You will need to build your CORE 4 when you get started which consists of having a great realtor, contractor, property manager, and attorney.

You need to amass a large portfolio for it to be passive (aka hiring someone to manage).If you want to be financially independent as fast as you can then you need to do a few things. 1) get as high of an income as possible (this usually takes schooling and/or experience, think high income profession - law, medicine,etc)2) live as frugally as possible (you will sacrifice a lot here, think of not going out with friends, live at home/save on rent, etc)3) invest as much as possible and I mean invest not yoloing on random hot tips (you are starting young, time will be on your side)If you do this consistently and remain highly disciplined, you will get there faster than most.
