Debt Ratios for Residential Lending

The debt to income ratio is a tool lenders use to calculate how much money can be used for your monthly home loan payment after all your other monthly debt obligations are fulfilled.

Understanding your qualifying ratio

For the most part, underwriting for conventional mortgages needs a qualifying ratio of 28/36. An FHA loan will usually allow for a higher debt load, reflected in a higher (29/41) qualifying ratio.

For these ratios, the first number is the percentage of your gross monthly income that can be spent on housing. This ratio is figured on your total payment, including homeowners' insurance, homeowners' dues, PMI - everything that constitutes the full payment.

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

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
