@Michael Warinner unlike most of the people on this chat (and not knocking on them or their experience by any means), I can probably relate to you the most because I am 22 years old and have contemplated doing exactly what you did and almost did it if my mentors didn’t talk me out of it.
What you should do varies based on what your major is and if you’ll be in any debt after school, but I’ll give you some solid general advice.
If you’re majoring in something what will realistically get you a decent paying job out of school (ie: Engineering, Finance, etc), just go back to school.
There’s two reasons for this:
1) Having a steady cash flow will make it easy for you to both get your credit score up and to save cash for a down payment. Lenders also love a steady cash flow because you are less of a risk than someone who makes commission or gig-based income, and they also prefer someone with a college degree for their job security.
2) You’ll probably my make more money with your degree than as a realtor (at least in the beginning, which is where it counts).
You also do not need a license to make money in this business. You will gain knowledge by actually investing and from mentors whom you will meet throughout your life.
Make sure to network and read books as much as possible.
Just some food for thought.
