Do You Require Tenants To Carry Renter's Insurance? Why?

[John White]

Good Evening...

I've seen a lot of leases where the property owner requires the tenant to show proof of Renter's Insurance.  Is this something that you do?  Why?  I guess the real question is what impact does it have on me as a Landlord, if something were to happen, and a tenant opted not to have insurance.  Obviously, we all understand that our investment properties are only insured for the dwelling (s), and not contents. I just want to know if this is something that I absolutely should require, and if so...why?
