Case-Shiller’s September housing report came out worse than expected, confirming to any doubters that the housing double dip is here.

National home prices dropped 1.5% in September.The new data will worsen Case-Shiller’s already bearish outlook for the housing market.

Earlier this month, it forecast a 7.1 percent drop in prices from Q2 ’10 to Q2 ’11, with price stagnation through Q2 ’12. This is a brutal forecast, which would have wide economic consequences.

Five years after the housing peak, markets in Florida, Nevada and California would remain down around 60 percent.  If you want to move to warm weather this is probably the time to find a buy of a lifetime in Florida, California or Arizona.
