Debt Ratios for Residential Lending

Your debt to income ratio is a tool lenders use to determine how much of your income is available for a monthly mortgage payment after all your other monthly debts are fulfilled.

About your qualifying ratio

For the most part, conventional mortgages require 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 your gross monthly income that can go to housing costs (this includes principal and interest, PMI, homeowner's insurance, taxes, and HOA dues).

The second number in the ratio is what percent of your gross income every month which can be spent on housing expenses and recurring debt together. Recurring debt includes vehicle payments, child support and monthly credit card payments.

Some example data:

With a 28/36 qualifying ratio

  • 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
