babygill, I thinks it depends on the person lived in that 5 and 1/2. If the house not include heater, the electricity fee in winter will be at least 200$/month. Even in summer, 70$/month is necessary. So if three person lived there, 280$/month include all is reasonable.
Anyway, you can decide if you accept this price.
Actually, I saw the electricity bill, it is $180 for two months!!! So you think? Well, I just wanna warn people that they should be careful when renting from the second-landlord. At least, there is no need for me to pay the open account fee for both electricity and telephone.
