Ratio of Debt-to-Income
The ratio of debt to income is a formula lenders use to calculate how much of your income is available for a monthly mortgage payment after you meet your other monthly debt payments.
About your qualifying ratio
Usually, conventional mortgage loans require a qualifying ratio of 28/36. FHA loans are a little less strict, requiring a 29/41 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 applied to housing expenses and recurring debt together. Recurring debt includes things like auto 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
