Lenders use a ratio called "debt to income" to decide your maximum monthly payment after your other monthly debts have been paid.

About your qualifying ratio

In general, conventional mortgages require a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.

The first number is how much (by percent) 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, PMI - everything.

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

Some example data:

With a 28/36 qualifying 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
