Some states require an established relationship with the health professional, not just one evaluation, but many others, it’s just a letter from a professional if disability and/or reason for animal is not readily apparent.

I priced it only about 14% higher than the long term rental which matches traveling health professionals' budget on Furnished Finder.So I'm leaning toward longer term rental because even if I secure midterm tenant, that 14% more isn't really worth the potential vacancy. 

This helps you, as the buyer, understand the health of the asset.Where in the post does it say anything about what a seller makes?

@Lia Veit  Maybe Try joint venture for the first few flips with investors on this board whom you can meet at meetups and then you can have better idea of how REI works

Health and safety2.

You can always request Medical Documentation: Request documentation of her medical situation and a letter from her doctor to make sure her condition will improve and ask if she is up for taking care of the property while she is recovering.Check Her References: Contact previous landlords for references to get a sense of her reliability as a tenant.Lease Terms: You can always start with a 6 month or a 1-year lease option if you have a good idea of her overall health condition.  

Tenant risk is lease term remaining, sales/billings from the location, overall financial health of the tenant (i.e. solo practitioner with this one center as their sole source of income and declining billings, will not likely keep the property well maintained, and when they move out, you will have work to do), need for this use and/or competitive urgent cares in area, etc. 

My property manager is getting old and is having health issues.

JV (joint venture) with someone to show you the ropes and then split the earnings 50/50.  

However, landlords are investing heavily in upgrading office spaces to meet modern tenant demands, such as flexible work setups and health-conscious designs.
