The bubble collapse started a little over a year ago in the OC. In San Diego, it started almost two years ago.
In five years, when we look back and factor in inflation, the peak and corner turn will be obvious.
Two years to bottom, then a short languish there and in 3-4 years from now, bottom pricing will remain but sales volume will increase. Which might just be in time for the Alt-A 5 year ARMs to kick it in the groin.
