Showing the 40 most recent of 139 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

The median closed price for comparable one-bedroom sales at CLAREMONT HALL is $1,340,000, based on 45 sales between September 2023 and May 2026. This home is asking $1,385,000, $45,000 above that median. The middle half of those sales closed between $1,270,000 and $1,430,641.

- **Median closed price**: $1,340,000
- **Middle half**: $1,270,000 – $1,430,641
- **Based on**: 45 one-bedroom sales at CLAREMONT HALL
- **Period**: September 2023 – May 2026
- **Median $/ft²**: $1,660/ft²

Across the 44 of these sales with a published asking price, the median closed at 94.9% of what it originally asked. 96% of them closed below the original ask.

### How these sales were negotiated

- **Sold vs original ask**: 94.9% of the original ask
- **Closed below ask**: 96% of 44 sales
- **Listed → in contract**: 20 days
- **In contract → closed**: 41 days (about 6 weeks)

Across the 44 of these sales with a published asking price, the median closed at 94.9% of what it originally asked. 96% of them closed below the original ask.

Half of these homes were in contract within 20 days of coming to market, based on the 45 with a recorded listing date.

Once a deal was agreed, closing took a further 41 days (about 6 weeks), based on the 45 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 45 one-bedroom sales at CLAREMONT HALL, September 2023 – May 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median price per square foot for sales at CLAREMONT HALL, 2023 to 2026. Price per square foot is used rather than sale price so the line follows the market rather than whichever apartments happened to change hands that year.

| Year | Median $/ft² | Sales |
| --- | --- | --- |
| 2023 | $1,808/ft² | 23 |
| 2024 | $1,747/ft² | 54 |
| 2025 | $1,765/ft² | 30 |
| 2026 | $1,815/ft² | 12 |

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.

## Property Tax History

Taxes at 100 CLAREMONT Avenue #17C were $15,057 in 2026, up 4.1% from 2025.

| Year | Tax Assessment | Land | Additions | Billable Value | Property Tax | Tax Rate |
| --- | --- | --- | --- | --- | --- | --- |
| 2026 (FY 2026/27) | $120,453 | $1,901 | $118,552 | $120,453 | $15,057 | 12.5% (estimated) |
| 2025 (FY 2025/26) | $115,735 | $1,901 | $113,834 | $115,735 | $14,467 | 12.5% (estimated) |
| 2024 (FY 2024/25) | $147,511 | $1,901 | $145,610 | $147,507 | $18,438 | 12.5% |

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.

Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.

Figures are the New York City Department of Finance assessment roll for tax lot 1019921075. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
