I bought a home In Jan 2016 through Auction.com it was a smooth transaction.
I have wasted almost a whole week traveling over a thousand miles and doing my due diligence on 5 different properties listed on Auction.com this past week, only to have them cancel the auction on the day it was scheduled. If their policy is that poor with the people they list for don't expect them to work for you. They work only for the seller you are just a pawn as a buyer.
