.0% from Q4 2019. Excluding New York City and San Francisco, the same measure is $68.04, up 32.3%, and now sits below its Q4 2024 peak.

The gap between those two figures has widened from $8.74 in early 2019 to $42.37. Outside NYC and SF, Prime sits just $7.59 above the rest of Class A.

Below Prime, the market is converging. The rest of Class A reached $60.45 and Class B/C reached $55.48, narrowing the spread between them from $12.02 a year earlier to $4.96.

The hard part of a tax appeal is assembling the comps to back up the argument. Here's how Agent Connect can help. 👇

Ask it to build the appeal case for a property and it resolves the address, assembles the comparable set, itemizes the concessions on each lease, and computes the gap between the assessor's rent assumption and what the space actually costs net of concessions.

Then it shows its work. Every comp carries a verification trail: submitted by a broker, reviewed by an analyst, cross-checked against multiple sources.

Is the office market recovering? It depends on which slice you're looking at.

In Class A, the answer is increasingly yes. Seven of ten gateway markets now rate as recovering, up from four a year ago. In Class B/C, it's moving the other way, with five markets in decline against three.

Demand is just as uneven. AI companies now account for 51.1% of all TAMI leasing, up from 20.2% in 2025, filling the gap left by the rest of the sector.

And landlords are giving away less. New lease concessions are back to their 2019 average of 16.5%, after peaking at 19.9% in 2023.

The rollover question is never one question.

Which leases expire in the next eighteen months, what each one pays now, what the market would pay for that space today, which one you deal with first.

Rent Predictor covers the market side, estimating what each space would rent for today from that building's own leases rather than a submarket average.

With Agent Connect, you ask for the whole table inside ChatGPT, Claude, Gemini, or Copilot, with your rent roll in the same session.

Rents are up across office, retail and industrial. They're just not moving together.

GlobeSt covered our September update to the Columbia CompStak Rent Index (CCRI). Office net effective rents rose 8.8% over the 12 months through July. Retail has softened in recent months, and industrial is settling into a slower, steadier pace.
