Trying to get into the game

[Max Bierman]

Howdy! I'm looking to get into real estate (part time, to start) and I figured this was the place to go. 
Looking for a little advice as to my next steps. So I bought my first house last October. Locked in at 3.2% VA loan (thanks Brexit). Currently my mortgage and HOA are around $1,600/month. I have a roommate who pays me $750 cash/month. What I would like to do is acquire another property sometime this year but I don't have any cash to put down at the moment. What is my best option? I am currently prioritizing saving cash as a back up, but could I refinance my VA to a conventional then do another VA loan for the next property? Any advice is welcome!
