Getting a license comes down to opportunity, personal goals, and personality type. I started as an agent because I work well with people and had an opportunity to start with a top producer at a boutique firm which gave my immediate and invaluable exposure as an agent. It has also allowed me to get paid and learn about the real estate business at the same time which is an ideal placement for me. That being said if you have no connections to get your foot in the door as an agent you will most likely end up at KW in a sea of other agents. Plus you have to be able to eat a lot of crap and manage other peoples emotions if you plan on operating in the residential space. Getting your license can be a great way to make money and learn about RE, but is not necessarily the best path if your end goal is to be an investor. If getting your license aligns with your short and long term goals I would say go get it. However if you are passing up a good income paying job for a commission only position in an extremely competitive field with no experience I would advise turning to books, podcasts, and local networking events to learn while still collecting a steady paycheck.
P.S. Working as an agent takes time to build the right connections, client list, and skill sets to become a producer. I would say it takes a minimum of five years even with good connections to become successful in your market. So if you are thinking of just getting in and out this is not the path to take.
Hope this helps.
