FAQ

What is DTI ratio?
Debt-to-Income ratio = (total monthly debt payments ÷ gross monthly income) × 100. Lenders use this to assess ability to repay. Most conventional loans require DTI ≤ 43%; FHA loans allow up to 50%.
What is the front-end ratio?
Front-end ratio is just the housing costs (PITI) ÷ gross monthly income. Most lenders prefer this below 28-31%.
What is the 28/36 rule?
Housing expenses should not exceed 28% of gross income, and total debt payments should not exceed 36%. This conservative guideline was standard before higher DTI limits became common.
How much should my down payment be?
20% down avoids PMI (private mortgage insurance). With 3-5% down via FHA or conventional loans, you pay PMI. A larger down payment means a lower loan amount and better interest rates.
