If the buyer waived inspections, who is wanting them turned back on?
Here, the utility companies wait out the seller of record's desire to turn utilities on somewhere else - and then they first require payment for the amount in arrears.
(They know how to get their money!)
The mortgagee does not turn on utilities here because they function as a machine. Here, if the buyer wants a home inspection, or they're getting a conventional loan & their lender wants to do an appraisal, the buyer is welcome to turn on utilities for the purpose of inspections & appraisal. No,they are not required to pay up any past due amounts, but yes, they are required to pay any deposits charged and for the utilities consumed for however long they leave the account active.
