As a former travel therapist and resident of Denver, I would encourage you to contact hiring managers at hospitals, home health agencies, and skilled nursing facilities.

they will call doctors and therapists. 

I was thinking it's the commom practice to charge termination fee (for my time and energe to search for new tenant).

I had my 10,000 hours in my previous career as a Physical Therapist. 

I have already posted the rooms on a local therapist facebook group but still haven't had any luck filling the spaces. 

A new prospective tenant, a therapist, would have visiting clients, which means increased liability.Is there any benefit to upgrading from a regular residential policy to a commercial policy for the whole building, or is simply requiring the new tenant to list us (the property owners) as additional insureds on their liability policy sufficient, making sure they carry at least $1 million in coverage?

In addition to travel nurses (only one small sector, but the best known) I've had physical therapists, doctors, physician's assistants, phlebotomists and respiratory therapists.

The feeders to the panel will still be live, but at least the breakers will be de-energized.

Looking to re-energize my investing and pick up some helpful advice.

That needs to be a mental health professional such as a doctor or licensed therapist that is seeing the person they prescribe it for.
