Debt Ratios for Residential Financing
Lenders use a ratio called "debt to income" to determine the most you can pay monthly after you have paid your other monthly debts.
How to figure the qualifying ratio
For the most part, underwriting for conventional loans 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.
The first number in a qualifying ratio is the maximum percentage of your gross monthly income that can be applied to housing costs (this includes loan principal and interest, private mortgage insurance, hazard insurance, property tax, and homeowners' association dues).
The second number is the maximum percentage of your gross monthly income which can be spent on housing expenses and recurring debt together. For purposes of this ratio, debt includes credit card payments, vehicle payments, child support, etcetera.
- 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
