Brendon,
Everyone in this thread is right. The Designated Broker who accepts the legal responsibility to supervise your licensed activity is fully accountable to the State regulators for your conduct and transactions.Your Errors and Omissions coverage, advertisting, contracts, MLS membership (if the office participates in MLS), the Realtor status, NAR, state and local boardmemberships are all tied into the Designated broker. I have been an Associate Broker in California and am currently a licensed Associate Broker in Idaho. Also in every state I am aware of, the Broker owns the agent listings.
Regarding flipping houses, as a Licensed RE agent you MUST disclose your status as a licensee in accordance with state regulations, usually to all the parties. You can act as principal but must inform your Broker and operate within your Agent agreement with the Broker.
As a principal, you may cross statelines. As an agent you are restricted by the law of the state in which the property is located for any transaction in which you are not a principal.
My answer is not comprehensive, as this is an exhaustive topic of study and education. Like those comments above, If you choose to earn your RE agent license, take that duty and your duty to your Broker seriously.
Good luck in choosing your path.
