I just came across your post. The very first thing I'd do is REJOICE that I am that smart at age 22 to start investing in real estate. I can't emphasize enough how wise this is. Congrats to you!! You are decades ahead of most! Time will be your friend, as well as your frugal spending habits.
After rejoicing, I would learn everything I could so that I could start forming my real estate goals, strategy and plan. The Bigger Pockets Beginner's Guide to RE is a great resource to help you start doing that. Also on this site is a recommended book list. I have "read" many real estate audiobooks while on my commute. You said that you are a big reader, so soak it up! I personally started to notice repetition as I moved to the next book or podcast, and then I knew I was gaining a solid foundation of understanding. (I am getting ready to select my first investment property in the next few months.)
There are many ways to invest or make money in real estate. Having a goal and creating a plan to reach that goal is going to help you decide what to do with your money. Also, real estate is local, so you have to consider your market and whether you plan to invest there or elsewhere. These are some reasons we can't all tell you more specifically what we would do in your situation.
Good luck and congratulations!!
