Their pain point is that they need to be out of the place, quickly due to the health problem.

I like that they have built-in solar panels and batteries to power the home in the event of a Grid-down sitaution.My concern would be: will they be valued as manufactured homes are?

No unregistered vehicles and no vehicle repair on property is in the lease (although I wouldn't have a problem with emergency battery and tire situations, I prefer they don't change the oil on the property. 

Tenants that always call about everything are a pain, but tenants that never call are even worse for your bottom line.2) Replace smoke alarm batteries.

One example might be running a meth lab at your rental.In my experience judges come down harder on lease violations, particularly for health and safety reasons, than they are non-payment of rent.

Have a retirement and a health plan.  

In cases where I rent a room I just rely on checking they have a professional health care license and a job in the area but that is only because the roommate is my son.  

It can't be manufactured or mobile home and of course we'd have to do all the permits and if I'm coverting an existing building I'd have to have it engineered and permitted to meet code and environmental health requirements.
