Maybe it's a Magic 8-Ball Nothing to add to the Wall Street Journal story on this:

Goldman’s analysts, Hui Shan and Sven Jari Stehn, project that the national S&P/Case-Shiller home price index has 2.5% to fall before it hits bottom next summer. The Case-Shiller index of prices in 20 large cities is likely to fall 3.5% before hitting bottom in the second half of 2012, they say.
