Question 1

What is debt-to-income ratio (DTI)?

Accepted Answer

DTI is the percentage of your gross monthly income that goes toward monthly debt payments. It is one of the key metrics lenders use to evaluate loan eligibility. A lower DTI indicates better financial health.

Question 2

What is the difference between front-end and back-end DTI?

Accepted Answer

Front-end DTI only includes housing costs (mortgage/rent). Back-end DTI includes all monthly debt payments (housing + car loans + student loans + credit cards). Lenders evaluate both ratios.

Question 3

What DTI do mortgage lenders prefer?

Accepted Answer

Most conventional mortgage lenders prefer a back-end DTI below 43%. An excellent DTI is below 36%. FHA loans allow up to 50% DTI. Some lenders may approve higher DTIs with compensating factors like large down payments.

Question 4

How can I improve my DTI ratio?

Accepted Answer

Two ways: (1) Increase income — get a raise, take a side job, or add co-borrower income. (2) Decrease debt — pay off loans, reduce credit card balances, or avoid taking new debt before applying for a mortgage.

Question 5

Does DTI affect credit score?

Accepted Answer

DTI ratio itself does not directly affect your credit score (FICO doesn't use it). However, the factors that create a high DTI — high debt balances and high credit utilization — do negatively impact your credit score.
