ATR/QM on a first mortgage: the HFA exemption and what the QM price test means for you

Nearly every first-time program produces a qualified mortgage, which is why the 43% DTI myth persists. The rules that actually shape a first loan are the eight ATR factors, FHA’s APR-based QM test, the 3% points-and-fees cap, and an exemption that covers HFA loans and DPA seconds.

Ability-to-Repay is the rule that decides how an underwriter must verify a first-time buyer, and Qualified Mortgage is the label that tells the lender it did enough. Most first loans fall in the safe zone, but the edges are exactly where this profile lives.

Eight factors, verified from third-party records

The lender must consider and verify current income or assets, current employment, the monthly payment on this loan and on any simultaneous loan — your DPA second counts — property taxes, insurance and HOA dues, other debts, the resulting debt-to-income ratio or residual income, and credit history. “Verify” means pay stubs, W-2s, tax transcripts and bank statements, not a stated figure. This is why a gift or a DPA second must be documented before the approval is final: the second lien’s payment, if any, goes into the ratio. A 0% deferred DPA second adds no payment; a repayable second at $75 a month does, and that $75 can tip a tight file.

Which QM test your loan faces

FHA loans use HUD’s own QM definition: safe-harbor status when the APR is no more than the average prime offer rate plus 1.15 points plus the annual mortgage insurance premium, rebuttable-presumption status above that. Conventional loans — including HomeReady, Home Possible and Conventional 97 — use the General QM since the GSE “patch” ended in 2021: the APR may not exceed APOR by more than 2.25 points for loans of typical size, the term is capped at 30 years, and there is no interest-only, negative-amortization or balloon feature. The 43% debt-to-income limit was removed from the General QM definition; automated underwriting routinely approves first-time buyers at 45% to 50% DTI with strong compensating factors. Our DTI guide explains where the practical ceilings sit.

The 3% points-and-fees cap

For a QM, total points and fees generally may not exceed 3% of the loan amount on loans above roughly $130,000 (the threshold is indexed each year), with higher percentage limits on smaller loans. The cap includes origination charges and broker compensation but excludes the FHA upfront premium and bona fide discount points within limits. On a $200,000 first loan, a lender charging a 1.5% origination fee plus a $1,500 broker fee is near the line; ask for the points-and-fees calculation if Section A of your Loan Estimate looks heavy.

The HFA exemption

Loans made under a program administered by a state housing finance agency, and DPA loans from HUD-designated assistance providers, are exempt from ATR entirely. In practice the HFA first mortgage is still underwritten to FHA or agency standards because that is who buys it, so the exemption changes little for the buyer. What it does mean is that a 0% deferred second from the HFA will not be subjected to a separate ability-to-repay analysis — the assistance is designed to be affordable by construction, and the lender will not refuse it for ATR reasons.

What to check

• Document the gift and the DPA second early: any payment on a simultaneous second lien goes into the ATR ratio.
• Ask which QM test applies — FHA’s APR-plus-MIP test or the General QM price test — and whether the loan is safe harbor.
• Request the points-and-fees total if origination and broker charges on the Loan Estimate approach 3% of the loan.
• Do not treat 43% DTI as a wall; agency automated approvals commonly run higher with reserves and a solid credit profile.

Frequently asked questions

Does ATR/QM stop a lender from approving me at 48% DTI?

No. The General QM definition replaced the 43% limit with a price-based test in 2021, and FHA’s QM rule never used a fixed ratio. The lender must still make a reasonable, good-faith determination that you can repay, using verified income and debts, and the automated systems of Fannie Mae, Freddie Mac and FHA frequently accept 45% to 50% with compensating factors. Whether you should carry that payment on take-home pay is a different question.

Is my state HFA down payment loan subject to Ability-to-Repay?

Generally not. Regulation Z exempts loans made under programs administered by a housing finance agency, which covers both the HFA first mortgage and its subordinate assistance loans. The first mortgage is nonetheless underwritten to FHA, VA, USDA or GSE standards because the agency sells or insures it that way. Confirm with the lender how the second’s payment, if any, is counted in your ratios.
