18 years old. How can I get started in House Hacking?

[Hyuma Takamatsu]

Hello, my name is Hyuma Takamatsu, an 18 years old, college student at Rutgers University. Over the past few months, I have been researching a lot about real estate investing through books and podcasts. I gotta admit, I am very excited!

I have about $20,000 saved up over the years from working part-time minimum-wage jobs during high school and in college. I have also applied for a credit card last year and still working towards building my credit. I've come across a popular strategy, called house hacking through the books I've read and podcasts that I've listened and I am looking to do this myself in the next two-three years. What would you guys recommend I start doing now, so I can take this first step? Or, what are other ways I can get started? 

Any insight and advice will be appreciated! Thank you!
