Personally i think there is no substitute for trying to create a great business first. It will become much easier to invest your money without the stress of eating, housing, having fun etc. Because, you have decided to get into real estate the next logical step might be in starting a business/ getting a job that will support your knowledge and understanding of real estate investing. For example. I am an agent who works almost exclusively with investors. I used to analyze deals before being in the industry but now finding and analyzing deals is one of the most important parts of my job. Thus i have gotten 1000% better at it. After my clients buy a building my relationship with them allows me to see first hand their experience in managing the property. In many ways i am with them for the wins and loss's without having to spend my own money. Then when it comes time to sell i am there to help them through that process. If they are flipping a property i likely helped them comp the home on the purchase and on the sale. This has helped me learn the process of flipping a home again without losing my own money.
The best part is that i am saying this only from the perspective of being an agent and there are a ton of jobs in real-estate. You could look at fields in Title work, Management, rehabbing/construction, development, lending, deal sourcing, coaching, airbnb services, tech/software, asset preservation, Closing and so on and so fourth and have a similar outcome.
last should you get your license? Only if your pursuing a job that requires one.
