I went... the marriott conference room was PACKED with people to start, with about 200 people for 15 properties. After time I found most of them are onlookers just to see whats going on. Anyways, 15 properties, around 5 are 3 bedroom (1800 sqft) and the rest of 10 are 2br 1600 sqft homes. Very easy to calculate price because there is only two floor plans.
The 2BR ones were going for around $500k after 5% "premium". The 3BR were going for around $575k on average.
One notable observation was that as buyers won, you can see them leaving, leaving less bidders. The winning price kept sliding by 5-10k after each winning bid. Additionally, there was 22 auctions for 15 properties. because half the winners DQ'd on the loan qualification. One property was won for $615k, and after it came back on the block it was sold for 565k. Most time when winning bidders walk, the subsequent auction price was lower because there is now less people to bid on the property. REDC has countrywide on site to qualify winning bidders, but you dont have to use them during escrow. I don't think you lose the $5k deposit if you dont quality for a loan after you bid, but you forfeit 3% if you drop out of escrow.
Overall you can see buyers were fairly cautious, and the auctioneer was at times flustered due to low bids. The high bid will sit for 4-5 minutes as the auctioneer tries to extract other bids, which was quite annoying. Towards the end, people started leaving and by the last auction I would say more than half the people were gone.
