The tax rate is simply the product of your town budget (and other state assessments) divided into the total assessed real estate value for the town. If the rate changed, it could be that the value of the tax base declined (possible for non waterfront property given current real estate values
) or the total budget went up. Town meeting approves the budget so if that went up, the voters did it. That's how town government works. The state assessment is another matter.
My point is only that the tax rate is simply the way the town's total tax burden is spread around. Whether it goes up or down does necessarily mean anything. The better question is how much did Wolfboro's total tax burden go up and why.
Then it's a question of how much the value of your home changed RELATIVE to all other properties in town.
Those two figures are really what drive your taxes. Not the rate per se.
Just my 2cents.
