OR you could just call the utility company and give them authority and permission to keep it clear. 

Or, if the seller is highly motivated, they might not be able to reveal why they are motivated, unless their client gives them permission to.

Some agents have to pay a monthly desk fee whether they are productive or not.I don't have to get a broker's permission to do an odd transaction.

'it's better to ask forgiveness than permission'...

You will need to be able to talk to the bank about tax payments, insurance issues, payoffs etc in the future.You can technically, with their permission, take out and pay for an isurance policy that pays off the loan in the event they pass.

You MUST have the seller’s permission to obtain information from their creditors (so they can be paid off at closing).IF YOU DO NOT HAVE ENOUGH INFORMATION TO WRITE AN OFFER:In the event you do not feel comfortable writing an offer because you’re uncertain about rehab costs then schedule a follow-up appointment with the seller so you can return with the appropriate contractor.NOTE: It’s okay to let the seller know you need to get an expert opinion on a repair.

My rental agreement states I have permission and authority to do so.Any advice is appreciated.

as an agent you can contact the bank with the owners permission and many times you can get the sale postponed to get time to market and close the deal.. 

TREC permits a broker to be an intermediary and negotiate the contract with permission in writing from both parties.
