Fannie Mae has published the updated DU Specification v1.8 and resources supporting implementation of the updated redesigned Uniform Residential Loan Application (URLA/Form 1003) published on Oct. 23, 2019.
The form was initially published in August 2016 and updated in December 2017. It was redesigned to improve the borrower experience, enable lenders to more easily and accurately capture relevant loan application information, and support the industry's move to digitize the loan origination process. To get started, review the documents below.
The DU Specification (DU Spec) is the requirements on how to create a new loan application submission file based on the redesigned Form 1003. This DU Spec, based on the MISMO V3.4 Reference Model, along with other supporting information, including an implementation guide and test case suite (with sample XML files, narratives, as well as 1003, and DTDs for comparison), can be found on the Technology Integration Page for DU. The DU Spec contains the conditionality, cardinality, implementation notes, and other business information for implementing the redesigned Form 1003 in DU.
The ULAD is a mapping of the data fields on the redesigned Form 1003 to the MISMO v3.4 Reference Model dataset. This mapping document will help you understand the field names in the redesigned Form 1003 and their corresponding MISMO data point. This mapping document is not intended for creation of your loan application submission file for DU. The DU Specification MISMO V3.4 (DU Spec) on the Technology Integration for DU Page is the document you should use for updating your systems.
We've created some training resources to help you with your implementation of the redesigned Form 1003 and the DU Spec.
