Hi Shray, I'm adding my vote for completing your degree. Switching to a real estate major might not make sense at this point if that means more time/money before you get a degree. Most real estate jobs do not require a real estate-specific degree. But simply having a four-year degree has long-term economic value that will help give you one of the most important ingredients for building wealth: OPTIONS. Not having a four-year degree of some kind closes so many doors that you might want walk through in the future. HR departments are quite ruthless about degree requirements!
Please keep in mind that many entrepreneurs and investors leverage stable, well-paying W-2 jobs while growing their portfolios and businesses (read the excellent Phil Knight autobiography Shoe Dog for a great example of this.) Brian Murray, real estate investor and author of Crushing It In Apartments and Commercial Real Estate, is another example.
One thing you might want to do is ask an advisor to review your transcript to identify whether or not you are eligible for options that could reduce the time/money needed to complete your degree, such as pass/fail CLEP tests. (When I was in college, I took CLEP tests for Comparative Religion and Philosophy - feel free to PM me if you want to know more about how this works!)
I love you are already light years ahead of most of your college peers in terms of business and investing. If you keep up what you are doing AND finish your degree, you will have a very strong base from which to build your life and career. You are off to a great start!
