Debt-to-income ratio (DTI)

Debt-to-income ratio compares monthly debt payments with gross monthly income. The front-end ratio uses the housing payment alone. The back-end ratio adds other debts such as car, student loan and minimum card payments. Lenders use DTI, along with credit and other factors, to decide how much a borrower can borrow.

Why agents care

DTI explains why two buyers with the same income can afford very different homes. Helping buyers see their DTI early, privately, lets you set a realistic search range without discussing their finances in detail.

Example

Example: $8,000 gross monthly income, a $2,400 housing payment and $800 in other debts gives a front-end DTI of 30% and a back-end DTI of 40%.
