Best of luck with your purchase!
You should be paying market rate for the oil, just like you are paying market rate for the home. I would suspect that if the seller paid $1.00 for the oil he wold ask $2.19 the going rate. Stick to your guns on this, remember you are the only one at the closing table with money. Best Robert
It is usually the current rate at the time of the closing. It is customary for the oil company to visit the home the day of or a few days within the closing and conduct a final reading of the remaining gallons. Following the reading, there is a bill issued with the current gallons at the current rate that is brought to closing. Best of luck to you!
