This home is asking $949,000, $26,000 below that median. The middle half of those sales closed between $850,000 and $1,467,500. - **Median closed price**: $975,000 - **Middle half**: $850,000 – $1,467,500 - **Based on**: 164 condo one-bedroom sales in Financial District - **Period**: September 2024 – July 2026 - **Median $/ft²**: $1,230/ft² Across the 144 of these sales with a published asking price, the median closed at 95.3% of what it originally asked. 90% 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 Financial District instead. ### How these sales were negotiated - **Sold vs original ask**: 95.3% of the original ask - **Closed below ask**: 90% of 144 sales - **Listed → in contract**: 110 days (about 16 weeks) - **In contract → closed**: 56 days (about 8 weeks) Across the 144 of these sales with a published asking price, the median closed at 95.3% of what it originally asked. 90% of them closed below the original ask. Half of these homes were in contract within 110 days (about 16 weeks) of coming to market, based on the 124 with a recorded listing date. Once a deal was agreed, closing took a further 56 days (about 8 weeks), based on the 144 with both dates recorded. 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 164 condo one-bedroom sales in Financial District, September 2024 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. ### Price trend Median sold price for condo and house one-bedroom sales in Financial District, 2016 to 2026. 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 | | --- | --- | --- | | 2016 | $885,000 | 18 | | 2017 | $1,295,000 | 131 | | 2018 | $1,100,000 | 47 | | 2019 | $938,486 | 45 | | 2020 | $999,000 | 37 | | 2021 | $940,000 | 62 | | 2022 | $950,000 | 77 | | 2023 | $996,500 | 92 | | 2024 | $922,500 | 75 | | 2025 | $999,500 | 96 | | 2026 | $954,500 | 40 | 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 Financial District 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. ## Price and Property History for 15 WILLIAM Street, Unit 10B Review the recorded listing activity for 15 WILLIAM Street, Unit 10B, including asking-price changes and prior market dates. | Date | Price | Listing event | | --- | --- | --- | | July 29, 2026 | $949,000 | Returned to the market | | March 25, 2026 | $949,000 | Listed for sale by Douglas Elliman Real Estate | ## Estimated Monthly Payment **$5,942 / month**, assuming a 20% down payment ($189,800), a 6.5% interest rate and a 30-year term.
