The Overall Wentworth By The Sea Community

Wentworth By The Sea is a unique residential community that includes 107 single-family and condominium homes nestled along the coast line of New Castle, New Hampshire at the mouth of the Piscataqua River to the Atlantic Ocean. Those interested in owning a home in this community should contact a local real estate agent for homes that are available. The community's approximately 100 acres are primarily dedicated to homes, but also include the Wentworth By The Sea Hotel and Spa Resort and the Wentworth Marina, as well as open space for recreational use. The nearly 20 acres of open space includes a pool, three tennis courts, and clubhouse facilities. The Marina has 170 boat slips, fuel dock, and launch services to the several moorings in Little Harbor. Across the harbor from the community is the Wentworth By The Sea Country Club consisting of an 18-hole historical golf course and practice areas, swimming pool and support facilities, four outdoor tennis courts, four indoor tennis courts and fitness center, and a club house with dining rooms, meeting rooms and lockers.

Neighborhoods in the Community

The WBTS Community consists of eight neighborhoods. Each neighborhood association is part of the overall WBTS Master Association, which has responsibility for managing and coordinating the shared rights and responsibilities between homeowners. Each homeowner is a member of the Master Association, as well as their neighborhood association. The Board of Directors of the Master Association, elected periodically by the homeowners, control and manage certain common lands and roads and utiities within WBTS for the benefit of all of the residents of the WBTS Community. Monthly assessments are collected from all homeowners to cover the expense of operation, maintenance, and repair of the Community Property and an annual Capital Reserve assessment is collected to provide for the expense of repairing or replacing significant capital items benefiting the community, e.g., road pavement. Individual homeowners are billed by the town of New Castle for sewer usage and the city of Portsmouth for water usage.
