A Private Pricing Opinion — what your apartment at 1131 Third Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
1131 Third Avenue is a large postwar cooperative in the heart of Lenox Hill — a full-service doorman building. Completed in 1961, it is one of the substantial white-brick-era apartment houses that rose along Third Avenue after the elevated railway came down and the avenue redeveloped into a residential corridor, and at roughly 256 apartments across 21 stories it is among the larger cooperatives on the avenue.
The location is its argument. On Third Avenue at 66th Street, residents are in the center of Lenox Hill — a few blocks from Central Park to the west, with the Lexington Avenue subway, the restaurants and shops of the upper 60s, and the full Upper East Side amenity base at the door. It offers full-service doorman living in a postwar building. Compare its recent sales with those of the Park and Fifth Avenue buildings to the west by size, floor and condition rather than assuming a price gap.
At 256 apartments, 1131 Third has a large shareholder base supporting the full-time staffing and elevatored service of a full-service postwar co-op. Compare an apartment's current maintenance and assessments with those of similar buildings rather than assuming a cost advantage from scale.
Architecture and unit composition
The 1961 vintage places 1131 Third in the postwar idiom: an efficient white-and-tan-brick elevator building with ground-floor retail along Third Avenue, designed for practical, light-filled apartment living rather than pre-war ornament. Layouts run to the postwar standard — studios, one-, and two-bedroom apartments with functional plans, ample closets, and large windows — with larger combinations on the upper floors.
With approximately 256 apartments across 21 floors, the building runs at the higher-density format typical of the avenue's white-brick cooperatives, and individual apartments are best evaluated at the unit level on floor, exposure, and renovation history.
Building operations
1131 Third operates as a full-service postwar cooperative. A full-time doorman staffs the attended lobby, with a resident superintendent on site and central laundry and private storage in the building. The board reviews purchases through a formal application and interview. Confirm the financing requirements, any flip tax, and the sublet rules set by the proprietary lease and house rules at offer stage; the specific financial terms are the policy slate we walk clients through.

Maintenance as recorded with each sale. A co-op's maintenance already covers the building's real estate taxes and the building's own mortgage, if it has one; add your own loan payment for the monthly outlay. A summary of recorded sales, not a current bill; charges change.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.

Market read. Most recent trades (2026 to date) cleared a median $790/sf (floor-adjusted) across 4 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 3.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Confirm the co-op's financial policy before offering. Expect board review; confirm any financing limit, flip tax and sublet rules in the proprietary lease, house rules and application instructions.
The location is the lifestyle. A doorman building in the center of Lenox Hill, near the Park, the 6 train, and the full Upper East Side retail and dining base.
What to know if you’re selling

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
