Not sure a property auction is an ideal environment for a first time buyer. If you're taking out a relatively large loan the lender is going to want to know what you're buying, have it valued, etc. You are going to want to get it surveyed, searches done, etc. and there simply isn't time to do most of this in advance of an auction, and if it's your first time you don't want to rush into it. Hence they are, as said, the playground of those who have the money sitting around and, to an extent, can take some risk with it.
The risks of not getting the property, and having to right off the cost of getting yourself into a position to bid is high too.
I would look for a property in reasonable order that's had some old farts living in it since the '60's and requires some modernising. That's what I did with my first house purchase. Bought in what seemed like a bouyant market at the time and still doubled my money.
Estate agents will bend over backwards to find you something in the current climate.
