305 East 24th Street (New York Towers)

The building rises 20 floors, the top two given to penthouse units, over a base with roughly 10,000 square feet of Second Avenue retail and a 21,900-square-foot garage per city records. The mix runs from studios through two-bedrooms, with larger combinations assembled over the years — typical post-war proportions: defined foyers, generous closets, windowed kitchens in many lines. Balconied lines and the upper floors carry the premiums; east-facing units get open light toward the East River corridor, and the penthouse levels trade as the building's signature inventory. Renovation quality varies widely unit to unit, which keeps the entry price honest and the renovation arbitrage real.

Full-service at genuine scale: 24-hour doorman and concierge, porter staff, live-in resident manager, and — unusually — an on-site management office, which shareholders credit for responsive day-to-day operations. The garage connects directly to the building and offers a discounted shareholder rate per brokerage records. Storage and bike room run on waitlists. The board's policy framework is among the more flexible in the neighborhood: 75 percent financing, pieds-à-terre, co-purchasing, gifting, guarantors, and washer/dryer installations with approval. The offering plan and amendments are on file in The Roebling Research Library; current financials should be requested through the managing agent during diligence.

Market read. Most recent trades (2026 to date) cleared a median $837/sf (floor-adjusted) across 5 sales. 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 2.7% 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 1-00930-0001). 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 policy stack is the headline. 75 percent financing, pied-à-terre permission, co-purchasing, gifting, and guarantors — this is one of the more accommodating board frameworks in the area, and it materially widens who can buy here relative to stricter Gramercy co-ops. Run the Co-op Board Qualification Calculator before offering, but expect a rational process.

Underwrite the ground-floor economics. The 1983 offering plan disclosed garage and commercial master leases to owner-related entities as a special risk. Your attorney should establish the current status of those leases, the retail income, and the reserve position — we provide the plan and amendments from the Research Library to clients' counsel.

Balconies and line selection drive value. The asymmetrical massing means light and outdoor space vary sharply by line. Walk the specific exposure at different times of day; the spread between the best and weakest lines is wider here than in a conventional slab.

The location is a triangulation play. Gramercy Park, Madison Square Park, the Flatiron restaurant grid, and Union Square's Greenmarket are all a short walk; the 6 train at 23rd and Park is about 0.4 miles. The First Avenue medical corridor — NYU Langone, Bellevue, the VA — makes the building perennially attractive to medical staff and faculty, which supports resale demand.

Verify the fee stack. Sublet fees, any flip tax or transfer fee, and current waitlist timing for storage, bike room, and parking should all be confirmed with the managing agent before contract.

Market the service package against the maintenance. Buyers comparing boutique walk-ups and part-time-doorman stock often underestimate what full staff, an on-site office, and a direct-access garage are worth. State it plainly and price the carry with the True Monthly Carrying Cost Calculator.

Same-building comps are your anchor. For this roughly 388-unit building, check the availability and comparability of recent same-line sales. Adjust neighborhood comparisons for apartment and building differences.

Condition honesty wins. The renovated-versus-estate spread is wide and visible to every buyer touring multiple units in the building. Renovated units clear at premiums; original-condition units clear when priced to the renovation math — run the Renovation Cost Calculator against your asking strategy.
