Home Buyer, Hollywood, CA
There's probably only a dozen or so houses left unsold by the end of the auction (the few that fail to secure financing or meet the bank reserve without enough time to re-auction the same day). At a previous auction (10/07, I didn't stay to the end of the 1/28 auction), they actually auctioned the unsold San Diego houses at the end of the LA auction. I imagine they try the same thing with any unsold LA houses (auction them at the end of the OC/Pomona/San Bernardino auctions). So, by the end of the month, there may not be any unsold houses.
As for prices, they should show up eventually as the sold price when you look up any individual house. I don't know of a collective source of all the prices, although most of the folks in attendance write down all the selling prices, should you know someone who attended.
