This is a composite set of RealtyTrac data on property sales that occurred in the United States between the years 2005 and 2016. The main dataset is composed of RealtyTrac's Tax Assessor Database and includes information on property characteristics, location, ownership, and use. The Data Dictionary and Data Coverage Guide provide detailed information on variables available and geographic coverage.

The data is split into four subsets. Individual properties may be listed in multiple files. The subsets are:

• NYUForeclosure: This file contains information on property in the United States that has had at least one foreclosure transaction between 2005 and 2016. Properties that had no recorded foreclosures during that time period do not appear in the file.
• NYURecorder: This file contains information on property in the United States that has had at least one foreclose transaction and one ownership-changing transaction between 2005 and 2016.
• NYULoans: This file contains information on properties that have had at least one foreclosure transaction and one loan change, such as refinances, equity lines, or equity loans, between 2005 and 2016.
• NYUTaxAssessor: This is the master file of all real estate transactions that have taken place between 2005 and 2016.
