Ideally, you already know how much you can afford to spend before the mortgage lender tells you how much you qualify for. Bankrate's "How much house can I afford?" calculator will help.
By calculating debt-to-income ratio and factoring in a down payment, you will have a good idea of what you can afford, both upfront and monthly.
Though there's not a fixed debt-to-income ratio that lenders require, the standard dictates that no more than 28 percent of your gross monthly income be devoted to housing costs. This percentage is called the front-end ratio.
The back-end ratio shows what portion of income covers all monthly debt obligations. Lenders prefer the back-end ratio to be 36 percent or less, but some borrowers get approved with back-end ratios of 45 percent or higher.
