249 East 62nd Street (The Treadwell)Recorded sales & closing prices

The Treadwell launched sales during construction with an offering that ran from roughly $1.005 million for the smallest studios to $3.95 million at the top of the original release. That range is the useful frame: this is a new-development condominium priced to reach entry-level and mid-market Upper East Side buyers, not a trophy building competing with the Park and Fifth Avenue tier or with the Billionaires' Row product.

Pricing power at The Treadwell lives in three variables — floor, exposure, and whether the residence carries a balcony. Because the building runs only two to four homes per floor, line-to-line comparison is thin, and the right anchor for any given residence is usually a same-line or adjacent-floor sale rather than a building average. Buyers should also weigh the building against the two adjacent product categories in Lenox Hill: mid-century cooperative inventory, which trades at a substantial per-square-foot discount but carries approval risk, restricted use, and in several nearby buildings a ground lease; and recent condominium conversions of post-war rentals, which offer condominium form at older building systems.

Sellers at a 2024-completion building face the standard resale-versus-sponsor question. Where sponsor inventory remains, resale listings compete with a seller who has different price discipline, a full marketing apparatus, and the ability to offer concessions. Establishing how much sponsor inventory is left, and at what pricing, is the first diligence item in any resale listing conversation here.
