Debt Ratios for Residential Lending

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

Understanding the qualifying ratio

Usually, conventional mortgage loans need 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 amount (as a percentage) of gross monthly income that can go to housing costs (this includes loan principal and interest, private mortgage insurance, homeowner's insurance, taxes, and HOA dues).

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

Some example data:

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
