We bought a place in the fall, the previous owner said they owned the propane tank. It was noted on the property disclosure page of the contract. We have never used propane, or dealt with propane companies. We called the local co-op for a fill, and they claim the tank is one of their leased tanks. There are no company markings or tags on the tank. They said they would sure like us to set up an account. We have no proof of ownership, and that is where I think our problem will be. I dont want to get into a "lease" for some old propane tank I own. We wont be using much propane, it is a smaller tank, and we would only use it in the fall for the furnace and for the cooking stove. A fill would probably last a few years. Has anyone ever had to deal with this? I am about to tell them to come get "their" old tank off my property, just to see if it suddenly becomes mine.
