Debt Ratios for Residential Financing

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

How to figure the qualifying ratio

For the most part, underwriting for conventional loans needs a qualifying ratio of 28/36. FHA loans are less restrictive, 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. This ratio is figured on your total payment, including homeowners' insurance, HOA dues, Private Mortgage Insurance - everything that constitutes the full payment.

The second number is the maximum percentage of your gross monthly income that should be spent on housing costs and recurring debt. Recurring debt includes credit card payments, car payments, child support, and the like.

For example:

28/36 (Conventional)

  • 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
