The answer to this question will vary person-to-person and most college experiences aren't apples-to-apples anyway. The name/brand of your school, your legacy/networks, and quite frankly just random luck will play such huge factors into what path you take out of college. My point to this is not to take any one (or even group of) answer to your question as gospel, including mine.
That said, I'm in a bit of a unique position to lend input to your problem. I dropped out of college when I was 19 to pursue entrepreneurship, went back when I was 23, and then went for my MBA when I was 28 (I like to joke on job interviews that I'm part of a rare subset of "college dropouts who have a masters"). Without getting too much into it here, I was doing extremely well with my business when I dropped out. I already had proven a solid track record of sustainable income while doing the business part-time, and it was very clear to everybody around me (parents, college advisers) that my time was better spent pursuing that business full-time than to finish my last 3 years of college (where best case was probably getting a job making less than I was already making part-time). I had good years with the business -- much better than I would have had doing it in lockstep with school -- but I had to give it up 4 years later due to reasons beyond my control.
My college experience (at least my second one) was a huge negative. I picked a school close to home that didn't have a big brand name, which made finding a job extremely tough. Not to mention that a lot of Corporate America isn't exactly open-minded when it comes to people who took the "non-linear" path to get in front of them (Corporate hiring managers are notoriously risk averse because they'll usually have 100 other candidates who are deemed to be "safer" than you. I'd spend so much time on interviews basically having to defend myself for leaving school to do something else that they'd barely discuss my actual skills or credentials).
I went back for my MBA years later basically as a double-down on what I already had considered to be a bad decision. I was certainly heading in a much more positive direction during grad school, but ironically I might be the only person in the world who got fired for finishing his graduate degree (I got downsized because the company felt they could no longer afford the promotion they had promised me if/when I graduated). While I'm optimistic I'll be back in something in the next few weeks, let the record show that 4 of my first 6 months after getting my masters have been spent unemployed :)
My point in sharing this with you is the following:
1) Is college really worth it? Most likely no, unless you are A) going to a big name school; B) have a significant scholarship, are not paying for it yourself, or if it's at least just like a cheap state school; or C) have family who are going to gift you a career when you graduate. Anything outside those 3 are largely going to be reliant on random walks of luck, which is inherently a sucker's bet.
2) However, you need to be positive that your time is better spent outside of school to justify leaving. If you can already flip houses while in school, then are you 110% positive you can immediately scale that with the added time? I don't just mean that your plan is to read more books and attend more meetings. I mean that if you can flip 2 houses while in school now, then can you immediately flip 6-8 with the time added by removing school?
3) While you could always go back to school later, remember that once you leave the linear educational path that you're probably going to have to defend that decision for the rest of your life, and the majority of people aren't as open-minded as you would hope.
