For those following economic trends, the past 18 months are notable primarily for two reasons. First, the U.S. housing market, long seen as overvalued by alternative economists and even powerful economic institutions including the International Monetary Fund (IMF), finally went from boom to bust. Over the span of a few months, housing in some markets depreciated by as much as 30%, and some economists estimate that losses may ultimately reduce value by as much as 50% in some cities.
