New Debt Discovered Before Closing: What Ability-to-Repay Requires

A borrower may buy a car, open a credit card, or co-sign a loan while a mortgage is moving toward closing. That can change monthly obligations and the ability-to-repay picture. The exam issue is more precise than ‘the lender must always rerun everything’ or ‘the lender can ignore new debt.’ Regulation Z requires a reasonable and good-faith assessment based on required factors and the information the creditor knows when it underwrites the loan.

Debt belongs in the ATR analysis

Under 12 CFR 1026.43(c), the creditor must consider the consumer’s current debt obligations, alimony, and child support, along with income or assets, the payment on the covered loan, simultaneous loans, mortgage-related obligations, and credit history. Debt examples include student loans, auto loans, revolving debt, and existing mortgages that will not be paid off at or before consummation. For covered QM transactions, the creditor must also verify specified information under the applicable rule.

The rule calls for reasonably reliable third-party records to verify current debt obligations, alimony, and child support. A credit report is a common source, but lenders may use other reliable records as appropriate. The creditor should distinguish a balance from a monthly payment and understand whether an obligation will continue, be paid off, or change after a temporary deferral or forbearance.

What if the debt appears after the credit report?

The CFPB’s official commentary gives an important boundary: Regulation Z does not generally require a creditor to re-underwrite a loan because it learns of a new debt or mortgage-related obligation after the underwriting determination, if the creditor did not know of it during underwriting. The commentary explains that a creditor must consider obligations known when the loan is underwritten. This rule prevents the ATR standard from becoming an unlimited duty to discover every later change before consummation.

That is not permission to ignore information the creditor actually has. If an MLO learns before closing that the borrower has taken on a large new monthly payment, the lender should follow its underwriting and closing controls. The new information may affect the institution’s reasonable, good-faith determination, program eligibility, investor requirements, or representations. It may also signal that previously submitted information is no longer accurate. The specific legal and operational result depends on when the lender learned it and what its procedures require.

Known before underwriting versus learned later

Temporary payment arrangements

A debt in deferment or forbearance is still part of the analysis. The creditor should consider whether the obligation is likely to affect the consumer’s ability to repay based on the payment that will apply after the temporary period and on relevant facts, including when the period ends. A temporary $0 payment should not automatically be treated as a permanent absence of debt if a substantial payment will begin shortly after closing.

Likewise, a mortgage scheduled to be paid off by a sale may be treated differently from an ongoing mortgage, but the creditor should have a factual basis—such as an existing sale contract—and document the reasoning. A borrower’s informal statement that a debt will be paid later is not always enough to remove it from the calculation.

MLO workflow and file evidence

Loan originators are often the first people to hear about a new auto lease, a co-signed obligation, or a change in income. The MLO should not advise the borrower to conceal the obligation or promise that it does not matter. The appropriate step is to update the loan team using the lender’s process, document when the information was received, and provide any requested statements or payoff evidence. The underwriter, not the MLO acting alone, determines how the obligation is treated under the lender’s approved methodology.

• Record the date the creditor learned the information and the source.
• Confirm the payment, term, status, and whether the obligation is expected to be paid off.
• Use reasonably reliable third-party evidence where required.
• Apply consistent treatment to similar obligations and document exceptions.
• Follow lender requirements for refresh credit, re-underwriting, loan-program eligibility, and closing certification.

Exam takeaways

For a test question, identify what the creditor knew at the time of underwriting. If the obligation was known, it belongs in the required ATR analysis. If it was unknown and arose after underwriting, Regulation Z does not impose an unlimited automatic re-underwriting rule for every new obligation. Then note that lender policies and other requirements can still require action. A temporary deferral does not necessarily make a debt irrelevant; consider the post-deferral payment and timing.
