Very informative link, however it was dated with prices as of June 2007, ie pre subprime meltdown. 6 months later we are already at a price that the article predicted in 5 years. So maybe the bottom has arrived, and you can start to get your feet wet. Deductible interest and build equity.
But wait, those are the high end homes, I guess if you are looking for closer to median or below median there is still pain ahead. I should have made myself more clear earlier.
