The housing market is behaving strangely. The peak in the market was around 2006; it went down for three years and if it behaved the same way it had in the last cycle, it would continue going down for years more. But then it had a sudden and sharp turn-around that we rarely see in this market, in the spring of 2009, and that seems to coincide with the American Recovery and Reinvestment Act, which created also the Homebuyer Tax Credit. And the recovery lasted about as long as the tax credit lasted.
