How Much Can You Afford?

The answer to that is a function of two things: How much you can borrow and how much of a down payment you can save. As a rule of thumb, your annual mortgage payment, taxes and homeowner's insurance shouldn't exceed 28% of your gross income. Then determine how much cash you have for a down payment, leaving yourself enough left over to pay those pesky closing costs, which can add up to 3% to 5% of your total home's value (plus a little something extra for emergency repairs once you move into your new home).
