Debt Ratios for Residential Lending
Lenders use a ratio called "debt to income" to determine your maximum monthly payment after your other monthly debts are paid.
Understanding your qualifying ratio
Most conventional 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) ratio.
The first number in a qualifying ratio is the maximum amount (as a percentage) of gross monthly income that can go to housing costs (including mortgage principal and interest, PMI, homeowner's insurance, property tax, and HOA dues).
The second number is what percent of your gross income every month that can be applied to housing expenses and recurring debt together. Recurring debt includes auto/boat loans, child support and credit card payments.
- 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
