505 East 79th Street, New York, NY 10075

187 recorded transfers, 2003–2026. 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, adjusted to a floor-adjusted basis — standardized to the building’s average floor, so it reflects price rather than which floors happened to sell. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.

East River House has one of the deeper resale records in its immediate area — ACRIS records more than two hundred share transfers against the lot, running steadily from the years after the 1971 conversion through the current year. That depth is the building's practical advantage in diligence: there is real same-building evidence to price against, which is not true of every co-op on these blocks.

Pricing within the building turns on three variables in roughly this order: outdoor space and exposure, renovation condition, and line size. Balconied and terraced lines with river outlook carry the premium; interior and north-facing lines are the entry tier. Against the surrounding market, the building trades as the large-scale post-war value option in a corridor whose pre-war and East End Avenue stock prices well above it — and, because there is no abatement in the picture, the maintenance figure a buyer sees is the maintenance figure they will keep paying, adjusted only for the building's own budget. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

The complete recorded-sale history for East River House, 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 2.8% 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 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 1-01576-0005) 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.
