Second, skin in the game.

I'm admittedly fairly risk-adverse in the first place, and between our ages and personal circumstances, what to do next is a challenge.

Troop levels at the base change on a fairly regular basis. 

@Brent Coombs Which is completely fair; to each their own.

As long as you do that (allow them the ability to have them installed, and don't "prohibit" the modification) then you have made a reasonable accommodation and are ok as far as the ADA/fair housing goes.Obviously you really should read the appropriate portion of the act yourself, and if you have any doubts or questions seek appropriate legal counsel.

Within a fairly concentrated area I found about 15 such properties, took some pictures and recorded the addresses, but I'm not really sure what to do next.  

Your offers have to be more fair, and unfair offers for yourself can lead to complaints to the real estate commission.Really the idea of building up ill will and the threat of complaints to the real estate commission are going to follow most parts of the transaction if you are licensed.

My houses to the south in Hazel Park go fairly fast.  

I just want everything to be fair for my partner.  

He is very good and fair on pricing.
