The US isn't perfect, but we aren't on the verge of a coup or imprisoning journalist wholesale so that lends an air of perceived stability.

Any ideas on how I could rent out the space in the backyard if not for a party or air bnb?

This is poor and toxic behavior imo  the fact is though, that S8 are just people no different than anyone else, some are wasting air while most are outstanding humans.

This is inclusive of disposal fees, permits to remove, air studies, etc etc. 

You can have a plumber do an air pressure test.You could also budget for plumbing repairs and work that into your contract price.Or you could just wing it!

I love my job in the Air Force and plan to continue serving my country, but I would like to own my own real estate investment business with a construction/home improvement branch.

One trend is to buy a single family and do air bnb for each bedroom.

Interestingly, it wasn't until I decided I was ready to transition away from my current business that I popped up for air long enough to realize we had built one of the largest, most branded and visible, and highest grossing detailing businesses in the area.

I popped up for a surprise visit and the lawn was severely overgrown and air filters looked like they hadn't been changed in months, so I fired him.  

You're saying your wife will be active duty Air Force in 2020.
