Folsom- Salter House Rare opportunity to own a piece of Portsmouth History. The Folsom- Salter House Mansion is currently a beautifully restored 15 office suite building within walking distance to all that downtown Portsmouth has to offer! This historic building is being sold as a package with 105 Court Street, a two unit duplex with rare 10 off street parking spaces. This is a great opportunity for a business looking to move downtown but can't find large enough space, or possible conversion. The Folsom - Salter house was built in 1808, with it's greatest claim to fame that the 5th President of the United States, James Monroe, stayed there during his visit to Portsmouth July 12-15, 1817.
