Detailed explanation

Debt-to-income ratio (DTI) compares specified monthly debt obligations with qualifying monthly income under program and lender rules.

Underwriting considers the full file. No single income item, score, asset, or property characteristic determines the result by itself, and documentation requirements differ by program and lender.

What this means for you

The calculation may differ from a personal budget and is only one part of underwriting. Confirm which debts and income amounts were included.
