73 recorded transfers, 2004–2026. Sortable and searchable below.
Co-ops are normally measured by price per room, since square footage is not officially recorded for them. This building is shown in price per square foot because most of its sales carry documented footage, which makes the sharper measure the honest one here.

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 building trades. NYC Department of Finance recorded transfers show a continuous history at this tax lot from May 2004 through November 2025, which is what distinguishes a working HDFC cooperative from a purely regulated rental. The recorded-price record is maintained in The Roebling Research Library and reproduced in the data room on this page.
Pricing at an HDFC is not directly comparable to open-market Harlem co-op pricing, because the income restriction and any resale formula constrain the buyer pool and, in some buildings, the price itself. Read the recorded figures against the corporation's own resale terms rather than against the surrounding market.
The complete recorded-sale history for Madison Park Apartments, 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 3.6% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy here.

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.

Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01746-0021). 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 on co-ops is not officially recorded, figures shown are approximate. 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.
