Count me as another one who had a negative experience with auction.com. This was in 2011, when I was the winning online bidder for a small house in Phoenix for $23,000. I gave a $5,000 certified check to the escrow agent as instructed.
Maybe 2 weeks go by, and I get a phone call out of the blue from same agent telling me to pick up my $5,000 check because the property had been relisted and sold to someone else. Huh?
He was vague about what happened, but come to find out that he "forgot" to send in my $5,000 required down payment in time, and auction.com simply erased my winning bid as if it never happened. I got my $5,000 back but raised hell with state agencies on the deception. Of course, auction.com contracts are all about protecting themselves and making sure they don't have to pay any penalties to you for any liability on their part.
I did get their law department involved, but they only responded because they had to answer to the state agencies that I reported them to.
Bottom line, I never did get any legal or financial satisfaction from them except to put their deceit on the record with state agencies. They are scum, stay away.
However, I did buy another foreclosure house from Bank of America right after that for $29,100. BofA was straightforward and easy to deal with, no surprises.
