harsh.
btw 38% of 70K is 2215 / month, not too far off, and it depends what her other debt is.
Fuck did you go to the same school?!?! You are calculating that before any taxes.
Happy Bday sucka
A quick Google search (from multiple sites) yields the same info:
Q: How do I know if I can afford this Mortgage payment?
A: There are two ratios you should check: your debt to income ratio, called DTI, which is calculated by dividing your total monthly income (before taxes) by your monthly fixed expenses. Lenders prefer a ratio of 33/38 which means 33% of your monthly income is dedicated to your housing costs and after adding in your other monthly expenses, the debt should not exceed 38% of your monthly income. PITI refers to your total monthly mortgage payment calculated by adding the monthly principal, interest, taxes and insurance for your loan.
