According to First American CoreLogic, a real estate information company, 10.7 million households had negative equity in their homes. That is they were under water because they owed more on their mortgages than the properties are worth. The proportion is 23% or one in four homeowners. Mark Fleming CoreLogic's chief economist points out that having negative equity lowers labor mobility and in that way makes it harder to sell the house to look for jobs elsewhere. This is happening in Michigan and other states and is a discouraging sign for improving the job numbers. In this way the poor prospects in housing, banking bad loans in commercial real estate with tight bank lending, and the already high 10.2% umnemployment rate intersect to make 2010 pose significant risks for the economy.
