22 Years Old with $22,000 CASH!!! What to do!?

[Jonathan Jaime Velarde]

Good Evening Friends!

I am selling my truck and will have just over $22,000 cash to invest freely. I have no debt and excellent credit. I am stationed in Washington D.C. and will be transitioning out of the military in about 9 months so I don't necessarily want to buy here and then have to move across the country and attempt to manage while in California. 

The area I will be moving to is in Ventura County where the price of real estate is pretty expensive! My college education will be covered by the Post 9/11 GI BILL and I will be living at home for free during the remainder of my college years. I estimate that by the time I leave the Marine Corps I will have about $42,000 cash and roughly $16,000 in my Roth IRA (no debt).

I am looking for some advice from people who were once in my shoes are are dealing with the same questions currently. 

Thanks!
