Insurance question for MTR

Hi!

I've been renting out my 3/3 end unit townhouse for the past three months through Furnished Finder, to a great tenant on a four month lease. It's cash flowing really well and I'm hoping to continue doing MTR. I'm wondering - what kind of insurance should I get for the house? Do I ask the tenants to have renter's insurance? 

Also, does anyone have experience in the Nashville market for MTR's? This one tenant has been great but we've only had one. Hoping we don't have too many vacancies. I did list it on Zillow for LTR and have received some interest, a lot of it from STR arbitrage companies. That seems a little chaotic and risky to me. The property is 5 minutes south of the airport in a quiet, dead end neighborhood.
