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.
Since there is no abatement, the carrying cost is what it appears to be. There is no abatement burn-off coming. 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 complete recorded-sale history for The Polhemus; historically the Polhemus Memorial Clinic, or the Polhemus Building, compiled from NYC Department of Finance transfer records and verified listing data, then enriched apartment-by-apartment by The Roebling Team research desk.

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) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price. 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.
