Debt Ratios for Residential Financing

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

Understanding the qualifying ratio

Typically, underwriting for conventional loans requires a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.

In these ratios, the first number is how much (by percent) of your gross monthly income that can go toward housing costs. This ratio is figured on your total payment, including hazard insurance, homeowners' dues, Private Mortgage Insurance - everything.

The second number is what percent of your gross income every month that should be applied to housing expenses and recurring debt. Recurring debt includes things like auto loans, child support and credit card payments.

Some example data:

28/36 (Conventional)

  • Gross monthly income of $8,000 x .28 = $2,240 can be applied to housing
  • Gross monthly income of $8,000 x .36 = $2,280 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $8,000 x .29 = $2,320 can be applied to housing
  • Gross monthly income of $8,000 x .41 = $3,280 can be applied to recurring debt plus housing expenses
