Debt-to-Income Ratio 2026: Improve DTI for Mortgage Approval
Quick Answer
Debt-to-income (DTI): monthly debts / gross income. Front-end DTI: housing ≤28%. Back-end: all debts ≤43-50%. Lenders require <43%; excellent credit can push to 50%. Improve DTI by paying down cards, eliminating debts, or increasing income.
Front-End DTI
(Mortgage + tax + insurance + HOA) / gross monthly income ≤28%
Example: $5,000 gross income × 28% = $1,400 max housing payment.
Back-End DTI
(Housing + auto + credit cards + student loans + personal loans) / gross income ≤43-50%
Example: $5,000 income, $1,850 total debts = 37% DTI (acceptable).
How Lenders Calculate
- Auto loans: Actual payment
- Credit cards: 2-5% of balance (typically 2-3%)
- Student loans: Actual payment or 0.5-1% balance
- Mortgage: Lender calculates based on proposed loan
Improve DTI Before Applying
- Pay down credit cards: Reduce balance = lower estimated payment
- Pay off auto loan: Eliminate $300/month
- Pay off student loans: Eliminate payment
- Increase income: W-2 raise, documented 2-year history
- Avoid new debt: No new car/personal loans for 6 months
Mortgage Shopping
- 43% DTI: Conventional, excellent credit (>740)
- 50% DTI: Stretched, may have higher rates/fees
Better to improve to <43% before applying.
