Debt Ratios for Residential Lending

Lenders use a ratio called "debt to income" to decide your maximum monthly payment after your other monthly debts have been paid.

About the qualifying ratio

Usually, conventional mortgages require a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.

The first number is the percentage of your gross monthly income that can go toward housing. This ratio is figured on your total payment, including hazard insurance, homeowners' dues, Private Mortgage Insurance - everything.

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

Some example data:

28/36 (Conventional)

  • Gross monthly income of $4,500 x .28 = $1,260 can be applied to housing
  • Gross monthly income of $4,500 x .36 = $1,620 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $4,500 x .29 = $1,305 can be applied to housing
  • Gross monthly income of $4,500 x .41 = $1,845 can be applied to recurring debt plus housing expenses
