'The Housing Market Still Isn’t Rational'

For the fans of Robert Shiller:

The Housing Market Still Isn’t Rational: Home prices have been climbing. They have risen 27 percent nationally since 2012, even more in places like San Francisco. But why worry? If you accept the efficient markets theory — and believe that real estate is an efficient market — then these prices are based on “new information,” even if you don’t know what that information is.
The problem with this kind of thinking is that the efficient markets theory is at best a half-truth, as a voluminous literature on market anomalies shows. What’s more, even that half-truth is grounded mainly in the stock market, which attracts professional investors who sometimes do make the market behave efficiently.
The housing market is another matter. It is far less rational than even the often irrational stock market...[explains why]...
The bottom line is that there is no reason to assume that the real estate market is even close to efficient. You may want to buy a house if you love it and can afford it. But remember that you cannot safely rely on “comparable sales” to judge that the price is fair. The market isn’t efficient enough for that.
