Duplex with shared gas and owner pays

[Tom C]

I am looking at a duplex where tenants share one furnace and one hot water heater, thereby the owner pays for the gas. I am thinking about buying it, but I don't want to get stuck with the gas bill. So I am thinking about purchasing electric baseboard heaters for one of the apartments and disconnecting the heating ducts to that apartment. I will then need to get another hot water heater for that apartment and make that electric too. That way one tenant pays the gas bill. While the other has been completely converted over to electric.

Has anyone else ever been in this spot and if so how did you handle it?

Thanks
