Beginning to Save - Help!

[Liam Beard]

Hey guys,

So I recently finished playing college football which freed up a bunch of time for me to finally start working and saving. I was able to get a part time job making $12/hr and working about 34 hours a week while I finish up my last year/year and a half of school (which by then I'll be able to get a better job). I recently opened up an Ally Bank online savings account with 2.2% APR. Currently I am placing 70% of the money I am making from my part time job into this account. My goal is to reach FI by 32 (Currently 21). I plan on investing in a small multi-family and house hacking as my first investment. My question is should I continue to allocate most of my income into that savings account until I am able to make a move on a deal eventually or place the money I'm saving into Vanguard ETFs and start investing that way or go about this a completely different way? I know this is based on me and the goals I want to achieve but any advice would be appreciated. 

Thanks!

Liam
