Buying off Auction.com without agent or do most use an agent?

[Jared McCullough]

I am fairly new to using Auction.com and although my last rental was bought of their it was somewhat of a fluke because I had originally submitted a cash offer the day it went to auction so my real estate agent I normally used handled the offer submital through Auction.com. Although the whole process was a royal pain in the *** I find that most of the foreclosures I am looking into tend to make it here before they hit the price point that I am looking at paying. 

The latest is a 3/1 in which I would like to make an offer on but as I never "bid" on the first one and my agent did it for me I was wondering if this is required or I guess more so advised. Based on what I read it seems not and I guess I could just register. If I am to do it myself what should I be watching out for that would be typically handled by the buying agent?

The main thing I noted was getting title insurance which for the one I am looking at is paid for by the "Seller" which was the same as my prior purchase.
