I have purchased (live) 6 properties from various auction companies. Auction.com is by far the worst.
1. Their "estimated opening bid" is a total work of fiction by some kid behind a computer. Case-in-point: I'm currently looking at a property where the owners owe $417k on the primary and they estimate it to open for $260k.
2. The last time, they had an estimate of 117k and at the auction, they said it had an opening bid of 117k but would not take less than 134k. Strange.
3. When they do get the real opening bid from the bank (usually 2 days prior to the auction), they rarely post it. Other companies post it and what it sold for at auction.
4. They won't divulge what the property really sold for.
I have actually skipped auctions run by Auction.com just to avoid the circus that they are trying to create.
