    NYC rent-stabilized building loans: 3,269 reach their five-year mark this year, into a rate hike and a rent freeze — and who still lends on them

    New York's recorded mortgages, joined for the first time to the rent-stabilized unit count on each building's Department of Finance tax bill and to the city's building class for co-ops. 24,875 active loans, $226B, sit on buildings with registered stabilized units; the largest cohort was written in 2021–22 at the bottom of the rate cycle, and 3,269 of those loans reach their five-year mark between now and October 2027 — into a Fed hike, a 5-year Treasury above 5% and a two-year rent freeze. Who lent in 2019 and who lends now, what happened to Investors Bank's co-op book, and how to read regulation off public records when no city roll records it.

    NYC's 2026 maturity wall, lender by lender: the bank with the most loans coming due is the one pulling back from New York

    A data brief on the lenders behind New York City's 2026 maturity wall: 139 commercial mortgages of $5 million or more, $8.70B, whose maturity date is written into the recorded instrument and falls in the next twelve months, ranked by the institution that originated them and bucketed by lender type. One loan, the GM Building's, is a quarter of the dollars; by count the leader is Flagstar Bank, the former New York Community Bank — while it shrinks its New York book, the Fed raises rates and the city freezes stabilized rents.

    Reonomy alternatives for CRE loan data: why the loans go missing, stale or wrong (2026)

    Brokers, lenders and investors who compared Circlemark with Reonomy, Crexi Intelligence and Capitalize.io kept describing the same four failures: loans that aren't there, loans paid off years ago still listed, maturity dates that were never in the record, and contacts for the wrong person. Each one has a mechanical cause inside the county record. Here is what it is, how to test any vendor for it, and how we handle it — including what we found wrong in our own list, and when.

    Where commercial mortgage maturity data actually comes from

    Every CRE maturity date in every data product traces to one of three sources: the county recorder, securitization disclosure, or somebody's model. What each one covers, what each one hides, and the questions to ask any vendor before you trust a date — with New York and Texas as the worked examples.

    35% of the mortgages that clear a commercial dollar floor in New York City are condo units, co-ops and one-to-four family houses. Here is why the standard property-centric filter can't see them, the one ACRIS field that can, and what our own data looked like before and after we applied it.
