I am originally from Ohio where I joined the US Navy, then got stationed in Virginia.

For some, the distance to the nearest fire station is also a big thing. 

I looked into some opportunities closer to Penn Station but demand on Airbnb seems to be soft and prices pretty low.

Call the local police station and they will do a free walkin assessment to better tell you how to secure the property. 

I have a few LTRs right now but will also be looking to house-hack once I get back to the US and PCS to my next duty station.

The area is not the best, but it is walking distance to a train station to the city.  

I will move this year and rent out my current home.my questing is should i use some of my 100k to pay 25%+ down or use a 0% VA lone to buy a 3-4 plex at my next duty station? 

The only problem being stationed there is because of my status I can't buy and own property as military personnel.

FYI: I'm currently helping multiple active duty service men and women stationed in and around San Diego identify properties they can househack, and/or save some of their bah, while they create equity.

I've been stationed here for 10 years and REI'ng the last five.
