On FHA, you can do what's called a "non-occupying co-borrower", meaning the co-borrower is not occupying the property as their primary residence. 

Either way, we don't want unhappy residents in our houses.

If a family friend lends me $30,000, for example, to buy a foreclosure, where does the lien/title reside?

Found a single family residence for 105 list price, arv 230 with 40k reno, i figured i would go in 90k max offer but submitted a 70k offer, the bank rejected it lol.

I've used the house flipping calculator here on bigger pockets, although I'm thinking the nubmers would change a little big given the fact that it would be my primary residence for a minimun of 2 years.

Was you first property a conventional loan as a primary residence? 

Or you may be referring to local incentives (usually state or city based grants = free money) for communities that need people to buy primary residence in order to stabilize the town.

I currently reside in North Atlanta (Dunwoody area) and looking to make my first Real Estate Purchase.

Yes, you still own the homes despite having RTO residents and you may end up with a fair number of vacant homes due to default.  

My dilemma is whether I use my VA loan for the multi family which will turn into an investment property after I change duty stations in two years or save that VA loan for my personal residence once I establish more permanent roots upon competition of my service.
