Uniform Loan Delivery Dataset

ULDD Phase 3 Update and Reminder

On November 20, 2018, Freddie Mac and Fannie Mae (the GSEs) provided an update to Phase 3 of the Uniform Loan Delivery Dataset (ULDD), as a follow up to the July 10, 2018, announcement. The GSEs made clarifications to existing ULDD Phase 3 data points, and provided an updated implementation timeline to identify each of their remaining ULDD Phase 3 system implementation dates.

As a reminder, the Phase 3 import file contains all the Phase 2 data in addition to the Phase 3 data, so you can use the Phase 3 import file during the transition period to deliver both Phase 2 and Phase 3 loans.

The ULDD Phase 3 requirements are effective for loans with Application Received Dates on or after January 1, 2019, and delivered on or after May 20, 2019.

The Uniform Loan Delivery Dataset (ULDD) supports the work to implement uniform data standards and defines the data that we require at loan delivery based on loan type, loan feature or other business requirements.

ULDD data is granular, standardized, and has clear definitions, providing sellers with a common understanding of the meaning of each data point. The result is greater transparency, which helps sellers gain a better understanding of our assessment of mortgage risk and purchase requirements on loans they sell to us.
