### How this price compares

The median closed price for comparable co-op three-bedroom sales in Lenox Hill is $2,583,500, based on 162 sales between September 2024 and July 2026. This home is asking $4,995,000, $2,411,500 above that median. The middle half of those sales closed between $1,806,250 and $3,507,500.

- **Median closed price**: $2,583,500
- **Middle half**: $1,806,250 – $3,507,500
- **Based on**: 162 co-op three-bedroom sales in Lenox Hill
- **Period**: September 2024 – July 2026

Square footage is recorded for only 41 of these 162 sales (25%), 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 157 of these sales with a published asking price, the median closed at 94.6% of what it originally asked. 73% 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 Lenox Hill instead.

### How these sales were negotiated

- **Sold vs original ask**: 94.6% of the original ask
- **Closed below ask**: 73% of 157 sales
- **Listed → in contract**: 69 days (about 10 weeks)
- **In contract → closed**: 101 days (about 14 weeks)

Across the 157 of these sales with a published asking price, the median closed at 94.6% of what it originally asked. 73% of them closed below the original ask.

Half of these homes were in contract within 69 days (about 10 weeks) of coming to market, based on the 154 with a recorded listing date.

Once a deal was agreed, closing took a further 101 days (about 14 weeks), based on the 157 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 162 co-op three-bedroom sales in Lenox Hill, September 2024 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median sold price for co-op three-bedroom sales in Lenox Hill, 2016 to 2026. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth.

| Year | Median sold price | Sales |
| --- | --- | --- |
| 2016 | $2,397,500 | 12 |
| 2017 | $2,500,000 | 59 |
| 2018 | $2,572,500 | 54 |
| 2019 | $2,282,119 | 80 |
| 2020 | $2,167,500 | 38 |
| 2021 | $2,202,500 | 96 |
| 2022 | $2,475,000 | 108 |
| 2023 | $2,250,000 | 90 |
| 2024 | $2,460,000 | 72 |
| 2025 | $2,550,000 | 90 |
| 2026 | $2,673,000 | 55 |

This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Lenox Hill instead.

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.

## Property Taxes

This apartment is part of a co-op that is taxed as one lot shared across 77 apartments. The corporation’s 2026 property tax bill was $2,183,381 for the whole building. Shareholders cover it through their monthly maintenance rather than a separate bill for this unit.
