How to Invest at 18 Years Old?

[Gursimran Singh]

Hello Everyone, 

I am 18 years old and I started investing 4 months ago. I invest in my Roth IRA monthly and I have started reading about real estate a lot as well. I transfer next year to a University and I was wondering how I can purchase a multifamily before I turn 20. I would love to purchase a quadplex or triplex near my University and live rent free with some roommates. Is this a viable option? Do you guys have any other tips I can use to start investing more into myself other than just an IRA?

P.S. I do only have some cash saved up but plan to be near $10000 by the time I transfer.
