Make sure to check property tax rates!

Derry has a good school system and a great high school (Pinkerton Academy).

Getting to BOS is easy enough if you stay near the 93 or 3 corridor.

I would try to stay on the west side of the river if I worked in Merrimack. Getting from Derry/Londonderry to Merrimack is better now that they built another bridge but it still takes about 20 minutes and Rte 3 sucks at rush hour.
