Next-to-nothing electric utilities should be a great selling point.

So what we have is two people paying rent and utilities in a home without a lease, contract, or any proof of an agreement. 

Your level of customer service has made her happy so far!

What software do you utilize to find out all of this info?

@Phillip Tamez, I determine the mid-range rent utilizing comparable rentals in the area.  

If my offer is accepted we will do the rehab and market the house for rent starting at $750, no smoking, no pets( if renter insist on having a dog I will add $25 on top of base rent and a non-refundable pet deposit of $250)tenant pays all utilities and does yard maintenance.So, as of now I’m projected to net at $266.

Will that include utils?

So during the option period and i am collecting rents from both units, I'm pretty much a landlord because utilities will have to stay in my name because the duplex has one electrical service and heating boiler.  

Know who to call check on utilities sewer etc. 

Randy I'd say it's some poor customer service on their part by not keeping you in the loop however I don't see a negligence case here.1.
