Frequently Asked Questions
- Most conventional lenders require a back-end DTI (all debts ÷ gross income) of 43% or less. FHA loans may allow up to 50%. Front-end DTI (housing only) should be under 28%.
- The rule of thumb that you can afford 3× your annual income is conservative — and intentionally so. It provides a comfortable buffer and avoids being "house poor." Many buyers stretch to 4–5×.
