Connecting to REO agents

[George Ramsay]

So I went to a reia meeting Monday night and the guru pitching his stuff was Andy heller. I don't want to buy his whole system but a lot of it was based on relationships with REO agents. Which brings up a flaw in my business which is acquisition.
So I'm looking for tips tricks, and scripts that I can use when submitting a contract for a post foreclosure. Not only to try and convince the bank to deal with me but also to see if there is anything in their "hidden inventory" that would be a good fit.
One thing to note is that I'm not asking to deal with big banks like wells frog or BOA, this strategy would be developed around dealing with local banks.
Just looking for insight from investors that have relationships with REO agents and how they developed those relationships.
