Two related questions
Regulation Z section 1026.43 governs ability-to-repay requirements for covered dwelling-secured transactions. The creditor generally must make a reasonable, good-faith determination of the consumer's repayment ability. Qualified-mortgage provisions provide defined pathways with legal protection when their conditions are satisfied. A non-QM loan is not automatically unlawful, and QM status does not guarantee that a borrower will never struggle. [1]
This September 27, 2026 review uses the CFPB's current regulation and official commentary. The December 2020 General QM rule replaced the former 43% debt-to-income ceiling with a pricing framework. That historical change should not be described as a new event, and the old 43% number should not be presented as the universal current General QM limit. Other QM categories have their own conditions. [2]
Underwriting remains substantive
The general ATR analysis considers documented income or assets, employment when relied upon, the covered mortgage payment, simultaneous loans, mortgage-related obligations, existing debts, debt-to-income or residual income, and credit history. The exact treatment follows the regulation and applicable exceptions. An automated approval score cannot replace the required consideration and verification merely because it predicts default reasonably well. [1]
Recommended file design separates evidence from calculations and conclusions. Preserve the income source, period, adjustments, verification date and reason for excluding unusual deposits. Link property taxes, insurance, association charges and other mortgage obligations to the correct property. Review simultaneous financing so the apparent down payment does not conceal another repayment obligation.
Variable income creates an especially important distinction between average earnings and reliable capacity. A high annual average can conceal several low-cash months. A lender's chosen treatment should be consistent, documented and tested. The legal requirement and the institution's risk appetite may justify different thresholds, but a policy overlay should not be mislabeled as an express statutory limit.
Price-based General QM is not simply the note rate
For a standard first-lien General QM in the applicable larger-loan category, the APR must be less than APOR plus 2.25 percentage points at the relevant rate-setting date. The 2026 loan-size threshold for that category is $137,958. Smaller loans, subordinate liens and certain manufactured-home transactions have different thresholds. Use the current indexed schedule rather than a number copied from a prior year's checklist. [1][3]
The APR includes relevant finance charges and is not necessarily the contractual interest rate. General QM also has product-feature, term, points-and-fees and underwriting conditions. The pricing threshold for General QM eligibility must be distinguished from the higher-priced test that separates a safe harbor from a rebuttable presumption for relevant QM loans. For a standard first-lien General QM, the latter generally turns on a 1.5-percentage-point spread. [1][3]
Worked comparison: three pricing outcomes
Hypothetical example: assume a $300,000 first-lien fixed-rate mortgage, a 6.00% APOR on the correct rate-setting date, and satisfaction of every other General QM condition. An APR of 7.40% has a 1.40-point spread and falls below the standard higher-priced threshold. An APR of 7.80% has a 1.80-point spread: it remains below the 2.25-point General QM eligibility ceiling but has a different liability-protection analysis.
An APR of 8.25% has a 2.25-point spread and fails this General QM pricing condition because equality is not below the ceiling. That does not itself establish that the loan violates ATR or cannot qualify under another applicable pathway. It means this particular General QM route is unavailable. The example is not a quote, an approval or an evaluation of an actual borrower.
This boundary makes change control important. A late fee change can move APR across a threshold even when the note rate is unchanged. A rate lock, extension or repricing event needs the correct APOR reference date. The final compliance determination should use the consummated terms and supported calculation, not the initial marketing illustration.
Payment mechanics and adjustable rates
The regulation's General QM underwriting method uses the maximum rate that may apply during the first five years after the first regular periodic payment is due, with specified amortization rules. Calendar detail matters: a first reset near the end of that window can fall inside it even when a product is casually described as fixed for five years. The official commentary provides examples demonstrating this issue. [1]
Recommended testing therefore includes first-payment dates, delayed first payments, rate caps, index assumptions and step-rate changes. Payment software should expose the contractual schedule and the qualifying schedule separately. A low introductory payment is not sufficient evidence of repayment capacity at the qualifying payment.
For illustration, a $300,000 balance amortized over 30 years at 6% produces approximately $1,799 in monthly principal and interest; at 8%, approximately $2,201. Taxes, insurance and other obligations are additional. The roughly $402 difference shows why a teaser-rate calculation can distort affordability even before household expenses are considered.
Controls, tradeoffs and reassessment
Recommended controls include an explicit coverage decision, documented ATR or QM pathway, current threshold tables, fee classification review and independent recalculation of boundary cases. Monitor exceptions and repurchases by originator and channel. A low early delinquency rate cannot demonstrate legal compliance, especially in a young portfolio with rising balances.
QM eligibility can improve marketability and reduce legal uncertainty, but designing exclusively around eligibility boundaries can encourage misplaced confidence. A profitable and compliant product still needs realistic affordability, servicing and stress analysis. Non-QM lending can meet useful borrower needs while requiring different evidence, pricing and investor expectations.
The conclusion would change with binding amendments, a relevant court interpretation or different loan facts. An executive order or proposal does not itself replace the current rule. For a specific file, corrected income, undisclosed debt or a fee change can alter the result. The governance standard is the ability to recreate both the underwriting determination and the precise legal pathway from dated evidence.
