What do I need to do to ensure tenants buy Renter's Insurance?

Question: I am a landlord and am leasing up right now - how (did) you manage to have yourself and your tenant covered under the renters insurance policy that you opened for your tenant?

Why is having tenants buy their own Tenant Insurance policy important?

So - you've found the perfect tenant after vetting their background, checking their credit, and they have the cash and matching move in time. Getting them to sign the lease and move in is it - and your headaches are over, right?
