Frequently Asked Questions

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

DTI is your total monthly debt payments divided by your gross monthly income, expressed as a percentage. For example, if you pay $2,000/month in debts and earn $6,000/month, your DTI is 33%. Lenders use this to gauge your ability to take on new debt.

What debts are included in DTI calculation?

Include: mortgage/rent, car loans, student loans, credit card minimum payments, personal loans, child support/alimony. Don't include: utilities, insurance (unless part of mortgage), food, entertainment, or other living expenses.

What DTI do I need for a mortgage?

Conventional loans typically require DTI under 43%, with ideal being under 36%. FHA loans may allow up to 50%. The housing portion (front-end DTI) should ideally be under 28%. Lower DTI can mean better rates and terms.

How can I lower my DTI to qualify for a mortgage?

Pay off credit cards or loans (especially high-payment ones), increase your income, avoid new debt, consider refinancing high-payment loans, and hold off on major purchases before applying. Even small reductions can help.
