I noticed Bob's yard near Elroy while doing airport pickups and dropoffs. I just stopped in and talked. Pleasant surprise! A fairly well fitted out 40'x8' is "only" in the $60k range. That's with a 12000btu mini split, water heater, kitchen sink with (probably) induction cook top. Stud and drywall interior walls and ceiling. And a nice enough bath and more than nice enough shower. I have many items to discus with them but I can envision buying one or more.
Probably much more later.

Cook top is probably resistive rather than inductive. Not a difficult fix. They come standard with separate grey and black water outlets. I just cost me a few hundered dollars to have the waste water on it divided.
I envision a cluster of up to four with a single small septic tank. And, of course, the grey waters combined and routed to some place that needs irriation.
Use might be: a respite for me and/or others. Rental units for hunters, horseback riders and others.
Perhaps a single PowerWall for the cluster. Both for long term and short term power failures.
Need to think about rainwater collection and storage.
