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.
350 West 23rd Street prices on a price-per-square-foot basis against the Chelsea condominium market, and the comparable set should be 2005-to-2012 boutique new construction, not prewar loft conversion. That distinction is the single most consequential thing to get right about this address, and getting it wrong in either direction moves the number.
Inside the building, the A and B lines produce paired comparables on each floor, and the value spread is driven by outdoor space more than by anything else: the two first-floor residences with private rear gardens, the residences with balconies, and the top-floor residences with assigned roof areas each sit in a different band from the plain plates. Floor level and light matter, but on a fifty-foot mid-block lot with light from the street and the rear, outdoor space is the differentiator that reads in a price.
Against the wider Chelsea market this is boutique, unstaffed, entirely residential product with large plates and no remaining tax benefit. Its limited services and large layouts differ from full-service towers and smaller Eighth Avenue apartments. Compare the actual purchase price, floor area, taxes, common charges and assessments before asserting a cost advantage. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.
The complete recorded-sale history for Modern 23, compiled from NYC Department of Finance transfer records, with apartment-by-apartment detail from The Roebling Research Library. Across sales with a public asking price, the building carries a median listing discount of 10.0% 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.

The latest qualifying transfer in our compiled records for this building is from 2023. The dataset is current through September 2026; that does not by itself establish that no later sale occurred.
Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00746-7507; 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.
