I truly think that the choice is really a personal preference. I wince at the thought of telling someone not to go to college (I am a mother), but at the same time, I don't believe that college is necessary to be successful in life.
Real Estate is an EXCELLENT career, and there are many spokes of it (Residential, commercial, finance, property management, syndication, etc). Having a degree in something that compliments your area of expertise only helps you, and can sometimes validate you to others seeking your advice, however, it isn't required.
Getting in as an investor can be as simple as buying your first home for you, using a first time home buyer program for down payment and/or closing cost assistance. Then living in the property for the minimum required amount of time. Get a roommate or two, charge them rent, and put that away for your next deal. Then do it all over again. Rent out your 1st property, and buy the 2nd one for you. Repeat those steps until you have either the portfolio that you want, or the capital and experience to move forward with an investor purchase.
I would recommend 2 things to you.
First, read RICH DAD, POOR DAD by Robert Kiyosaki. He actually has a whole series that will really speak to you as I think you will be able to relate to his story of having a family who can't see your vision.
Second, if you really want to get into Real Estate, I would recommend speaking to someone at Keller Williams. Now, I am bias a little bit as I have been with them here in AZ for over 20 years, and I am a vest partner (so full disclosure). However, when it comes to training agents to think like MILLIONAIRES, there is no one better, IMO, to train, get up to speed, nurture, and grow to the next level.
I can set you up with a team leader in your area so that you can do some information gathering if you'd like. Just PM me. I am happy to set it up for you. At least it will give you some options to consider.
Best of luck to you!
