About the Area

Living in Sullivan County

Sullivan County occupies the west-central part of New Hampshire along the Connecticut River. Claremont and Newport serve as the two main population centers, each with their own downtown character and community identity.

This is one of the more affordable regions in New Hampshire, making it attractive to first-time buyers and families looking for rural New England living without the price tag of the Lakes Region or Seacoast. The Upper Valley influence from nearby Hanover brings cultural amenities within reach.
