Hello,
I'm an Investor/Agent and I just recently got my Florida Real Estate license. Let me see if I can answer some of the questions posted:
#1. If you are out of state I would recommend purchasing the Book Real Estate Practices and Principles by Linda Crawford. (I would get it used in good condition) most of the topics are on the classroom test and state test. Study the book and answer the questions at the end of the chapters and you will be ready for the online class. You WILL pass with flying colors.
#2. I second to Bob Hogue good program.
#3. Once you are licensed you have to work under a licensed Broker in order to have your license "active" in DBPR. DBPR is a division that keeps track of licenses.
#4. Being active is valuable in order to have MLS access which you would have to join an association. I'm in Pinellas County which I had to pay about $845.00 to join the association.
#5. Find an investor friendly Brokerage there are quite a few of them but you get what you pay for. For example most Keller Williams organizations provide leads for the Agent. Marketing costs so the expense will be filtered to the Agents.
