Change in the building’s median $/sf over each window, adjusted to a constant-quality (average-floor) unit so it reflects price — not which floors happened to sell. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.

The complete recorded-sale history for The Keystone Building, compiled from NYC Department of Finance transfer records and verified listing data, then enriched apartment-by-apartment by The Roebling Team research desk. Across sales with a public asking price, the building carries a median listing discount of 3.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy here.

Each dot is one recorded sale with a known interior square footage, plotted by closing date against price per square foot. The line is the median $/sf each year, adjusted to a constant-quality (average-floor) unit — so it reflects price movement, not which floors happened to sell that year. Individual sale prices in the table below are unadjusted — and you can click any dot to jump straight to that sale.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00136-7502) 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; 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.
