What is the best way to find off market properties? Atlanta,San Antonio, N. Carolina?

[Annette Barnett]

I'm in California and looking in Atlanta, San Antonio, Raleigh & Charlotte.

Do commercial agents share their off-market deals with each other?  So that if I worked with one commercial agent, s/he might have access to info about off market deals from other agents?  

What are other ways to find off market deals?  

I am looking for a triplex, quad or larger.
