I bought my first "investment" property as a primary home when I was stationed in El Paso, Texas. I did not purchase it with the intent of it becoming a rental any time soon. That being said, I never really analyzed it in that manner.
I've now used my VA loan several times to "house hack" in some pretty rough markets, more specifically California. Where I got lucky to hold for the minimum 12 months, put a little bit of money into it, and then move on.
The best thing I ever did was analyzed it to the best of my ability given the resources here at BP, a la the calculators and even using listing only services to ensure I get to keep the listing agents 3%, to ensure I get to leave with a much better check.
My next steps are looking like multi-families. Personally, I think the best thing you can do with a VA loan is to buy a 4 plex because if you play your numbers right (rental income vs. mortgage) you should be able to live rent-free at the very least and potentially cash flow right out of the gate. Live there for the minimum of 12 months, move on and rent out your prior unit to improve your cash flow. Just my .02, hope it helps.
