This is my quick tip to you :)The first Friday of each month there is a Bigger Pockets meet up held at the Summit Keller Williams not far from you.

She is fantastic and her husband is the Keller Williams broker.

If you are looking to be a top agent that will take some time, I suggest reading Gary kellers "Millionaire real estate agent" to get a good perspective of what it takes to produce.

Best, BobThe folks in the St Pete area that made this work for us:Ron Puckett of Ron Puckett Construction (GC)Rob Van Stronder of Keller Williams  David Kweller of Kweller Mechanical (air conditioning)Jillian Biltz of Urban Upgrades (colors and interior design)There are many others who helped along the way.  

I have 10 long term rentals and 8 fix and flips right now and I would not have gotten half of those if I was not an agent.I would read Gary Kellers books and learn all you can about real estate.

read gary keller's millionaire areal estate investor book

I'd go with Keller Williams to start because they have some pretty decent training they put you through.

Choosing Century 21 over Keller Williams is not going to make or break your career.

My understanding is that Keller Williams actually encourages their agents to invest in real estate. 

@James Williams   The very best way to answer all your questions is to Simply waltz into your nearest C 21 or Keller Williams or Re max office and speak to the recruiting broker tell them that you want to pursue a career in RE and they will answer all your questions help you get started with the education etc etc.
