Understanding DTI Ratio Rules
The 28% Rule
Housing costs (mortgage + taxes + insurance) should not exceed 28% of gross monthly income.
The 36% Rule
Total debt payments (housing + all other debts) should stay below 36% of gross monthly income.
FHA Exception
FHA loans allow DTI up to 43% (sometimes 50% with compensating factors like high credit score).

- ✓ Don't take on new debt before applying for a mortgage
- ✓ Consider increasing income (side job, raise)
- ✓ Extend loan terms to lower monthly payments (but pay more total interest)
- ✓ Use our Affordability Calculator to find your price range
