Home prices are going to decline another 5% to 10% in 2010, according to Mark Zandi, chief economist for Moody's Economy.com.

That's because Zandi expects another 2.4 million foreclosures will continue to flood the market with cut-rate inventory at the same time high-unemployment will limit the number of potential buyers.

The four states with the biggest foreclosure problem -- Florida, California, Arizona and Nevada -- will continue to see the biggest decline in property values. The study expects home prices in Miami, Fort Lauderdale and Orlando to fall by another 30% in 2010.

Of the 100 markets in Moody's annual forecast, Pittsburgh is the only place where home values are projected to increase next year.

But the study predicts the great majority of cities will see home prices growing again in 2011.

"It's clear we're closer to the end of this crash than the beginning," Zandi told Fortune magazine. "We're moving in the right direction, and that's reason for optimism."

Last year's study was pretty accurate. Moody's forecast a 14.5% decline in home values for 2009, and the final figure is likely to come in around 13.2%.
