10 tips to buy or sell real estate in 2010

But don't be too jubilant. A recent report by Deutsche Bank estimates that by 2011, about 48 percent of all U.S. mortgages will be underwater. Short sales and foreclosures will continue to put pressure on home prices in 2010 as they work their way through the pipeline slowly. It was apparent in 2009 that lenders were holding back much of their foreclosure inventories and REO, or real estate-owned property, in an effort to keep values up.

Meanwhile, housing's biggest economic driver -- the job market -- continues to stagnate as averageunemployment remains high, at around 10 percent. So it's no surprise the new year will ring in another buyer's market, though with far more upside than in 2009. With that as a backdrop, here are 10 real estate tips for homebuyers and owners in 2010.

The $8,000 first-time homebuyer tax credit program that helped jump-start the real estate market in 2009 has been extended into 2010 and expanded. First-time homebuyers who sign a binding contract to buy a home by April 30, 2010, and close on it by June 30, 2010, qualify. The program's maximum income limits have jumped from $75,000 to $125,000 for individuals and from $150,000 to $225,000 for couples.
