Debt Ratios for Home Lending

Lenders use a ratio called "debt to income" to decide your maximum monthly payment after you've paid your other monthly loans.

About your qualifying ratio

For the most part, underwriting for conventional loans needs a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) ratio.

The first number in a qualifying ratio is the maximum percentage of your gross monthly income that can be applied to housing (including mortgage principal and interest, private mortgage insurance, hazard insurance, property tax, and HOA dues).

The second number in the ratio is what percent of your gross income every month which can be spent on housing costs and recurring debt together. Recurring debt includes things like auto loans, child support and monthly credit card payments.

For example:

28/36 (Conventional)

  • Gross monthly income of $6,500 x .28 = $1,820 can be applied to housing
  • Gross monthly income of $6,500 x .36 = $2,340 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $6,500 x .29 = $1,885 can be applied to housing
  • Gross monthly income of $6,500 x .41 = $2,665 can be applied to recurring debt plus housing expenses
