Detroit Real Estate

How can I find the average electric and gas bill price for I house I am thinking about buying?

If it is a foreclosure it is not possible.  Usually the utility companies will only release this information to the people that live in the home.   Because the bank owns it now there is no utility history.  Without somebody living in the home it is not a realistic utility history.  And the old owners that were foreclosed on can not be easily found and most likely won't be cooperative.

But if it is a short sale or a regular sale have your real estate agent contact the seller's agent.  The sellers agent should be able to get the information for you.  It may take a few days to get the information but the listing agent should be able to get it to your agent.
