@Jeremy Ridges - You can obtain a license and just work for yourself as Darren stated. The question you might want to ask yourself isn't 'can I' but 'should I'.
To obtain your license you will have to complete 96 hours of class work and pass the real estate exam. In reality, this is a pretty low bar. Maintaining your license requires you to 1) pay annual fees to KREC and GLAR, 2) complete continuing education each year, 3) purchase E&O insurance, and 4) work under a licensed broker. Said broker may charge desk fees as well as keep a part of any commission you earn.
The time cost is more significant than the financial cost. If you want to be a rehabber, the 96 hours you spend in agent class is time you don't have to learn how to be a better rehabber. For that matter, you could complete multiple deals in 96 hours.
I'm not saying don't become an agent, but you should make sure that doing so really supports your goals. Building a team may be a better approach.
Finally, I'd encourage you to koin KREIA. It's a great place to network and learn.
Good luck!
