You should probably do a little more homework on your tax situation. NH is technically a functioning state and has to pay for that function with some form of taxes. The result is that NH has the 4th highest real estate tax in the country. And if you earn your income outside of NH, in MA for example, as many NH folks do, you’re paying income tax in the state where it was earned, not NH.

I can’t tell you how many MA folks I know who moved to southern NH to “avoid taxes” but ended up still working in MA and ended up paying a much higher effective tax rate, kind of the worst of both worlds between real estate and income tax.
