I despise this company and everything they stand for. They've made life miserable for anyone trying to purchase foreclosures. They charge needless fees that you can avoid when you purchase a fannie mae, freddie mac or HUD property. Also, you have to use a credit card to bid on their site. If you make the mistake of using a bank card they place a $2500 hold on your account which takes a while to remove. This is not outlined or disclosed ahead of time and can cause a lot of anguish if you don't keep large amounts of cash in your checking account.
I've bid on several houses and invested in several but I've never had any success with auction.com and hope the banks see the mistake they are making by using them.
