Empty Nests: 18.6m of 129m U.S. Housing Units Vacant

Some sobering housing stats:

Of the 129m housing units in America, 18.6m stand empty. At 2.9%, the home-owner vacancy rate, which measures the share of vacant homes for sale, has reached its highest point since measurement began in 1956. At the end of the first quarter there were 2.3m empty homes on the market, an increase of more than 160,000 from the end of 2007. There is a vicious circle: the huge number of houses on the market pushes home prices down, and as prices decrease, mortgages become harder to refinance, leading to more foreclosures, vacancies and so on. The more homes are on the market, the less chance that prices will stabilise.
