Debt Ratios for Home Financing

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

How to figure your qualifying ratio

Typically, underwriting for conventional mortgages requires a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.

For these ratios, the first number is how much (by percent) of your gross monthly income that can go toward housing costs. 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. Recurring debt includes auto payments, child support and credit card payments.

Some example data:

With a 28/36 qualifying 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
