Debt Ratios for Home Lending

Lenders use a ratio called "debt to income" to determine the most you can pay monthly after your other monthly debts have been paid.

About the qualifying ratio

For the most part, conventional loans need a qualifying ratio of 28/36. FHA loans are a little less strict, requiring a 29/41 ratio.

The first number in a qualifying ratio is the maximum percentage of gross monthly income that can be spent on housing costs (including principal and interest, PMI, hazard insurance, taxes, and homeowners' association dues).

The second number in the ratio is the maximum percentage of your gross monthly income that should be applied to housing costs and recurring debt together. Recurring debt includes things like car loans, child support and credit card payments.

Examples:

With a 28/36 qualifying ratio

  • Gross monthly income of $2,700 x .28 = $756 can be applied to housing
  • Gross monthly income of $2,700 x .36 = $972 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $2,700 x .29 = $783 can be applied to housing
  • Gross monthly income of $2,700 x .41 = $1,107 can be applied to recurring debt plus housing expenses
