We signed the lease 3 years ago and renewed it every year. We are leaving and saw this about the oil tank. I was assuming since we paid for the full tank up front that we would be reimbursed for whatever oil is in the tank when we left. Sounds fair. Unfortunately our lease say we have to leave a full tank when we end tenancy. Our landlord recently email us saying she would reimburse us for the oil, so she forgot this was in the lease. Eventually she will dive into the lease and find this. Can she legally get a free tank of oil out of us?
