Renting to an in home health care agency?

[Travis Daudelin]

Hi all! I got an unsual response to a listing of mine today:

Good morning, We are home health care agency, and we want to rent the house to care for disabled or elderly clients that are unable to care for themselves 4 -6 unrelated people. We are looking for 3 year lease if that is acceptable with you.

My initial reaction was to decline this offer. I am worried about having an intermediary taking control of my property and renting to tenants I haven't screened. I'm also concerned about the liability that I might be exposed to here by allowing what appears to be a business to operate out of my rental. But, perhaps this could be an opportunity in disguise? 

Has anyone experienced something like this with your own rentals?
