Understanding DTI Ratio

DTI is the percentage of your gross monthly income that goes toward debt payments. Lenders use it to assess your ability to handle additional debt. Front-end DTI covers housing costs only; back-end includes all minimum debt obligations. Most mortgage lenders require a back-end DTI of 43% or less.

DTI Guidelines by Loan Type

Conventional loans: typically 43% max back-end DTI, 28% front-end preferred. FHA loans: 43–50% back-end DTI allowed with compensating factors (reserves, excellent credit). VA loans: 41% guideline but flexible. Jumbo loans: often stricter, requiring DTI below 38–43%.

Improving Your DTI

Two levers: reduce monthly debt obligations or increase qualifying income. Paying off a car loan, student loan, or credit card balance before applying for a mortgage can meaningfully shift your DTI. Documenting all income sources (side gigs, rental income, consistent overtime) can increase the denominator and lower your ratio.
