Tenant crashes carport. Help needed

[Shivaranjan V.]

I am buying a property in Texas from a seller. Seller is not giving security deposit citing that the tenant crashed into a car port and damaged it. She gave several notices to the tenant but tenant is not giving her money back. 

Seller has provided text messages from the tenant claiming the crash etc along with pics. 

As a buyer, What documentation should I get from the seller so that I won't have issues in the future when tenant moves out.

Thanks a lot in advance.
