John,
it is certainly possibly to pick up properties at 60-65% of market value.
The problem is which ones. You have to know how to do your research.
I have a good friend who is currently working for a company that is buying at the auctions, but they just ran out of money. He is looking to partner with someone with cash. He would be willing to show you the ropes, work side by side, with him, and he can show you the websites they use to get info, etc. You could even go with him to the auction.
However, be prepared to do this full time, the auctions now are starting around 10am and finish around 4 or 5. You may end up waiting several hours for "your" property to come up.
Give me a call or email and I can put you in touch with him.
If you are interested in doing "part time", I would suggest looking into short sales. you can pick up properties for almost as cheap as at the auctions.
Would be happy to speak with you about short sales, as well.
