“Nearly 10.7 million, or 23 percent, of all residential properties with mortgages were in negative equity as of September, 2009. An additional 2.3 million mortgages were approaching negative equity, meaning they had less than five percent equity. Together negative equity and near negative equity mortgages account for nearly 28 percent of all residential properties with a mortgage nationwide.”

“The distribution of negative equity is heavily concentrated in five states: Nevada (65 percent), which had the highest percentage negative equity, followed by Arizona (48 percent), Florida (45 percent), Michigan (37 percent) and California (35 percent).”
So, two-thirds of the people with mortgages in Nevada owe more than their property is worth; nearly half in Arizona.
