Turn DU and LPA findings into an organized verification checklist.

Short answer: The decoder helps you read and organize official AUS messages. It does not connect to Desktop Underwriter or Loan Product Advisor, change loan data, rerun AUS, or guarantee a particular recommendation.

What the decoder helps organize

Blocking messages

Separate the findings that appear most relevant from informational or follow-up messages.

Possible issue categories

Review data-entry, credit, income, asset, property, and eligibility possibilities without treating them as confirmed causes.

Verification steps

Create a checklist of facts, documents, entries, and current requirements that need confirmation.

Escalation questions

Prepare focused questions for the lender, AUS help desk, processor, loan officer, or authorized underwriter.

How to use this instrument

• Run the official AUS through the lender-approved system and redact unnecessary sensitive data before using this tool.
• Enter or paste only the relevant findings and known file facts.
• Review each possible cause as a verification item, not as a guaranteed diagnosis or fix.
• Correct information only in the authorized loan system, rerun the official AUS there, and follow the resulting current findings and lender direction.

See practical use cases

• Organize findings when a file is not receiving the expected recommendation
• Separate possible data-entry, credit, income, asset, property, and eligibility issues
• Prepare a focused question for the lender, AUS help desk, or underwriter
• Track changes before rerunning the lender’s official AUS

Expected output: An organized troubleshooting checklist. The decoder does not connect to DU or LPA, alter a loan file, or issue an AUS result.

Correct information only in the authorized loan system and follow the official findings returned after the lender-approved AUS is rerun. The decoder is informational workflow support, not an AUS engine or underwriting decision.
