<prompt> Human: The lease for my current house, which I am renting with my college friends, started in January but we all moved in the 20th, which means weve all been living in the house for almost exactly a month. Yesterday our landlord emailed us saying we needed to pay a 170 electric bill. Before our lease started, he told us we should expect to pay 50, but this was never in writing. He also runs a dehumidifier and sump pump, which I am sure costs a lot of money no where in the lease does it say we have to run these appliances. Can anyone offer any advice as to what my roommates and I should do about this? Thank you, I will gladly answer any questions.EDIT: the house heating is oil except for the hot water, which is electric  <response>: Ask to see the bill.
