I'm underwriting a building now that's in a salt air city, a block from the beach. 

I’m active duty Air Force…I look forward to hearing more about your journey.I wish you all the best.

The fresh air, exercise, and mental clarity are all major benefits.

Also, there is no visible mold and no mold smell in the basement (there is a little on the caulking beneath a single pane picture window upstairs which I'll deal with).That didn't sit too well with the tenants as they have been looking online and finding information about how dangerous it might be, and it didn't help that the first report that I had done the inspector attached a boilerplate message recommending a full HVAC cleaning (ducting is 1 year old) HEPA vacuum, air scrubbers, double washing everything in the unit with bleach, etc. so now the tenants are being fairly combative and insisting that more needs to be done.

They heard nothing I said.. they just wanted me to move the trellis so they can have air in their window and the dog can look at the wildlife in MY yard.

I’m active duty Air Force as well.

If you didn't specify, then the person you were talking to might have thought you were just talking about a short term rental / Air B&B.

It is pretty well known that the more boxes you can check off on your air bnb listing far as what amenities and features you provide the better.

Also worth taking a look at cities and metros in person, although the flight and hotel/air bnb can add up, you can generally write those costs off, and in general getting on the ground and feeling the energy of a city or market can tell you a lot about the intangibles there.  

You can make minor adjustments based on the type of appliances (dishwasher, clothes washer and dryer, air conditioning, etc.) and the size of the rental.
