Conventional Fannie Mae loans generally require a back-end DTI of 43% to 45% (up to 50% with strong credit and automated underwriting approval).

How can I quickly lower my Debt-to-Income (DTI) ratio before applying for a mortgage?

Pay off small recurring installment loans, eliminate revolving credit card balances, or increase documented gross income with a co-borrower.

Wichtiger rechtlicher Hinweis

Lenders compare gross monthly income to minimum monthly recurring debt payments. Conventional loans prefer total DTI under 43% (up to 45-50% with automated underwriting approval).
