Peter Schiff argues in this Op-Ed in the Wall Street journal that average US housing prices are still too high:
If we assume the bubble was artificial, we can instead imagine that home prices should have followed a more traditional path during that time. In stock-market terms, prices should have followed a trend line. When you do these extrapolations (see lower line in the nearby chart), a sobering picture emerges. In his book "Irrational Exuberance," Yale economist Robert Shiller (co-creator of the Case-Shiller indices along with economists Karl Case and Allan Weiss), determined that in the 100 years between 1900 and 2000, home prices in the U.S. increased an average 3.35% per year, just a tad above the average rate of inflation. This period includes the Great Depression when home prices sank significantly, but it also includes the frothy postwar years of the 1950s and '60s, as well as the strong market of the early-to-mid 1980s, and the surge in the late '90s.
In January 1998 the 10-City Index was at 82.7. If home prices had followed the 3.35% annual 100 year trend line, then the index would have arrived at 126.7 in October 2010. This week, Case-Shiller announced that figure to be 159.0. This would suggest that the index would need to decline an additional 20.3% from current levels just to get back to the trend line.
Schiff is quite correct. And I would add that the diversion of capital from other industries to housing during the 1998-2006 bubble is one of the reasons why the current recession is so severe. It is unfortunate that the federal government continues to subsidize the home mortgage market.
