your health insurance will thank you. 

I'm assuming he didn't have any issues with the place - the only way I could see him winning is if there was a health issue that wasn't addressed (broken water heater, bug infestation, etc.). 

If mold can be seen, if a musty odor is present, or if there is good reason to believe health problems are being caused by mold, a careful inspection of the home should be conducted.

You local health department will have your answer most likely as they license dogs and will know the certification required.

That said, I think a STR near the clinic could do really well.

Some munis want to license/permit short term vacation stays for health and safety.  

State and local health and safety codes that set maximum limits on the number of tenants (based purely on the size of the unit and number of bedrooms and bathrooms) may support your limit on number of occupants.

Took a totally free functional system and turned it into a paid system full of bugs.I recently visited Zillow to do some market research and noticed on every rental listing they are showing this:In-person tours may not currently allow for safe social distancing or comply with public health orders.

Have things like POD (payable on death) for any separate bank accounts and of course, have our Wills, Health Directives, ect written out.We fail to see how legal marriage would benefit us.

However; each tenant is still responsible for all of their own medications, and assisted by home health aides, if required (which the tenant sets up and pays for themselves)  I've seen in some of the larger retirement homes that many of the tenants aren't there for medical reasons, but because their spouse died, and they didn't want to live in their homes alone with all of the upkeep etc., but they're still mobile and able to take care of their needs.
