Overall, the Seacoast area has proven to be a good investment. Through the past few years, the Seacoast has had a lower unemployment rate than the rest of the state, NH is consistenly rated one of the best places to live and the area does have so much to offer!
The real estate market has been steady and we are now seeing prices rise a bit. Even during the worst, this area didn't get hit as hard as most.
For property taxes, each town has it's own rate. Here's the link to the state governments list:
For an overview, Seacoast area towns range from $14.13 in Greenland to $25.92 in Exeter per $1000 of assessed value - so there is quite a range and property tax is an important factor to consider.
