Purchasing bank owned property off market

[Ryan Oldenhage]

Has anyone had any success and/or tips for purchasing bank owned property not listed for sale? I've targeted a few homes that are bank owned but not listed for sale yet. I've sent numerous letters to the asset managers for the bank on record and never received a response. I wasn't sure if anyone has had any luck doing this, has knowledge that they can't sell it directly and it's a waste of time, or maybe has a few pointers.
