Uniform Property Dataset Drives Property Data Quality

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).

The UPD consists of all required, conditionally required and optional data elements for GSE property data collection and supports a full interior and exterior data collection, with images and floor plan of the subject property.

Introducing the Uniform Property Data Report (UPDR)

The GSEs are pleased to announce the publication of the UPDR. This dynamic, standardized report template is designed to bring greater efficiency and consistency to the underwriting and review processes. The GSEs developed the UPDR in direct response to industry feedback regarding the challenges of working with different property data output formats, which can create unnecessary complexity and delays. The new UPDR’s standardized format addresses those challenges to help streamline review processes, simplify training across the industry and enable automated data validation.
