A private elevator landing opens to a gracious twenty-five-foot gallery, leading to a splendid enfilade of entertaining rooms overlooking Park Avenue. Extending approximately 90 feet along the Avenue, these rooms include the grand living room, handsome Library and the corner formal dining room. A Powder room is off the library. There are wood-burning fireplaces with exquisite mantles in the living room and the library. The exceptionally large windows and ten-plus-foot ceilings enhance the sense of sophistication and elegance throughout. The meticulously designed chef's kitchen is expansive and inviting, with six windows, a large center island, custom cabinetry, and an eat-in area perfectly situated below a wall of windows. Well-suited for a serious chef and larger-scale entertaining, the kitchen is equipped with two Viking ovens, a Miele cooktop, two Miele dishwashers, two warming drawers, two sinks, and a Sub-Zero refrigerator. A separate butler's pantry provides extra storage. A hallway off the kitchen is lined with extra closets and leads to the large staff room and laundry room. The private quarters are set off a wide hallway. Originally two bedrooms, the huge corner primary suite faces Park Avenue and south with beautiful views down the avenue. There is a large dressing area and walk-in closets. The marble-clad primary bathroom is very large and sunny. Two additional bedrooms are generously proportioned, each with an ensuite bathroom and ample closet space. A separate staff room on the ground floor and two private storage rooms transfer with the apartment. There is through-wall air conditioning throughout. Completed in 1926, 660 Park Avenue is a sought-after cooperative comprising twelve full-floor residences. The building offers impeccable service including doormen, porters and a resident manager. Financing is not permitted. There is a 2% flip tax payable by the buyer. ## Property Details - **Property Type**: Co-op - **Beds**: 4 - **Total Baths**: 5 - **Rooms**: 9 - **Sqft**: 4,700 sqft - **Stories**: 14 - **Year Built**: 1926 - **Price per Sqft**: $2,979 - **Common Charges**: $14,232 / Monthly - **Listed On**: Sep 10, 2026 - **Days on Market**: 22 Days ### Residence Features - Building Other - City ## Estimated Monthly Payment **$85,024 / month**, assuming a 20% down payment ($2,800,000), a 6.5% interest rate and a 30-year term.

Square footage is recorded for only 14 of these 41 sales (34%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Lenox Hill instead. ### How these sales were negotiated - **Sale-to-list price**: 99.2% (38 sales) - **Sold below asking**: 53% (38 sales) - **Typical time to find a buyer**: 71 days (41 sales) - **Typical time to close**: 96 days (41 sales) Based on co-op four-bedroom sales in Lenox Hill with the required listing and closing data. Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. ### Price trend Median sale price, co-op four-bedroom sales in Lenox Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $5,875,000 | 15 | | 2018 | $4,595,000 | 18 | | 2019 | $2,600,000 | 11 | | 2020 | $3,550,000 | 11 | | 2021 | $3,800,000 | 24 | | 2022 | $3,062,500 | 24 | | 2023 | $4,100,000 | 24 | | 2024 | $4,825,000 | 36 | | 2025 | $4,150,000 | 19 | | 2026 YTD | $4,525,000 | 16 | Based on recorded co-op four-bedroom sales in Lenox Hill. 2026 is year-to-date. Sales data through August 2026. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
