Debt Ratios for Residential Financing
The ratio of debt to income is a tool lenders use to determine how much money is available for a monthly mortgage payment after all your other monthly debts are fulfilled.
About the qualifying ratio
Typically, underwriting for conventional mortgages requires 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.
For these ratios, the first number is how much (by percent) of your gross monthly income that can be spent on housing. This ratio is figured on your total payment, including homeowners' insurance, HOA dues, Private Mortgage Insurance - everything.
The second number in the ratio is the maximum percentage of your gross monthly income that should be applied to housing expenses and recurring debt together. Recurring debt includes car payments, child support and monthly credit card payments.
- 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
