I wouldn't be surprised if a veteran in the game is impressed with you being so interested at your age takes you under their wing as a mentee, or even some sort of unpaid intern type gig.As for investing your current $$, I'd say open a high yield savings account (Ally, Citi, or Marcus by Goldman Sachs) and start stuffing money away from your part time job or side hustle, and save towards a down payment on your first investment property. 

The old adage "location, location, location" rings true in this game.
