Did you ask about the bill in winter before signing the lease? It’s a standard question before signing a lease in Chicago. Are you otherwise ‘getting a deal’ on rent and now you know why it was a deal?
No, I am not getting a deal, I am paying quite a bit. I had some warning, when I signed up with the power company they required a deposit "based on location usage" which they sized at $350, so I knew ahead of time that was going to suck.
