Change in the building’s median $/sf over each window, from the raw yearly medians — too few standardized single-line units here to adjust to an average-floor basis, so which apartments happened to trade moves these alongside price. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.
The complete recorded-sale history for 531 Classon Avenue, compiled from NYC Department of Finance transfer records, with apartment-by-apartment detail from The Roebling Research Library.

Every recorded sale
Sort any column; filter by unit or keyword. Prices are the recorded transfer amount at the NYC Department of Finance. Every sale sits in one of three states: counted in the building’s medians and trend; shown but excluded as a non-arms-length or nominal transfer; or shown and ⚑ flagged for review — a possible duplicate filing or an extreme $/sf outlier, held out of the statistics pending manual verification rather than allowed to move them.

The latest qualifying transfer in our compiled records for this building is from 2024. The dataset is current through September 2026; that does not by itself establish that no later sale occurred.
Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01994-7501; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans. Storage, parking, and commercial units are excluded from all figures. Floor- and line-level $/sf are time-controlled (each sale measured against the building’s going rate at the time of sale) and expressed at today’s pricing, so they isolate the floor or line premium rather than blend two decades of market movement.
Put this data to work.
Know what’s fair before you offer — we’ll show you where each line trades, the building’s discount-to-ask pattern, and where the value sits right now.
Price to the building’s real trajectory, not a guess — we’ll position your line against its true comps to maximize the outcome.
