Those are excluded from the benchmark below. ### How this price compares - **This home**: $3,595,000 - **Median sold price**: $6,003,000 - **Difference**: -$2,408,000 (-40.1%) - **This home, $/ft²**: $1,411 - **Median $/ft²**: $2,314 - **Comparable sales**: 34 - **Sales from**: November 2024 – July 2026 - **Middle half of those sales**: $4,812,500 – $7,354,393 Based on condo four-bedroom sales in Lenox Hill. 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**: 94.7% (32 sales) - **Sold below asking**: 63% (32 sales) - **Typical time to find a buyer**: 96 days (32 sales) - **Typical time to close**: 64 days (28 sales) Based on condo 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 price per square foot, sales at Diamond House | Year | Median $/ft² | Sales | | --- | --- | --- | | 2019 | $1,095/ft² | 3 (thin) | | 2021 | $1,106/ft² | 5 | | 2022 | $1,337/ft² | 4 (thin) | Based on recorded sales at Diamond House. Years marked "thin" rest on fewer than 5 sales, where a single unusual apartment moves the median a long way. Read those points as the small samples they are rather than as the market turning. Sales data through July 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.
