Borrower earns $7,500/mo. At 43% max DTI with no other debts, max housing payment?

Correct answer: $3,225

Maximum housing payment = Gross Monthly Income × Maximum DTI = $7,500 × 43% = $3,225. With no other debts, the entire DTI allowance can go toward housing (PITI). Note: the 43% figure was the original General QM DTI cap, which was eliminated in the 2021 revision. However, many lenders and programs (including FHA) still reference 43% as a guideline. Conventional lenders may allow up to 45-50% with compensating factors like reserves or high credit scores.
