If you live in New Hampshire, but work in Massachusetts, you will still pay Massachusetts income tax. The property tax increase you will see in NH on a modest home will be more than offset by the savings in car insurance you will realize when you move from an urban Massachusetts area. You will be able to buy more and bigger in NH. Having said all that, I prefer the quality of life in New Hampshire. I have lived in both states and when it was time to raise a family, I came back to New Hampshire. I think you need to decide what kind of life you want, run the numbers and ultimately make a decision you can live with from your heart.
