Say if your paying electricity for your home, a guest house, a in-law house and a store on your property, how much would it cost? Can you put it all on one bill?
Yes you can put it on one bill but that will probably cost you just to do that. As for how much it will cost depends on where you live and what state you live in. I would actually probably just ask the neighbors and find out how many people actually live in that house and factor that in the equation.
