Ability-to-Repay Rule: Lender Obligations Under Federal Law
The Ability-to-Repay (ATR) rule is a federal mortgage lending standard that requires creditors to make a reasonable, good-faith determination that a borrower can repay a residential mortgage loan before extending credit. Established under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and implemented through regulations issued by the Consumer Financial Protection Bureau (CFPB), the rule applies to virtually all closed-end residential mortgage loans. Its significance lies in the structural safeguard it places on origination practices — directly addressing the underwriting failures that contributed to the 2008 financial crisis.

Definition and scope
The ATR rule is codified at 15 U.S.C. § 1639c of the Truth in Lending Act (TILA) and implemented through Regulation Z, 12 CFR § 1026.43, which was finalized by the CFPB in January 2013. The rule obligates covered creditors to retain documented evidence that they evaluated a borrower's financial capacity using defined underwriting criteria before loan consummation.
Coverage: The rule applies to closed-end consumer credit transactions secured by a dwelling, including purchase loans, refinances, and home equity loans that are not open-end credit plans.
Exemptions: Certain transaction types fall outside the ATR rule's reach, including:
The CFPB retains supervisory and enforcement authority over covered creditors under this rule. The Federal Reserve, OCC, FDIC, and NCUA share examination responsibilities for institutions within their respective charters.
How it works
A creditor satisfying the ATR standard must consider and verify at least 8 specific underwriting factors at the time of origination, as enumerated in 12 CFR § 1026.43(c)(2):
- Current or reasonably expected income or assets — verified through third-party records such as W-2s, tax returns, or bank statements
- Current employment status — confirmed through employer verification or similar documentation
- Monthly payment on the covered transaction — calculated using the fully amortizing payment
- Monthly payment on simultaneous loans secured by the same dwelling
- Monthly payment for mortgage-related obligations — including property taxes, insurance, and HOA fees
- Current debt obligations — inclusive of alimony, child support, and other recurring liabilities
- Monthly debt-to-income (DTI) ratio or residual income — evaluated against documented income
- Credit history — assessed using a consumer report or other available records
The standard does not specify a maximum DTI threshold for general ATR compliance, though the Qualified Mortgage (QM) safe harbor provisions previously capped DTI at 43 percent. Following a 2020 CFPB final rule (85 Fed. Reg. 86308), the General QM definition shifted from a DTI-based threshold to a price-based threshold tied to the Average Prime Offer Rate (APOR).
Creditors must retain verification documentation for at least 3 years following loan consummation, as required under 12 CFR § 1026.25.
Common scenarios
Scenario 1 — Self-employed borrower: A creditor evaluating a self-employed applicant cannot rely solely on stated income. Under ATR requirements, income must be verified through IRS transcripts, 2 years of federal tax returns, or equivalent documentation. Year-over-year income variability must be factored into the capacity assessment.
Scenario 2 — Adjustable-rate mortgage (ARM): For ARMs, the ATR payment calculation uses the fully indexed rate or the introductory rate, whichever is greater, applied to the maximum loan amount at the time of consummation. This requirement prevents creditors from underwriting to artificially low teaser rates.
Scenario 3 — Balloon payment loans: A creditor originating a balloon-payment loan outside of the small creditor safe harbor must calculate repayment ability based on the balloon payment itself, not just the periodic payment schedule. Balloon-payment Qualified Mortgages are limited to small creditors meeting the criteria at 12 CFR § 1026.43(f).
Scenario 4 — Simultaneous second-lien origination: When a creditor originates both a first and second mortgage simultaneously (a piggyback structure), the ATR assessment must incorporate the combined monthly payment obligations for both loans.

Decision boundaries
The ATR rule's most consequential structural distinction is the division between General ATR compliance and Qualified Mortgage (QM) safe harbor status.
| Feature | General ATR | Qualified Mortgage (QM) |
|---|---|---|
| Legal protection | Good-faith compliance defense | Safe harbor (conclusive) or rebuttable presumption |
| DTI requirement | No specified cap | Price-based APR/APOR spread test |
| Points and fees cap | None specified | 3% of total loan amount (12 CFR § 1026.43(e)(3)) |
| Risky loan features | Permissible with documentation | Prohibited (e.g., negative amortization, interest-only for most QM categories) |
| Litigation exposure | Higher — borrower can challenge ATR compliance | Lower — safe harbor limits borrower challenge grounds |
A loan that satisfies QM criteria receives either a conclusive safe harbor (if the APR does not exceed APOR by 1.5 percentage points for first-lien loans) or a rebuttable presumption (if the spread exceeds that threshold). The rebuttable presumption applies primarily to higher-priced mortgage loans as defined under 12 CFR § 1026.43(e)(1).
A borrower who successfully asserts an ATR violation may recover actual damages, statutory damages up to the greater of $4,000 or the sum of all finance charges and fees paid, costs, and attorney fees — or raise the violation as a defense to foreclosure (15 U.S.C. § 1640). The statute of limitations for affirmative ATR claims is 3 years from loan consummation; the foreclosure defense right has no time limit under TILA's recoupment doctrine.
