You have many options here.1) Terminate the lease: It clearly states that they must have renter's insurance and the lapse can result in a default2)Have them cover the damages with sufficient evidence that they caused it3) Claim it on your insurance for the property, likely they won't give a good payout unless a fire, flood, or some sort of wind damage.

There are more options for renters so it's putting pressure on rents btwn 10%- 20%.

You have to compare your expenses with each management style and find the option that works best for you.
