What happens next: We'll show you three affordability scenarios from conservative to maximum, each with different debt-to-income ratios and monthly payment breakdowns.

Understanding Debt-to-Income (DTI) Ratios

Front-End DTI (Housing Ratio)

This is your total monthly housing payment (principal, interest, taxes, insurance, PMI, HOA) divided by your gross monthly income.

Example: If your housing payment is $2,000 and your monthly income is $7,000, your front-end DTI is 28.6%.

Back-End DTI (Total Debt Ratio)

This includes your housing payment plus all other monthly debt obligations (car loans, credit cards, student loans) divided by your gross monthly income.

Example: If your total debts are $2,500 and your monthly income is $7,000, your back-end DTI is 35.7%.
