About
What Circlemark is
Circlemark is a commercial mortgage maturity data platform for commercial real estate brokers. We index every commercial mortgage in the county record, read the maturity date off the recorded instrument where it states one, and keep each loan's status current against the record every week — so a broker can find the loans coming due, the loans past a stated maturity with no payoff recorded, and the loans in distress, before anyone else calls.

Live counts from our database across 5 metros, as of Oct 22, 2026.
What we index
New York City — every commercial mortgage, consolidation (CEMA), satisfaction, assignment, modification and foreclosure recorded in ACRIS across its four boroughs (Manhattan, the Bronx, Brooklyn and Queens) since 2004, joined to the city's PLUTO parcel file.
Dallas–Fort Worth — the county clerk real-property records of Dallas, Tarrant and Collin counties since 2015, joined to the central appraisal districts. The Texas index publishes no loan amount, so we read the principal from page one of each recorded deed of trust.
Houston — every deed of trust recorded with the Harris County Clerk since 2015, whose index is free and whose instruments are read whole, joined to the Harris Central Appraisal District's roll, which cites the clerk's file number on most accounts. The clerk's portal allows a fixed number of document downloads a day, so Houston's instruments are still being read and its counts grow weekly until the backfill completes.
Austin — every deed of trust recorded with the Travis County Clerk since 2015, read the same way and joined to the Travis Central Appraisal District's parcel file, whose roll cites the clerk's instrument number.
San Antonio — every deed of trust recorded with the Bexar County Clerk since 2015, read the same way and joined to the Bexar Appraisal District's parcel file.
We are working through the 50 largest US metros, county by county. A metro appears here only once its index is backfilled and its documents are being read; where that reading is still under way, the metro's page says so.
Every field traces to a citable public record and carries its provenance; modelled estimates are always labelled as estimates. The full sourcing and verification story is on the methodology page. The data is available in the app, by weekly email digest, and inside Claude through our MCP connector.
Who builds it
Circlemark is built by a small engineering team with backgrounds at UC Berkeley, Apple and Lyft. It is a product of Revar.
Andrew Zhong, founder, writes the guides and data briefs on this site and builds the pipelines that read the county record behind them. Every figure in a post is counted from the loans Circlemark tracks, on the date the post gives. Find him on LinkedIn.
