Short sales are really a chore. I would agree to wait for REO properties. Any home that is at any of the third party auctions are all REO properties that have already passed through the foreclosure process and are lender owned. The homes at the last auction seemed to sell at lower prices then the homes at the auction in June. However if you reviewed all of the San Diego homes at both the August and June auctions, there were very few properties in desireable areas.
Hopefully that will change, OR the lenders will market them appropriately when they put them on the MLS the first time. Most of the properties at these auctions have already been through MLS cycles.
If you are going to purchase at auction do ALL OF YOUR DILIGENCE BEFORE YOU GO TO THE AUCTION.
