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 Strathmore's current sales cycle is a sponsor conversion, so pricing reflects launch pricing on the converting inventory rather than a long secondary-market history. Launch pricing has run broadly from the high-$900,000s for one-bedroom inventory into the low-$2 million range for two-bedrooms and higher for three- and four-bedroom homes, with individual unit pricing set against the specific layout, floor, and exposure. Because the building is priced on a cooperative (per-room) convention, comparable analysis should reference the room count and layout rather than a strict per-square-foot figure.

As with any sponsor conversion, the offering plan governs — pricing, terms, the affordable-rental split, and any sponsor obligations should all be confirmed against it.

The complete recorded-sale history for The Strathmore, compiled from NYC Department of Finance transfer records and verified listing data, then enriched apartment-by-apartment by The Roebling Team research desk.

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.

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.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01563-7501) 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 on co-ops is not officially recorded, figures shown are approximate. 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.
