I am debating buying a house in Webberville Mich. and it has propane for heat. I am from a natural gas house and do not know how much the normal usage is or even how much it cost to heat a house for the winter. If anyone uses propane, can you educate me on your average cost and how much you use. I am thinking of buying a 3000 square foot house if that matters. This could be the deal breaker if it's to much. (PS. It's 4Cruizn listing. I seen his sign on the road)Thanks
