Those are excluded from the benchmark below. ### How this price compares - **This home**: $4,225,000 - **Median sold price**: $17,100,000 - **Difference**: -$12,875,000 (-75.3%) - **This home, $/ft²**: $1,276 - **Median $/ft²**: $3,493 - **Comparable sales**: 14 - **Sales from**: December 2024 – June 2026 - **Middle half of those sales**: $7,787,500 – $19,853,469 Based on condo five-bedroom sales in Lenox Hill. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Lenox Hill instead. ### How these sales were negotiated - **Sale-to-list price**: 94.2% (13 sales) - **Sold below asking**: 85% (13 sales) - **Typical time to find a buyer**: 123 days (13 sales) - **Typical time to close**: 93 days (13 sales) Based on condo five-bedroom sales in Lenox Hill with the required listing and closing data. Sample sizes vary by metric. 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. Sales data through June 2026. 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 1014521026. 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.
