I'm 18 and have 12K saved what should I do?

[Jaben Jennings]

I am wanting to get into relstate and start building wealth very early on.  I already have about 12K saved.  House hacking definetly seems like the right way to go but I curently live with my parents and have very low monthly expesnses.  I am a little scared becasue House hacking would make my monthly expenses where most people are already use to paying a morgate.  I get the idea is for the renter to take care of most of the morgate but if take awhile to find my first renter... sounds tight.  I have a low paying job($40,000 anually).  I am just looking for any advice for my curent situation.

I have another question for a FHA loan is it correct that you need 2 years of consistent income history?

Again any advice I gratelly apricate!
