Ratio of Debt-to-Income

Lenders use a ratio called "debt to income" to determine your maximum monthly payment after you've paid your other recurring loans.
About your qualifying ratio
For the most part, conventional mortgage loans need 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 is the percentage of your gross monthly income that can go toward housing. This ratio is figured on your total payment, including hazard insurance, HOA dues, Private Mortgage Insurance - everything that makes up the full payment.
The second number in the ratio is what percent of your gross income every month that should be spent on housing expenses and recurring debt together. Recurring debt includes auto/boat payments, child support and credit card payments.
For example:
28/36 (Conventional)
- 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
