Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | PH (Apartment) | 5 | 7,200 | $24,200,000 | $3,361/ft² | December 18, 2025 | City record · MLS | | 7 (Apartment) | 5 | 4,200 | $10,750,000 | $2,560/ft² | April 23, 2025 | City record · MLS | | 10 (Apartment) | 5 | 4,184 | $13,500,000 | $3,227/ft² | April 19, 2023 | 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 five-bedroom sales at 823 Park Avenue is $13,500,000, based on 3 sales between April 2023 and December 2025. This home is asking $11,750,000, $1,750,000 below that median. The middle half of those sales closed between $12,125,000 and $18,850,000. - **Median closed price**: $13,500,000 - **Middle half**: $12,125,000 – $18,850,000 - **Based on**: 3 five-bedroom sales at 823 Park Avenue - **Period**: April 2023 – December 2025 - **Median $/ft²**: $3,227/ft² Across the 3 of these sales with a published asking price, the median closed at 89.6% of what it originally asked. 100% of them closed below the original ask. ### How these sales were negotiated - **Sold vs original ask**: 89.6% of the original ask - **Closed below ask**: 100% of 3 sales - **Listed → in contract**: 202 days (about 29 weeks) - **In contract → closed**: 30 days (about 4 weeks) Across the 3 of these sales with a published asking price, the median closed at 89.6% of what it originally asked. 100% of them closed below the original ask. Half of these homes were in contract within 202 days (about 29 weeks) of coming to market, based on the 3 with a recorded listing date. Once a deal was agreed, closing took a further 30 days (about 4 weeks), based on the 3 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 3 five-bedroom sales at 823 Park Avenue, April 2023 – December 2025. 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.

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 1014101304. 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.
