I don't believe it is anything but a dead cat bounce, which may indeed go higher because of QE3, but it is not the sign of a fundamental change like the one which occurred in 1997, nor for that matter like the one in the immediate aftermath of WWII. Housing values remain in the high range of historical post-war experience and need to fall further.
Obama has had no commitment to fixing housing, playing around the edges of the issue, and Romney plans to do nothing but let the market fix it, which is probably the best thing to do, as long as he doesn't fiddle with current tax arrangements affecting housing.
The tax changes introduced in 1997 need to find their equilibrium without more interference. The federal government needs to firmly express its commitment to all current tax arrangements affecting housing, including the mortgage interest deduction, in order to calm the housing market and give homeowners, buyers, sellers and financiers the confidence to move forward on a solid basis.
Markets hate uncertainty about rules!
