Just getting started

I am just getting started in real estate. I am currently living in buffalo, but am moving to atlanta in the next 60 days to start mentoring with someone. I am trying to “get a leg up” before I move down there so I can hit the ground running. I would appreciate any and all advice. Also, is it premature of me to start focusing on building my buyers list and how critical is it to have one established before I actually start buying houses?
