This is the most common question I get asked! Your payment amount is calculated by your income. Traditionally, lenders like to stay between 44%-45% on your debt to income ratio. Some lenders may be able to go higher if your credit score is higher!
For example; lets say you make $5k a month. Your car note is $400 and your proposed home payment is $1500 monthly. Under this scenario, you would qualify for a $225k home.
Not bad considering what monthly rent is around here!
