Debt Ratios for Residential Lending

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

About your qualifying ratio

In general, 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 amount (as a percentage) of your gross monthly income that can be spent on housing (including principal and interest, private mortgage insurance, hazard insurance, property tax, and homeowners' association dues).

The second number in the ratio is what percent of your gross income every month which can be applied to housing expenses and recurring debt. For purposes of this ratio, debt includes credit card payments, vehicle payments, child support, and the like.

For example:

A 28/36 qualifying ratio

  • 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
