Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable co-op five-bedroom sales in Upper East Side is $5,300,000, based on 11 sales between January 2025 and May 2026. This home is asking $4,750,000, $550,000 below that median. The middle half of those sales closed between $4,150,000 and $6,425,000. - **Median closed price**: $5,300,000 - **Middle half**: $4,150,000 – $6,425,000 - **Based on**: 11 co-op five-bedroom sales in Upper East Side - **Period**: January 2025 – May 2026 Square footage is recorded for only 3 of these 11 sales (27%), 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. Across the 10 of these sales with a published asking price, the median closed at 92% of what it originally asked. 60% of them closed below the original ask. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Upper East Side instead. ### How these sales were negotiated - **Sold vs original ask**: 92% of the original ask - **Closed below ask**: 60% of 10 sales - **Listed → in contract**: 108 days (about 15 weeks) - **In contract → closed**: 105 days (about 15 weeks) Across the 10 of these sales with a published asking price, the median closed at 92% of what it originally asked. 60% of them closed below the original ask. Half of these homes were in contract within 108 days (about 15 weeks) of coming to market, based on the 10 with a recorded listing date. Once a deal was agreed, closing took a further 105 days (about 15 weeks), based on the 10 with both dates recorded. A co-op board package and its interview account for much of that. 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. Based on 11 co-op five-bedroom sales in Upper East Side, January 2025 – May 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. 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.
