Sullivan County Land for Sale in New Hampshire

Newest

Sullivan County holds the western shore of Lake Sunapee along with Newport, Claremont, Grantham, and the towns running up toward the Connecticut River. Land here generally prices below the Merrimack County side of the lake, and parcels tend to be larger. The county carries a substantial amount of forest land, much of it enrolled in current use, alongside a smaller number of cleared lots with existing frontage and utilities already brought to the road. Browse lots over 20 acres or explore Grantham homes with a basement.

Frequently Asked Questions

How does pricing compare across the lake?
Sullivan County land generally prices below comparable parcels on the Merrimack County side, and acreage tends to come in larger pieces.
What is current use?
A New Hampshire tax programme that lowers the assessment on undeveloped land. Changing the use triggers a land use change tax, so check the status early.
