Finance takes into consideration the sales of similar recently sold properties when valuing New York City properties for tax purposes. As such, to make this process more transparent, the agency makes available a detailed listing of all property sales completed in the five boroughs within the past year, as well as historical data dating back to 2003. This information is a matter of public record.

The files linked to below are indexed by borough and neighborhood to facilitate easy lookups of properties, and are provided in two formats: PDF (smaller, more universally accessible files that require the Adobe Reader) and XLS (Microsoft Excel Spreadsheets for power users interested in creating their own sorts and reports). These listings include all properties sold in the last calendar year including cooperative apartments.
