A new automated underwriting run using corrected or changed borrower, property, credit, or loan data.
An AUS resubmission is a new automated underwriting run completed after submitted borrower, property, credit, or loan data is corrected or materially changes.
The updated run replaces reliance on an earlier data snapshot and produces revised findings or feedback. Depending on the change, the assessment can remain the same, add requirements, improve, become ineligible, or move to a manual-review path.
A favorable AUS result is valid only for the file represented in that submission. If qualifying income falls, debt rises, the appraisal changes value, or the loan product changes, the old assessment may no longer describe the mortgage being closed.
Resubmission protects data integrity. It makes the automated analysis reflect the current application and gives the lender updated messages to verify. System and program rules may allow defined tolerances or exceptions for certain changes, so not every small difference is handled identically; the lender must apply the rules for the actual AUS and loan path.
The term also explains why a preapproval is not frozen. Borrower decisions and transaction updates can cause a rerun even after the file previously looked favorable.
Resubmission can occur during preapproval, after a purchase contract, during underwriting, after appraisal, and near closing. The lender may rerun the casefile many times as the scenario becomes more complete.
The last valid findings or feedback used for the loan should match the final borrower, property, and mortgage terms under the applicable system requirements. A lender cannot knowingly close one scenario while relying on materially different data submitted earlier.
| Changed information | Why it matters to AUS |
|---|---|
| qualifying income or employment | affects repayment capacity and documentation messages |
| debt, credit score, or credit report | affects ratios and risk assessment |
| assets, down payment, or reserves | affects cash-to-close and financial strength |
| property value, address, type, or occupancy | affects collateral and eligibility |
| loan amount, rate, term, or product | affects payment, ratios, pricing, and program fit |
| borrower added or removed | changes the parties and qualifying profile |
| corrected data entry | makes the system analyze the facts the lender can document |
A borrower receives a favorable AUS result, then finances a car before closing. The new auto payment appears on an updated credit report and must be included in the mortgage analysis.
The lender updates the liability and resubmits the file. If the higher debt still supports a favorable result, underwriting continues with the revised findings. If the result changes, the lender may need a lower mortgage amount, more qualifying income, another eligible program, manual review if permitted, or a denial.
Avoiding surprises is more useful than trying to preserve an outdated result.
AUS findings are the output. Resubmission is the act that generates updated output.
A final credit check is one event that may reveal new debt or credit changes. The lender may then resubmit AUS if the new information affects the file.
A conditional approval is a lender status. Resubmission can support, modify, or invalidate the assumptions behind that status.
A re-underwrite is broader. It may involve renewed human review as well as a new AUS run.
