Uniform Property Dataset

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.

Updated Delivery Specification and User Guide

We’ve updated the UPD Delivery Specification and Property Data Collection User Guide to include mapping of the UPD to the Form 1004 and Form 1073 (UAD 2.6) report templates. Access these documents on our Technical Resources tab.
