Housing Wire reports a Mortgage Bankers Association (MBA) official predicts the 4.5 million distressed properties on the market will prevent a full housing market recovery for four to five years.  Michael Fratantoni, vice-president of economics and market research, says some areas may experience recovery sooner, like Washington, D.C. and Texas. New York, Illinois, Florida, California and New Jersey have the highest percentage of shadow inventory, and may take longer to recover.  Home prices should stabilize by December 2011, and the MBA predicts mortgages will hit 6.2 percent by the end of 2012.  The average 30-year fixed mortgage rose to 5.06 percent in March.
