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.
851 Carroll competes with whole brownstones, brownstone co-ops and condops, and the small boutique condominiums between Seventh Avenue and Prospect Park West. It prices per square foot at the renovated, historic-district end of the Park Slope condominium market, with Unit 1 pricing as the house's large unit and the upper units against full-floor brownstone apartments. With only five units and a sellout that finished in 2026, the building has almost no resale history. Sponsor pricing is the only benchmark so far, and the first true resale will set the building's market. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

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 3-01068-7505). 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.
