Investing With a Broker's License?

[Jack Fernandes]

I was curious as to how licensed brokers (in California, or anywhere similar) handle fee splitting when buying properties for themselves. Presumably as a broker/agent, if you present the selling agent with a buyer, you are entitled to your portion of the fee. What if you are a licensed broker representing yourself? Do you still get to split the fee? How is this usually handled/negotiated? 

On the other end, what if you're a broker but are selling your own house? How are fees negotiated here? Do you get to save out on all fees? 

Thank you in advance for your patience and for answering my question thoughtfully and respectfully.
