Uniform Property Dataset
New! Click here to access the current value acceptance + property data service provider list.
To enhance data quality and consistency in property data collection, Fannie Mae and Freddie Mac (the government-sponsored enterprises or GSEs) have worked together to develop the Uniform Property Dataset (UPD). This work responds to industry feedback requesting market standardization and fungibility, and was done as part of the Uniform Mortgage Data Program® (UMDP®). The UPD is separate from the Uniform Appraisal Dataset, although some data elements and enumerations are aligned.
The UPD consists of all required, conditionally required, and optional data elements for GSE property data collection and supports a full interior and exterior property data collection, including images and floor plan of the subject property.
See below for UPD and Property Data API information and resources.
