GUS Lender Test Environment (LTE)

Guaranteed Underwriting System (GUS) Lender Test Environment (LTE)

USDA Rural Development Single Family Housing Guaranteed Loan Program (SFHGLP) offers a Guaranteed Underwriting System (GUS) lender test environment (LTE) to support our valued lending partners. USDA Rural Development (RD) Single Family Housing (SFH) lenders with an active Lender Participation Agreement (Form RD 3555-16 or Form RD 1980-16) and an active GUS User Agreement can gain approval and access to GUS LTE by following the below “Steps to Gaining Approval and Access to GUS LTE”. GUS LTE will allow approved lenders to:

  • Test loan origination system’s compatibility and performance with the GUS automated underwriting system. (Import Fannie Mae DU MISMO 3.4 XML files or manually enter application data (recommend testing both)
  • Get familiar with our GUS interface and application workflow. Test Document upload and retrieval, display fields, and overall GUS functions.
  • Utilize the test environment for staff training.

Steps to Gaining Approval and Access to GUS LTE

  1. Confirm your lending organization has an active Lender Participation Agreement and “Production” GUS Agreement
  2. Use of the Guaranteed Underwriting System Lender Test Environment (GUS LTE) requires TEST eAuthentication/Login.gov accounts to be created and used in accessing the test environment. Each lender will need to identify their Lender TEST Environment (LTE) GUS Security Administrator(s) (SA). This/These individuals are required to establish a unique USDA test Login.gov account. See LTE System Access and Security Guide located in GUS LTE Resources.
  3. Complete, execute and return the "Addendum to the GUS USER AGREEMENT for the GUS Lender TEST Environment (GUS LTE)" (see GUS LTE resources below) and any questions, to SFHGSystemIntegration@usda.gov.

Helpful hints to execute and return the addendum:

  • Production GUS eAuthentication/Login.gov credentials should not be used.
  • Your production GUS SA does not need to be your LTE SA; however, we recommend they communicate.
  • Ensure your LTE SA’s TEST eAuth/Login.gov USER ID, name, phone and email is listed on the addendum (required).
  • Ensure the proper authorized party within your organization executes the document.

*Only officials who are authorized to represent your organization may execute the Addendum.

  1. Once your executed addendum is received by USDA’s GUS Systems Integration team, we will:
    • Review Addendum for approval.
    • Set up your approved LTE SA (lender test environment security administrator) access to LTE Application Authorization Security Management (AASM). LTE SA will need to provide and manage your testing team’s access to GUS LTE. See LTE System Access and Security Guide located in GUS LTE Resources.
    • Provide confirmation you have been approved to begin testing by email along with the USDA Lender Security Administrator Instructions for adding GUS LTE roles and manage your testing team’s access to GUS LTE.
  2. Happy testing! For more information view GUS LTE User Guide located in GUS LTE Resources. If you have additional questions email SFHGSystemIntegration@usda.gov.
