In the US, you also have medical and I have no idea how much that is (I'm in Canada).

I have a tenant who terminated their lease early in writing due to medical reasons.

Both my husband and I work in the medical field & traveled for a few years, so we are interested in hosting traveling nurses in Nashville. 

Most insurance companies will throw $500-$2,000 to someone for medical if they trip and fall on something, as long as it isn't seen as a hazard that should be fixed.

We are 5-10 miles from a handful of major medical centers and facilities. 

I understand this is the way syndication works with multifamily properties because the operations are generally only a few people, however, in senior living, the operations are much larger and more litigious because we are providing 24-hour care, medication management, meals, transportation, activities, etc. 

If caught, best case scenario is you'd get a cease and desist letter from the state regulator and probably fined. 0% chance this is worth it.

The problem is their only source of income is the husband's medical disability check.

After I posted this, I had a medical situation that we were dealing with to top it all off. 

Are you kidding me, your entire investment is based on using the property for short-term rental - any complaints by neighbors and you have to cease.
