Susan -
In terms of how to find the great REO deals, let me recommend that you start building relationships with the big REO listing agents.
They control the inventory, and they can help you get your offers accepted over other buyers (and better offers) if they really want to. But, they have to want to.
If you can get your agent license, this will go a long way towards helping you build these relationships. By having your license, you can do all the work on the deal (other than submit the offers to the seller), and then hand your side of the commission to the listing agent.
There is no better way to make a listing agent happy than to do all his/her work, and then hand them all the commission.
Do this once or twice, and they'll start calling you with the great deals...and you won't have to worry about competition getting in your way.
