Example: 28/36 DTI with moderate debts
- Gross monthly income = $7,000; existing monthly debts = $600; front-end DTI = 28%; back-end DTI = 36%.
- Max housing (front-end) = 7,000 × 0.28 = $1,960.
- Max total debt (back-end) = 7,000 × 0.36 = $2,520 → subtract $600 existing debts → Max housing (back-end) = $1,920.
- Qualifying housing payment = $1,920 (the lower of $1,960 and $1,920).
- Front-end DTI ≈ 1,920 ÷ 7,000 ≈ 27.4%; back-end DTI ≈ (1,920 + 600) ÷ 7,000 ≈ 36%.
