Redesigned to improve the borrower and lender experience

Fannie Mae and Freddie Mac (the GSEs) redesigned the Uniform Residential Loan Application (URLA) (Fannie Mae Form 1003) and created new automated underwriting system (AUS) specifications (Fannie Mae Desktop Underwriter® [DU®] Spec) to help lenders better capture relevant loan application information and support the industry’s move to digitize the loan origination process.

The GSEs also created a Uniform Loan Application Dataset (ULAD) to show how Form 1003 is mapped to MISMO® v3.4 Reference Model and a voluntary Supplemental Consumer Information Form (SCIF/Form 1103) to assist lenders in capturing information on borrower homeownership education, housing counseling and language preference information.

Redesigned Form 1003 now required

Effective May 1, 2021, any new loan applications using the legacy Form 1003/DU file format will receive an Out of Scope or Error recommendation and will not be underwritten by DU. If you have new loans in legacy formats that have not had a casefile ID assigned by DU by April 30, you must recreate the application using the redesigned Form 1003 and DU MISMO v3.4 file format. This may require obtaining additional information from your borrower to ensure that you have all data required by the redesigned Form 1003.

Implementation Timeline for the Updated Automated Underwriting System (AUS) Specifications

Following the March 1 mandate, which required the use of the redesigned Uniform Residential Loan Application (URLA/Form 1003) and Desktop Underwriter® (DU®) MISMO v3.4 file formats for all new loan applications, software providers should now update their systems in accordance with established GSE release schedules and implementation agreements.

Guidance

 

The legacy Form 1003 may no longer be used for new loan applications. Effective May 1, 2021, any new loan applications using the legacy Form 1003/DU file format will receive an Out of Scope or Error recommendation and will not be underwritten by DU. Any existing loans in the legacy 1003 3.2 or MISMO V. 2.3.1 formats may remain in legacy format.

See the Mandate and Implementation Timeline section of the Redesigned Form 1003/DU Quick Guide for more information on legacy re-/submission deadlines.

The DU Spec, based on the MISMO v3.4 Reference Model, provides the requirements for creating a new loan application submission file based on the redesigned Form 1003. This specification contains the conditionality, cardinality, implementation notes, and other business information necessary to implement the redesigned Form 1003 in DU.

The DU Spec, along with other supporting information like an implementation guide and test case suite, can be found on the Technology Integration page for DU.

The ULAD maps the data fields from the redesigned Form 1003 to the MISMO v3.4 Reference Model dataset. This mapping document clarifies Form 1003’s redesigned field names and their corresponding MISMO v3.4 data points.
