OK, I am sure this will be one of those "no matter what someone says you will be set in your ways blogs" but I think we need to talk about this issue.
I have asked for utility bills for a home as a buyers agent maybe twice in my almost 7 years in Real Estate! I have agents that ask every time they show a home for utility bills. I even had one agent last week that asked for the bills before they even showed the home.
Full disclosure... we have several utility companies in our area (you can't choose) and some are higher than others with about 17% difference.
Utilities are based on usage people!!! Items to look for in lower utility bills would be good vinyl windows, a good HVAC system, brick or/and good insulation, modern energy star/green updates or upgrades, storm doors, age of the home, age of the HVAC system, and many other ways. Utilities may be high or low based on the life style of the owner. Does the owner home school? Does someone stay home during the day? Do they have people taking 2 showers a day (like my home)? How about the room temperature?
I would not ask for the water bills of a home? Should we ask for the grocery bills? How about the gas bill for the car?
