An opinion piece from the WSJ argues that the current bust is following a traditional pathway and is now past the inflection point:
Most people forget that the current housing bust is nearly three years old. Home sales peaked in July 2005. New home sales are down a staggering 63% from peak levels of 1.4 million. Housing starts have fallen more than 50% and, adjusted for population growth, are back to the trough levels of 1982.
Furthermore, residential construction is close to 15-year lows at 3.8% of GDP; by the fourth quarter of this year, it will probably hit the lowest level ever. So what’s going to stop the housing decline? Very simply, the same thing that caused the bust: affordability
The next question is: Even if home sales pick up, how can home prices stop falling with so many houses vacant and unsold? The flip but true answer: because they always do.
In the past five major housing market corrections (and there were some big ones, such as in the early 1980s when home sales also fell by 50%-60% and prices fell 12%-15% in real terms), every time home sales bottomed, the pace of house-price declines halved within one or two months.
The explanation is that by the time home sales stop declining, inventories of unsold homes have usually already started falling in absolute terms and begin to peak out in “months of supply” terms. That’s the case right now: New home inventories peaked at 598,000 homes in July 2006, and stand at 482,000 homes as of the end of March. This inventory is equivalent to 11 months of supply, a 25-year high – but it is similar to 1974, 1982 and 1991 levels, which saw a subsequent slowing in home-price declines within the next six months.
