It is not because this beautiful antique rambling cape is privately nestled on the island community of New Castle. And it is not because the town offers so many amenities and is so well managed that the property tax rate is one of the lowest in New Hampshire. It is not even because the island elementary school was chosen as the best elementary school in New Hampshire for 2018. The reason that this is an unprecedented opportunity is because this 3500 +/- square feet of custom woodwork and cabinetry, 9 room home is nearly hidden on just under three quarters of an acre on the Portsmouth end of the always popular and historic town of New Castle a/k/a “The Great Island” is available for the first time in 40 years. This is a must see property for those with an appreciation for authentic wide plank floors, hand hewn beams, and hand planed would panels completed by famous local craftsmen and incorporated into a classic home loaded with current amenities and features. There is an existing legal accessory apartment. Perfect for relatives or long term guests. Plenty of room to add on. Appointment only. Sign at end of driveway.
