NEW CASTLE

- New Hampshire -

New Castle's Location

New Castle, originally known as "Great Island" (and still referred to by many locals by that name), is the smallest and easternmost town in New Hampshire. It's not very accessible from major roads and residents seem to be just fine with that. The island is nestled at the mouth of the Piscataqua River where it meets the Atlantic Ocean. New Castle is home to some of the most expensive real estate (and lowest property taxes) along the Seacoast. Residents have quick access to Portsmouth which is only a few miles up the Piscataqua River. 

New Castle is also home to one of the most historic grand hotels of the late 1800s - Wentworth by the Sea. The hotel closed in 1982 and was almost demolished before it was saved by an investor group and reopened in 2003. Today, Wentworth by the Sea is a thriving resort with a full-service Marina. It has also become a popular location for weddings due to its sweeping coastal views, first class amenities and close proximity to Portsmouth. 

On an island as small as New Castle, housing inventory is low and turnover even lower. In 2017 there were only 18 homes sold. The average price range for those homes that were sold is an eye catcher as well, just north of $1.5M.
