Lenders don't necessarily view education debt as a bad thing. Your ability to buy a house when you owe student loans depends largely on your credit score and how much money you make. By Janet Bodnar, Editor-at-Large September 26, 2007 I'm in my early twenties and I'm thinking about buying a house. I don't have any credit-card debt, but I owe about $20,000 in student loans. Will that hurt my chances of getting a mortgage? Not necessarily. When you apply for a mortgage, lenders don't just look at how much you owe; your income is also a factor. Mortgage lenders traditionally follow what's known as the 28/36 rule: No more than 28% of your monthly gross income should be dedicated to your mortgage payment, property taxes and insurance. And your total debt payments should equal no more than 36% of your gross income. Two other factors are also important: The more money you put down, the less risk the lender takes on and the more likely you are to get a mortgage. Especially in today's market, in which lenders are looking for squeaky-clean borrowers, a bigger down payment makes you more attractive.

When credit scores are calculated, student-loan debt is viewed more favorably than credit-card debt.

Student loans, mortgages and car loans -- which require you to pay a fixed amount every month -- are installment loans. Credit cards -- which let you control your monthly payments -- are revolving loans. Owing a lot of money in installment debt isn't going to hurt your credit score as much as maxing out your credit cards. Nevertheless, young adults often get themselves into trouble with their student loans, either because they can't afford to make the payments or simply elect not to. But new grads typically build their credit history based on a credit card or two plus student loans, so it's important not to fall behind. If you're struggling to pay off your federal Stafford loans, you have several options: If you can't find a full-time job or you experience some other kind of economic hardship, buy time by asking your lender about deferring your loan repayment.

A bill just passed by Congress would phase in repayment terms that are even more generous for borrowers who need help. See A Break on College Costs for more information.
