Utility records in a triplex?

[Steve Volk]

I'm looking at buying a foreclosed triplex that uses a natural gas hot water boiler to heat the  building. I was wondering if it's possible to call the gas provider and get a statement of the prior few years gas usage so I can estimate the bills that I would have to pay if I buy it. Has anyone else done this with the utility companies on an investment property? Will the utility companies release this information to someone who doesn't yet own the property?

Thanks!
