365 West 20th Street (Chelsea Court Tower)

The building rises 16 stories at the corner, with retail in the limestone base along Ninth Avenue and the residential entrance on the tree-lined side street. Apartments run from studios and one-bedrooms through two-bedroom lines; pre-war proportions hold throughout — defined foyers, dining alcoves, bay windows in select lines — and the top floors carry the building's trophy inventory, including units with wood-burning fireplaces and wrap terraces per listing records. The center lightwell above the avenue and the corner siting give most lines real light; south- and west-facing units take the seminary close and the historic-district roofscape.

This is a moderate-service co-op run lean: doorman coverage from 4 p.m. to midnight, a live-in superintendent, two passenger elevators, central laundry (in-unit washer/dryers are not permitted), a shared landscaped roof deck, and storage and bike allocations at no charge — one per unit, per the management questionnaire on file. There is no garage and no fitness center. The financial record on file shows a 2018 refinancing that meaningfully rebuilt reserves, a fully funded reserve at the sponsor-reporting level, and two commercial units contributing avenue retail income. Sponsor-related parties retained a block of rent-stabilized units at the date of the questionnaire on file; your attorney should confirm the current sold percentage during diligence.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,271/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.5% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00744-0001). 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 on co-ops is not officially recorded, figures shown are approximate.

The block is the asset. West 20th Street between Ninth and Tenth is the seminary block — Cushman Row, the General Theological Seminary close, full tree canopy. Upper floors may look over landmarked Chelsea, but views depend on floor and exposure, and no view is protected without a recorded instrument. Walk the block at dusk before you decide; it is the product.

The financing framework is documented. 80 percent financing per the management questionnaire on file, and the board's documented case-by-case posture on pieds-à-terre, gifting, and co-purchase, are the terms to plan around. Run the Co-op Board Qualification Calculator before offering.

Understand the flip tax before you model returns. The seller-paid fee is tenure-tiered per the questionnaire on file: 2 percent of price in roughly the first two years, then $18 per share and later $15 per share. Because the first tier is a percentage of price and the later tiers are per share, which charge is larger depends on the apartment's price and share allocation — 2 percent of price equals $18 a share only at a price of $900 per share. Compute the applicable tier for the specific apartment and confirm the current schedule.

Service expectations should be calibrated. Part-time door coverage and central laundry define the service level; they do not establish moderate maintenance. Buyers coming from full-service buildings should weigh the staffing model honestly — and washer/dryer hopefuls should know in-unit installation is not permitted.

Verify the sponsor position and sublet terms. The documents on file record sponsor-related rent-stabilized units and a handful of sublets as of their date; current counts and current sublet policy should be confirmed with the managing agent during attorney diligence.

Sell the district without being in it. The marketing story is precise: protected seminary-block views and pre-war architecture at the corner, with none of the LPC alteration friction an in-district owner faces inside the unit. Use the geography with specificity.

Lead with the policy stack. 80 percent financing, pets, and case-by-case flexibility on structures are documented terms. State them plainly in the setup.

Position against West Chelsea's condos on value. The buyer pool for this corridor is anchored by the High Line and gallery district; your per-foot discount to new condo product two avenues west is the argument. Renovated condition clears at a premium — run the Renovation Cost Calculator against your asking strategy if the unit is original.
