Economist: Buttonwood Dropping a Brick

Property was indeed a great investment at a time when financing was easy and recessions were occasional and mild. But that world has disappeared for a while. Even low interest rates may not help, as the Japanese example has illustrated over the past 20 years.
The naive belief that American house prices could not fall at the national level has been exposed by the current crisis. The belief that property prices must rise over periods of a decade or more may also prove to be false. Figures from Robert Shiller of Yale University show that real American house-prices were lower in 1945 than they were in 1900, for example.
