All those "great" buys from six months ago, one year ago, two years ago, etc. aren't looking like such great buys anymore. Prices continue to plummet, especially on raw land and there is a ways to go. As long as the price of land continues to fall, so will the price of the houses and condos.
I saw a pending lot sale in WC PH II for $145k (ask price, not pending price) that is 80% off the high water mark based on a the sale of the lot next door in 2005. Some asking prices in Watersound Beach are well under $250k and not selling, the preserve under $100k, cypress dunes under $100k, etc.
With prices continuing to fall, foreclosures will continue to hit the market as more people finally decide to throw in the towel as their properties languish on the market.
