Here, figure about $80 for electricity, $95 for phone, DSL, satellite (no cable out here), $800 or so a year for heat (wood) ($66/mo for heat). Remote location makes gasoline a factor, since you have to drive to get to job, shopping, etc. About $85/mo in property taxes, though we have almost 10 acres. We eat pretty cheaply, because of all the stuff I put up with the canner, and the stuff that I freeze (2 fairly large chest freezers). When my wife shops, she buys meats and cheeses and some fresh vegetables, vegetable oil, pasta, rice, dry beans, flour for bread making, etc. It's hard to put a monthly price on all that, since some of those ingredients are fairly pricey, but the freezers help even out the swings. When there is a loss-leader sale on very good cuts of steak, she buys in bulk, repackages and freezes them. We could eat more cheaply, but food is important, and it is important (IMO) that you enjoy it.
If we had to buy all the salsas, chili relishes, pickles, etc that I put up every year, it would be very expensive and the quality just wouldn't be there.
Anyway, if you live in a rural area and can get somewhat self-sufficient, you can live fairly cheaply here. The closer to cities and creature-comforts, the more you'll pay for about everything. Apartment-dwellers with poor cooking skills had better have jobs that pay well, especially if they want to live in commuting distance of Portland or other popular place. Portland has become a prime "bedroom community" for Boston, and with the addition of the DownEaster runs on Amtrak years back, it's only getting more pricey.
