Debt Ratios for Residential Financing
Lenders use a ratio called "debt to income" to decide your maximum monthly payment after you have paid your other recurring loans.
About the qualifying ratio
Most underwriting for conventional mortgage loans requires a qualifying ratio of 28/36. FHA loans are less restrictive, requiring a 29/41 ratio.
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 homeowners' insurance, HOA dues, PMI - everything.
The second number is what percent of your gross income every month that can be spent on housing costs and recurring debt. For purposes of this ratio, debt includes payments on credit cards, auto loans, child support, etcetera.
- Gross monthly income of $4,500 x .28 = $1,260 can be applied to housing
- Gross monthly income of $4,500 x .36 = $1,620 can be applied to recurring debt plus housing expenses
With a 29/41 (FHA) qualifying ratio
- Gross monthly income of $4,500 x .29 = $1,305 can be applied to housing
- Gross monthly income of $4,500 x .41 = $1,845 can be applied to recurring debt plus housing expenses

Don't forget these ratios are just guidelines. We'd be happy to go over pre-qualification to help you determine how large a mortgage loan you can afford.
