Change in the building’s median $/sf over each window, on a floor-adjusted basis — standardized to the building’s average floor, so it reflects price rather than which floors happened to sell. This is a different method from The Roebling Index, which publishes plain medians and applies no floor adjustment; the two are not interchangeable. Floor adjustment standardizes for floor only. It does not control for condition, size, exposure, renovation or the mix of what happened to trade. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.

The complete recorded-sale history for Florence Court Condominium, compiled from NYC Department of Finance transfer records, with apartment-by-apartment detail from The Roebling Research Library. Across sales with a public asking price, the building carries a median listing discount of 0.6% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy here.

Each dot is one recorded sale with a known interior square footage, plotted by closing date against price per square foot. The line is the median $/sf each year, adjusted to a floor-standardized (average-floor) unit — so it reflects price movement, not which floors happened to sell that year. Individual sale prices in the table below are unadjusted — and you can click any dot to jump straight to that sale.

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 most recent eligible transfer recorded at this building is from 2024. Our records run through August 2026; no later qualifying sale has been recorded here, which for a small or tightly held building is common rather than a gap in the data.

Sources, exclusions and how these figures are computed

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02644-7501). 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.
