This sounds like something a doctor or other independently wealthy person might do, to leave to his children as investments. 

I have a service animal request form that requires, among other basics:Written statement from doctor or qualified professional.Appropriate current State, county and/or city licenses.Evidence of current vaccinations from local veterinarian. 

Hi Jim -I can certainly also attest to the need for these types of properties, and also can attest to the fact that often times when people consider renting their property via Airbnb they consider that their location is not suitable because "it's not in a tourist area", overlooking the needs of people such as yourself, traveling doctors and nurses, researchers, etc.  

I am only 62 numerically but biologically my doctors tell me I am only 30. 

I use House Doctors but only after the engineer has prescribed the work.  

A lot of doctors and professionals live there.

It's a lot easier to become an engineer than say a doctor, or lawyer (with tuition these days, a whole lot cheaper too!). 

This will save you a lot, unless you go to the doctor every month and use a lot of Rx. 

You can probably build a brand spanking new building in the worst neighborhood of south Dallas, do you think you'll have a waiting list of lawyers and doctors waiting to rent there?

Doctors, nurses, relocators, techies, insurance temp housing will pay double to triple rents for those in many cities.
