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. This standardized trend is a separate series from the latest median above, which is the raw recorded sales. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.
109 East 79th Street trades as a condominium, so pricing is read on a price-per-square-foot basis, and it prices at the top of the Carnegie Hill new-development market. Sponsor sales launched in 2020–2021, with the upper-floor and penthouse inventory commanding the marquee numbers. With 31 highly differentiated units, sales are apartment-specific: floor, exposure, ceiling height, and finish drive the variation. We underwrite each unit against the building's own pricing and the Carnegie Hill / Upper East Side trophy new-development set.

The retrade record
Lines that have changed hands more than once in the public record — the building’s appreciation arc, apartment by apartment.
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 1-01508-7503; each condominium apartment is its own tax lot). 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.
Put this data to work.
Know what’s fair before you offer — we’ll show you where each line trades, the building’s discount-to-ask pattern, and where the value sits right now.
Price to the building’s real trajectory, not a guess — we’ll position your line against its true comps to maximize the outcome.
