Minimum Amt. of Renter Insurance You Require for your Tenant

Hi Bigger Pocket Friends! 

As a landlord, what is the minimum amount/requirement that your tenant must obtain as part of their policy and coverage? 

There are different nuances of a renter's insurance policy and coverage. So what do you tell your tenant so they can work with their insurance agent and get a policy that satisfies your renters insurance requirement as landlord? 

I am asking my prospective tenant to get renter's insurance, but I am not sure what to communicate to them so they can get the right policy and coverage. 

Thank you all in advance!
