Yes getting a report from the plumber would be ideal; however, I believe your issue will be no one knew that an open window would cause the pipes to explode. had you given them a notification the first time when it happened then you could say "Hey I explained to you this would happen" or have it written in the lease agreement.

Upon notification of death, the brokerage can handle the transfer on death and have the accounts created and assets transferred in less than few days. 

Many do not if the property is going to be used as a business (a rental etc).
