340 East 72nd Street, Upper East Side

The building is a restrained 1930 red-brick masonry house in the prevailing East Side pre-war idiom — solid, understated, built to last. What distinguishes it is the interior stock. Across 33 residences in a 16-story tower, the layouts are classic pre-war: high beamed ceilings, hardwood floors, separate entry foyers, and the gracious living-and-dining proportions of the era. Several apartments include the small bonus rooms that began as staff quarters and now serve as home offices, nurseries, or guest rooms — a flexible feature that pre-war buyers prize.

A number of homes retain wood-burning fireplaces, and some upper-floor apartments offer open outlooks toward the river; verify light and views for the specific unit. With so few apartments in the building, layouts vary meaningfully floor to floor, and larger combinations require apartment-specific comparables. The building offers a smaller prewar setting; compare actual maintenance and assessments with alternatives before assuming a carrying-cost advantage.

340 East 72nd Street operates as a full-service cooperative. A 24-hour door staff and a live-in resident manager anchor the service model, supported by a renovated fitness center, a central laundry, a bicycle room, and common storage — and, distinctively for a building this size, a landscaped private courtyard garden reserved for shareholders' use. Washer/dryers are permitted within apartments. The building is pet-friendly. The cooperative permits financing of up to 50% of the purchase price; that purchase-financing limit does not establish the corporation's debt or reserve position. Separately, a flip tax of 2% applies, payable by the purchaser at closing. Purchases proceed through a board application and interview in the customary cooperative manner.

Market read. Most recent trades (2026 to date) cleared a median $1,565/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 3.2% 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 1-01446-0038). 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.

Plan around the cooperative's financials before anything else. Financing is capped at 50%, so a substantial down payment is required, and the 2% purchaser-paid flip tax belongs in your closing budget. The board reviews a full cooperative package, and the building's conservative posture rewards strong, liquid buyers who intend the apartment as a primary residence. In exchange you get a rare combination: a true white-glove building with a live-in manager and a private garden, intact pre-war layouts, washer/dryers permitted in-unit, and a pet-friendly policy — all in a quieter, more attainable corner of Lenox Hill, steps from the East River promenade, John Jay Park, and the Second Avenue and Lexington Avenue subways.

Present the service and layout. A 33-unit building with a resident manager and a planted private garden offers specific features to document, and the in-unit washer/dryer allowance and pet policy address practical buyer questions. Apartments that preserve their pre-war proportions — the foyer, the separate dining room, the fireplace — can be presented through measured floor plans and current photography. Infrequent trading and fewer larger homes can limit comparable evidence; neither establishes quick demand or a price premium. Use dated sales of similar prewar apartments in the East 70s and account for condition, exposure and carrying costs.
