Showing the 40 most recent of 44 recorded sales in this period.

Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below.

### How this price compares

- **This home**: $2,800,000
- **Median sold price**: $1,812,500
- **Difference**: +$987,500 (+54.5%)
- **Comparable sales**: 7

Based on three-bedroom sales at 870 United Nations Plaza  37/38B.

Square footage is recorded for only 2 of these 7 sales (29%), 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.

### How these sales were negotiated

- **Sale-to-list price**: 93.3% (7 sales)
- **Sold below asking**: 71% (7 sales)
- **Typical time to find a buyer**: 120 days (6 sales)
- **Typical time to close**: 122 days (6 sales)

Based on three-bedroom sales at 870 United Nations Plaza  37/38B 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.

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.
