You can save yourself a lot of wheel-spinning if you take a minute to figure out how much mortgage you can afford. Generally, a lender will want your monthly mortgage payment to total no more than 29% of your monthly gross income (that\’s your monthly income before taxes and other paycheck deductions are taken out.) You also need to consider current loan interest rates. The lower the interest rate, the more expensive the home you\’ll be able to afford.
