Regulation — housing-specific

Dodd-Frank ATR/QM (Sec 1400-1500) — AI underwriting-decision defensibility

The Ability-to-Repay + Qualified Mortgage Rule sets the underwriting-decision floor for every closed-end residential mortgage. When AI produces the underwriting recommendation, the ATR determination must still trace to considered factors, verified data, and defensible reasoning.

What the regulation actually says

"No creditor may make a residential mortgage loan unless the creditor makes a reasonable and good faith determination at or before consummation that the consumer has a reasonable ability to repay the loan … A creditor's determination … shall include consideration of the consumer's credit history, current income, expected income the consumer is reasonably assured of receiving, current obligations, debt-to-income ratio …" 15 U.S.C. §1639c(a) — Truth in Lending Act as amended by Dodd-Frank

"A creditor must verify the information … using reasonably reliable third-party records …" 12 CFR 1026.43(c)(3) — Regulation Z ATR verification

What this means in plain English

Reasonable and good-faith determination is the standard. Not "the model said so." A defensible ATR record must show the eight required factors were considered.
Data must be verified from reasonably reliable third-party records. AI outputs are not third-party records; they consume them.
Liability runs for the life of the loan. Borrower defenses to foreclosure include ATR violations; assignee liability is a real feature of the rule.

What triggers the exposure in the sample

H3 files routed to decline / non-QM during the drift window changed the ATR stance on the ones that closed anyway. Where the AI's DTI or FICO handling drifted, the ATR determination on the resulting loan can be re-litigated years later — assignee liability included.

What the $499 Snapshot shows against this rule

Model-version + input-snapshot record per sampled decision — the "eight factors considered" traceability
Decision-hash binding — the tampering-detectable ATR record
Retention per SR 11-7 model-documentation horizon — matches ATR life-of-loan liability
Independent-verifier signature — the "reasonable and good faith" evidence

How does this help me?

ATR is the rule plaintiff counsel reaches for in wrongful-foreclosure and assignee-liability defense. Dated independent evidence is worth multiples of what it costs.
