The Strathmore (400 East 84th Street)Recorded sales & closing prices

400 East 84th Street, New York, NY 10028

85 recorded transfers, 2026. Sortable and searchable below.

Co-ops are normally measured by price per room, since square footage is not officially recorded for them. This building is shown in price per square foot because most of its sales carry documented footage, which makes the sharper measure the honest one here.

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.

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.

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 floor-standardized (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.

Sources, exclusions and how these figures are computed

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01563-7501). 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 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.
