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.
Resales are infrequent — roughly one a year across 20 apartments since the sellout, with some years showing none — which is normal for a small, fully owner-held condominium. The building trades against South Williamsburg's mid-2000s condominium stock, not against the new construction of the 2020s. Within that set, the variables are size, floor and condition. Most buildings of that cohort have come off their 421-a benefits or are near the end, so the tax comparison is closer to even than it is against newer abated stock. 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 3-02264-7515). 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.
