Part the Housing and Economic Recovery Act of 2008 is a tax credit for those buying a home for the first time. It's not exactly free money for you. Rather, it's a chance to get a $7,500 interest-free loan from Uncle Sam. And you get 15 years to pay it back.

To be eligible, you must meet the following requirements:

• Be buying your first home (rental properties and vacation homes purchased in the past don't count against you, but if your spouse owned a home before, that does count against you)
• Purchase the home between April 9, 2008 and July 1, 2009
• Not have income greater than $75,000 (single) or $150,000 (married)

The credit of $7,500 can be taken by eligible taxpayers on their 2008 or 2009 tax return. A credit is the best type of tax benefit because it reduces your tax liability dollar for dollar, wiping out $7,500 of taxes you otherwise would have paid. And if your tax bill is less than $7,500, you can get the difference refunded to you.

You don't get to keep the money forever, though. You'll have to pay back $500 each year on your tax return, for 15 years. But there's no interest on the $7,500 you received up front, so it's still a good deal. The bottom line is that the government wants to offer up some money for those buying their first homes, and let them pay it back over time.
