How do Realtor/Investors fairly split commission with Broker?

[Rebecca Ramos]

Hi BP family,

I going to start taking Maryland RE licensing classes this month and have several questions.

1. Once I'm a licensed Realtor as an Investor, what should I look for when choosing a Realtor/Investor friendly Broker?
2. What would the approximate Broker/Realtor commission fee be if I am also an RE Investor?
3. Does my Broker receive a commission if I purchase or sell a property as an Investor?
4. How do Realtors who are also experienced Investors do this legally and ethically?
5. Are there certain criteria in being a successful Realtor and RE Investor you can suggest?

Please excuse my many questions. I know this is a good place to get feedback, so I thank you in advance for your reply and suggestions.
