I have a tenant that filed bankruptcy a few years ago due to a divorce and major medical issues. 

That is pretty rare as people like that simply don't go anywhere until they get a medication regimen that works.

These could include any legal, licensing, office, and even medical expenses.

I like this strategy, because if all of their info checks out then you're most likely getting a quality tenant in place, especially with medical professionals that require strict background checks. 

Alternatively, consider furnished rentals, particularly for students in medical programs or those undergoing residencies.

As a Landlord who has No Smoking policy, I understand that smoking weed is apart of that but what about Medical Marijuana?

Help the claimant with an immediate need - finding medical care, etc.

I now require any animals brought onto the property for any length of time, even service and emotional support animals, to be registered with petscreening.com or otherwise verified through a third party, and if tenants or their guests are not happy with that, they can send the documentation directly to me (vaccination records for the animal and a doctor's note with medical license and clinician contact information be sent to me).

See medical/nutrional/fitness professionals, do a biometric screen, and log everything in MyFitnessPal.
