Debt Ratios for Residential Financing

Your debt to income ratio is a formula lenders use to determine how much of your income is available for your monthly home loan payment after you have met your other monthly debt payments.

Understanding the qualifying ratio

Usually, conventional mortgages need 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 gross monthly income that can be spent on housing costs (this includes loan principal and interest, private mortgage insurance, homeowner's insurance, property taxes, and HOA dues).

The second number is what percent of your gross income every month that can be applied to housing expenses and recurring debt together. For purposes of this ratio, debt includes payments on credit cards, car loans, child support, etcetera.

For example:

28/36 (Conventional)

  • 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
