### How this price compares

The median closed price for comparable one-bedroom sales at 40 CLARKSON Avenue is $640,000, based on 8 sales between March 2022 and July 2025. This home is asking $645,000, $5,000 above that median. The middle half of those sales closed between $605,000 and $684,797.

- **Median closed price**: $640,000
- **Middle half**: $605,000 – $684,797
- **Based on**: 8 one-bedroom sales at 40 CLARKSON Avenue
- **Period**: March 2022 – July 2025
- **Median $/ft²**: $702/ft²

Across the 6 of these sales with a published asking price, the median closed at 100% of what it originally asked. 50% of them closed below the original ask.

### How these sales were negotiated

- **Sold vs original ask**: 100% of the original ask
- **Closed below ask**: 50% of 6 sales
- **Listed → in contract**: 68 days (about 10 weeks)
- **In contract → closed**: 75 days (about 11 weeks)

Across the 6 of these sales with a published asking price, the median closed at 100% of what it originally asked. 50% of them closed below the original ask.

Half of these homes were in contract within 68 days (about 10 weeks) of coming to market, based on the 7 with a recorded listing date.

Once a deal was agreed, closing took a further 75 days (about 11 weeks), based on the 7 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 8 one-bedroom sales at 40 CLARKSON Avenue, March 2022 – July 2025. 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 one-bedroom sales in Flatbush, 2017 to 2024. 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 |
| --- | --- | --- |
| 2017 | $315,000 | 11 |
| 2018 | $390,000 | 11 |
| 2019 | $308,250 | 14 |
| 2020 | $304,635 | 18 |
| 2021 | $300,000 | 17 |
| 2022 | $300,000 | 19 |
| 2023 | $328,000 | 10 |
| 2024 | $420,000 | 11 |

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 Flatbush 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.

This apartment is part of a co-op that is taxed as one lot shared across 78 apartments. The corporation’s 2026 property tax bill was $320,995 for the whole building. Shareholders cover it through their monthly maintenance rather than a separate bill for this unit.
