How to compute the mortgage payment you can afford

Industry guidelines indicate that a consumer should spend about 28% of his monthly income on housing. If your combined family monthly income is $6,000, you can afford a mortgage payment (PITI) of $1,680. (Other payments. like credit card and car payments, installment loans, etc., should not exceed 36% of your gross family monthly income.)
