Short term rent request from Insurance Company

[Nazgul Tataeva]

I received an email asking only for 3 months lease maybe going month to month after and offered $500 more then I listed. She is saying she places home insurance claims. I want to sign the lease but little bit hesitant how the house will be taken care of the house. I already painted the walls and fix little things.

How would you proceed?

Any advice appreciated

Thank you in advance
