I bought my first property when I was stationed in Abilene about 3 years ago. I used my VA loan to purchase a 3 bed 2 bath and I lived in it for about 2 years until I PCS'd and I still have it as a rental. Not sure what you're current housing situation is but if you're living on base or renting I'd suggest using the VA loan and get a house now that would make a decent rental in the future. You could move out in a year and get another one. I didn't have much luck finding any multi-family when I was there but you could try finding a duplex, triplex, fourplex and move in one unit and rent the others out.
I'm definitely a fan of using the VA loan since it's no down payment and no PMI. If you're not a fan of actually owning a primary residence yet I'd probably try buying properties in Dallas/Houston/Austin, those markets are pretty good compared to Abilene. There's not much there besides the base in my opinion.
Hope you do well!
