Square footage is recorded for only 2 of these 10 sales (20%), 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**: 96.2% (8 sales)
- **Sold below asking**: 75% (8 sales)
- **Typical time to find a buyer**: 104 days (7 sales)
- **Typical time to close**: 94 days (7 sales)

Based on studio sales at The Cloister 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.
