Non-QM lending and the ATR/QM rule, explained

"Non-QM" gets used casually to mean "less regulated" or "riskier" lending — bank-statement loans for the self-employed, interest-only products, loans for borrowers just outside conventional debt-to-income limits. What it actually means, legally, is narrower and worth understanding on its own terms.

The Ability-to-Repay rule applies to (almost) every mortgage

Under 12 CFR § 1026.43 (part of Regulation Z), a creditor generally cannot make a covered mortgage loan without making a reasonable, good-faith determination — based on verified and documented information, not an assumption — that the borrower has a reasonable ability to repay it, considering income, employment, credit history, debt obligations, and the loan's own terms. This Ability-to-Repay (ATR) requirement applies broadly to mortgages secured by a dwelling; a small set of loan types (open-end credit like a HELOC, timeshare loans, reverse mortgages, and certain temporary/bridge loans) are excluded from ATR entirely, not "non-QM."

What "Qualified Mortgage" status actually adds

A Qualified Mortgage (QM) is a specific category of loan that's presumed to satisfy the ATR requirement, giving the lender stronger legal protection against a borrower later claiming the ATR determination wasn't properly made. Under the General QM definition at § 1026.43(e)(2), a loan generally has to keep its APR within a specific margin above the Average Prime Offer Rate (a benchmark based on comparable transactions) to qualify, along with other requirements (no risky loan features like negative amortization, a cap on points and fees, and documented income/debt verification).

Non-QM: the ATR requirement, without the QM safe harbor

A non-QM loan is one that, for whatever reason — a higher APR than QM allows, a loan feature QM excludes, or a borrower whose income doesn't fit standard documentation (a self-employed borrower using bank statements instead of tax returns, for example) — doesn't meet the General QM definition. Critically, this does not exempt the loan from the underlying ATR requirement. The lender still has to make, and be able to document, a genuine, good-faith determination that the borrower can repay it; they simply don't get the extra legal presumption that QM status provides if that determination is ever challenged. A responsibly-run non-QM lender still verifies income and ability to repay — just through different documentation than a conventional loan might use — while an irresponsibly-run one might skip real verification and rely on the loan simply not needing to meet QM's specific box-checking.

What to actually check with a non-QM originator

Ask directly how your ability to repay was actually verified — what documentation was used, and whether that determination was made in good faith based on real, verified information rather than assumed from the property's value alone (a pattern sometimes called "asset-based" lending in its more responsible form, and a real ATR violation in its irresponsible form). Our own standard treats this as its own checkable point specifically for originators who do non-QM business (see our standard, point 9) — marked N/A, honestly, for an originator who only originates conventional, QM loans, since the question genuinely doesn't apply to them.
