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 monthly debts.

Understanding your qualifying ratio

Typically, 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) ratio.

The first number is the percentage of your gross monthly income that can be spent on housing costs. This ratio is figured on your total payment, including hazard insurance, HOA 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 expenses and recurring debt together. For purposes of this ratio, debt includes credit card payments, auto loans, child support, and the like.

Examples:

With a 28/36 ratio

  • Gross monthly income of $8,000 x .28 = $2,240 can be applied to housing
  • Gross monthly income of $8,000 x .36 = $2,280 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $8,000 x .29 = $2,320 can be applied to housing
  • Gross monthly income of $8,000 x .41 = $3,280 can be applied to recurring debt plus housing expenses
