Debt Ratios for Residential Financing

The ratio of debt to income is a tool lenders use to calculate how much money is available for your monthly mortgage payment after all your other monthly debt obligations have been met.

How to figure your qualifying ratio

Most conventional loans require 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.

The first number in a qualifying ratio is the maximum percentage of gross monthly income that can be spent on housing costs (this includes principal and interest, private mortgage insurance, hazard insurance, property tax, and HOA dues).

The second number is the maximum percentage of your gross monthly income that should be applied to housing costs and recurring debt together. Recurring debt includes vehicle loans, child support and credit card payments.

Some example data:

A 28/36 ratio

  • Gross monthly income of $3,500 x .28 = $980 can be applied to housing
  • Gross monthly income of $3,500 x .36 = $1,260 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $3,500 x .29 = $1,015 can be applied to housing
  • Gross monthly income of $3,500 x .41 = $1,435 can be applied to recurring debt plus housing expenses
