How big of a FHA Loan Can I afford?

Your monthly costs should not exceed 31% of your gross monthly income for a FHA Loan. Total housing costs often lumped together are referred to as PITI. 

P = Principal

I = Interest

T = Taxes

I = Insurance

Examples:

Monthly Income x .31 = Maximum PITI
$3,000 x .31 = $930 Maximum PITI

Your total monthly costs, or debt to income (DTI) adding PITI and long-term debt like car loans or credit cards, should not exceed 43% of your gross monthly income.

Monthly Income x .43 = Maximum Total Monthly Costs
$3,000 x .43 = $1290
$1,290 total - $930 PITI = $360 Allowed for Monthly Long Term Debt

FHA Loan ratios are more lenient than a typical conventional loan.  FHA does offer some flexibility in the debt-to-income ratio requirements under the right circumstances.
