## Sales Evidence

### Recent closed sales

5 apartments at 9 Prospect Park have recorded sales since September 2021, the most recent for $3,400,000 in June 2025. Prices are the figures recorded with the City, not asking prices.

| Unit | Beds | Sold Price | Sold | Source |
| --- | --- | --- | --- | --- |
| 5C (Apartment) | 3 | $3,400,000 | June 12, 2025 | City record · MLS |
| 14A (Apartment) | 4 | $3,600,000 | March 5, 2024 | City record · MLS |
| 10A (Apartment) | 2 | $2,075,000 | July 7, 2022 | City record · MLS |
| 10-C (Apartment) | 4 | $3,945,000 | May 27, 2022 | City record · MLS |
| 11C (Apartment) | 4 | $3,650,000 | September 21, 2021 | City record · MLS |

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

The median closed price for comparable co-op studio sales in Park Slope is $390,000, based on 13 sales between April 2025 and June 2026. This home is asking $725,000, $335,000 above that median. The middle half of those sales closed between $331,500 and $453,000.

- **Median closed price**: $390,000
- **Middle half**: $331,500 – $453,000
- **Based on**: 13 co-op studio sales in Park Slope
- **Period**: April 2025 – June 2026

Square footage is recorded for only 7 of these 13 sales (54%), 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 8 of these sales with a published asking price, the median closed at 98.9% of what it originally asked. 50% 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 Park Slope instead.

### How these sales were negotiated

- **Sold vs original ask**: 98.9% of the original ask
- **Closed below ask**: 50% of 8 sales
- **Listed → in contract**: 59 days (about 8 weeks)
- **In contract → closed**: 83 days (about 12 weeks)

Across the 8 of these sales with a published asking price, the median closed at 98.9% of what it originally asked. 50% of them closed below the original ask.

Half of these homes were in contract within 59 days (about 8 weeks) of coming to market, based on the 9 with a recorded listing date.

Once a deal was agreed, closing took a further 83 days (about 12 weeks), based on the 9 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 13 co-op studio sales in Park Slope, April 2025 – June 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.
