### How these sales were negotiated

- **Sale-to-list price**: 100% (9 sales)
- **Sold below asking**: 33% (9 sales)
- **Typical time to find a buyer**: 85 days (9 sales)

Based on condo three-bedroom sales in Greenwood Heights 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 July 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.

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 3008911102. 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.
