📖 Real Scenario
Kevin earns $95,000/year ($7,917/month). His debts: car payment $450, student loan $380, credit card minimums $120. Total: $950/month. His DTI before mortgage: 12%. He can add up to $2,400/month in mortgage payment and stay at 42% DTI — qualifying for a $340,000 loan.
Everything You Need to Know
Q: What DTI do I need to get approved?
Conventional loans: 43-45% max back-end DTI. FHA: up to 50-57% with compensating factors. VA: typically 41% guideline but flexible with residual income. USDA: 41% standard. The lower your DTI, the better your rate and approval odds.
Q: What counts in DTI calculation?
Monthly debt minimums: mortgage PITI, car loans, student loans, credit card minimums, personal loans, child support, alimony. Does NOT count: utilities, groceries, phone, insurance, subscriptions, medical bills (unless they appear on credit report).
Q: How do I lower my DTI fast?
1) Pay off small debts entirely — eliminating a $200/month car payment drops DTI significantly. 2) Don't take on new debt before applying. 3) Pay down credit card balances to reduce minimums. 4) Add income (part-time work counts after 2 years of history).
Q: What's the difference between front-end and back-end DTI?
Front-end (housing ratio): only your mortgage payment ÷ income. Lenders want this under 28-31%. Back-end (total DTI): ALL debt payments including mortgage ÷ income. Lenders focus most on back-end. FHA limits: 31/43 (front/back), though exceptions exist.

The part almost nobody publishes free
Prices and rates are widely reported. Whether a lender says yes is not. In the complete 2025 federal record, denial rates across the 100 largest FHA lenders ran from 1.8% to 78.7% — same programme, same year.
And it is not simply who applies where: standardizing on state, loan amount, income, debt-to-income and loan-to-value, applicant mix explains only a 2.7× range in expected outcomes.
