Frequently Asked Questions
Your DTI ratio is the percentage of your gross monthly income that goes toward paying required monthly debt payments. Formula: DTI = Total Monthly Debt Payments / Gross Monthly Income.
Front-end DTI measures housing costs alone (mortgage principal, interest, taxes, and insurance) against gross income. Back-end DTI measures ALL debt obligations combined (housing + credit cards, auto loans, student loans) against gross income.
Conventional conforming mortgages generally require a back-end DTI of 43% or lower (up to 45%–50% with automated underwriting approval). FHA loans can permit up to 50% DTI, and VA loans typically benchmark around 41%.
No. DTI only includes recurring contract debt payments that appear on credit reports: mortgages, auto loans, student loans, personal loans, and minimum monthly credit card obligations.
Pay off small installment loans, eliminate high credit card balances, refinance or consolidate existing debt at lower monthly rates, or add a co-borrower to increase recognized household income.
