Once again the danger of not understanding the data. The $625,000 was for the Former Model with tons of upgrades, a prime location and a much larger than average yard. Better properties always sell for premium prices. Not sure about the others but it looks like “this loser” actually paid a more than fair price even in light of the other cheaper priced model matches.
Prices are softening but the real estate market is a pretty darn efficient market. It’s because of the information systems created by Realtors. Homes typically sell for what they should while homes priced incorrectly rot on the shelves. If there were no Realtors and no Multiple Listing Service which is not a public utility but rather a system paid for and supported by Realtors homes would be very difficult to sell at any price.
