I have propane, too (in southern, NH) and I have a $1,500 credit with my propane company and, this year, we're paying less than $150./mo (for an 11mo plan) to heat my house that's over 2,400sq ft.
Over the last few years, we've never used as much as we've paid for and the credit keeps racking up and the monthly payments keep going down when we renew the contract.
I also have to agree about PSNH! Get a generator! My lights will just go out, randomly, for hours at a time. No reason given. Before I got the generator, I stopped re-setting my clocks. They all just blinked because I knew it was useless to re-set them when I'd lose the lights again the next day.
If you work in MA, you'll have to pay taxes there. Sometimes, even if you work in NH, you'd have to pay MA taxes (my friend's DH is a carpenter and works out of the Salem, NH shop of the MA union and has to pay MA taxes even though he neither lives nor works in MA).
My taxes are insane. They weren't bad before and then, WHAM, last year, they went up about $1,000/yr. This slammed my mortgage escrow and my mortgage payment went up about $250./mo (this was after I sent them over $900. to "re-pay" the escrow the deficit).
I did the commute to Boston for about 5yrs. I didn't mind it for 3yrs and then it got to be miserable. At least once a week, something would happen (accident, snowstorm, rain, a cloud passing overhead, who knows) and it would take me upwards to 3hrs to get home. I used to leave my house at 4am, so I could be at work by 5:30am, and leave around 3pm. There was still an enormous amount of traffic heading home (everyone else had the same idea). I tried a variety of public transportation options and tried 93, 95, and 3. No matter what I did, I always had at least 1 day a week where one trip was a nightmare.
With the propane....I do a budget/lock-in contract. I pay the same amount every month for 11mo and my rate can't go over a certain price per gallon, but, if the price is less, I pay that. Since I have the credit, my payments keep going down. I have Energy North Propane.
Stay away from FairPoint, if you can, too. They double-billed me so much I won't have to pay them for the rest of the year with the refund they owe me.
Happy house hunting!
