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.
The Glen Cairn prices as prewar Riverside Drive condominium inventory, a genuinely small category — most of the Drive is cooperative. That scarcity is the building's clearest pricing advantage, and it is why the building supports pricing above the cooperative comparables on either side of it despite carrying no abatement.
Per-square-foot is the right unit of analysis, run against exposure first. Park-facing residences on the Riverside Drive line and side-street residences on West 99th are different products, and the spread between them is wide enough that a building average will mislead. Floor level matters second, condition third — and condition varies more here than in most buildings, because the conversion renovated vacant apartments and left occupied ones alone. A sponsor-renovated apartment and an original tenant apartment can sit on the same line.
Sales activity has two distinct populations: sponsor closings from 2016 onward, reflecting a slow, deliberate sellout of a building the sponsor was content to rent in the meantime, and secondary resales accumulating since. Comparables should be selected from the same population and indexed to the last complete year. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.
The complete recorded-sale history for The Glen Cairn, 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 0.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy here.

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 1-01888-7504) 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.
