46 recorded transfers, 2003–2026. 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.
443 12th Street trades as landmarked loft co-op product in a district of brownstones. It is priced per room like the rest of the Park Slope co-op market, but buyers are paying for ceiling height, window size and open plan. The within-building spread is wide. The basement/first-floor duplexes, the fifth-floor apartments — especially the two with exclusive roof areas — and fully renovated lofts set the top of the range. Apartments that keep the original raised-platform layout are priced as projects, because turning a sleeping loft into an enclosed bedroom is a major renovation that needs board approval.
The co-op structure sets the buyer pool: a board package, an interview, sublets limited to two apartments at a time, and financing subject to board approval. That favors owner-occupants and narrows the investor market. The real comparison set combines Brooklyn's other converted-industrial co-ops, the loft condominiums across the street and the Park Slope prewar co-op market, adjusted for the step down from condominium flexibility. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.
The complete recorded-sale history for Ansonia Storage Warehouse, 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 1.8% 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 3-01096-0050). 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.
