Debt-to-income ratio (DTI)
Your total monthly debt payments divided by your gross monthly income. Lenders use it to judge how much mortgage you can handle, typically capping it around 43%.

DTI tells a lender how much of your income is already spoken for. Lenders look at two versions: the front-end ratio (just the housing payment) and the back-end ratio (housing plus all other debt), with conforming loans generally capping the back end near 43% — sometimes higher with compensating factors. A lower DTI both improves approval odds and leaves more comfortable room in your budget.
Aim for a back-end ratio (all debts) at or below 36%, with 43% the common ceiling for conforming loans and the housing portion alone near 28%. The lower your DTI, the better your approval odds and the rate you are offered.
Add up your monthly debt payments — mortgage, car, student loans, credit-card minimums — and divide by your gross (pre-tax) monthly income. If debts total $2,100 and you earn $6,000 a month, your DTI is 35%.
Recurring debt: the proposed housing payment, auto and student loans, credit-card minimums, and any child support or alimony. It excludes everyday costs like utilities, groceries and insurance that are not reported as debt.
Work backward from your income and debts to the home price and mortgage you can responsibly afford.
Check whether your income, debts and down payment qualify you for the loan you want.
Turn a down-payment percentage into dollars and see whether you clear the 20% PMI threshold.
