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 market here is small. The sponsor sold the residences between December 2018 and February 2022. Resales began in 2022, and there have been only a few since. Two resales are recorded in the last 24 months. Buyers are paying for a landmarked conversion with irregular, tall-windowed plans and an institutional façade, and there are no close substitutes in the neighborhood.
The assessment roll shows no exemption; abatements are applied at the bill level, so check the apartment's tax bill before relying on the carrying cost. Price resales per square foot against Cobble Hill conversion and new-development resales, not against the neighborhood's brownstone co-ops.
Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

The retrade record
Lines that have changed hands more than once in the public record — the building’s appreciation arc, apartment by apartment.
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 3-00295-7502; 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.
