I had a family emergency with unexpected medical costs and had to cancel a reservation.

This allowed us to not only tap into the tourism market but also gave us access to traveling medical professionals and students as well that would provide long term tenants if we were prevented from continuing with the STR model.Although we still have a long ways to go to meet our goals, we are excited for the foundations we had setup for this property to this point.

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.
