There are certainly many inputs into a sale price and the affect of the past several years declining market. The homes that tend to be most affected are in the top brackets and the lowest. In the top brackets many sellers have grown impatient and are anxious to move on. In the lower price ranges, foreclosures are taking their toll on market value. In the specific case of a house selling for $105K in 2005, that house is probably valued at about $95K by today's market. Remember, every buyer wants a "steal".
