What is your technique on acquiring note tapes/pools? (open)

[Cameron York]

Real estate note investing is a all about relationships with investors, banks, etc. So What I would like to know is what is your way of acquiring these notes? how do you personally contact banks/investors? What are the best routes? Any secret techniques that maybe the average investor just doesn't think of? Im open to all/different advice/tips from anyone who is willing to shed some of their note investing knowledge.
