@Katie Schlickman Good advice!
Absolutely stay in school. I just graduated, and to be perfectly honest there is a lot of crap in school you will never use. The 4 years seemed to drag, but you also get an experience out of college that fantastic if you seek out opportunities. I traveled the country and the world needing very little money out of my own pocket for all the trips. Those are things that I will remember my whole life.
In the real world it is nice to have something to fall back on. If something ever happens in life I know I can grab a corporate job with a great benefit plan and make my $70k a year no problem. With more experience in life that salary potential only goes up.
That being said if real estate is what you want study finance, accounting, and if possible go after a real estate degree from a school that has a great program. I personally am very happy with my finance degree because I can speak investments with the people who have money and can help me close big deals. Since I know their language but am young, have some experience and am willing to get my hands dirty older investors ready to sit back and let their money work for them through me.
As Katie had said though, I wish I had gotten more involved with local real estate while in college other then just helping to renovate/flip my parents homes. I really wish I would have gotten in with the local developer/residential multi family property owner. If I had that type of management under my belt and could have been in on watching him close deals to build 30 unit and 50 unit complexes in AAA location real estate I would be a lot more comfortable understanding the moving parts as I try to close current deals.
Stay in school but be a hustler at the same time and build your business. School will seem to get in the way but being able to do both is important. It will speak leaps and bounds more then just quitting school and doing real estate alone. I'm not saying you cant quit and be successful, but the merits of saying/showing you committed your time and financials to furthering your education says a lot about your character that certain people in the world value tremendously.
