About this home

Welcome to 25 South Mill Street — a rare offering of newer construction (built in 2013) located on the waterfront in one of Portsmouth’s most sought-after neighborhoods. Currently set up as a 2 family home this would be a fairly straight forward conversion to a true single family property in a premier location. Each of the two units features 2 bedrooms, 1 full bath, and in-unit laundry, offering comfortable, modern living with a coastal flair. The upper unit enjoys elevated views and higher ceilings, maximizing light and enhancing the stunning water vistas. Outdoors, you'll find no shortage of parking with a deep, oversized garage (approx. 14' x 26') and a driveway that accommodates 6+ vehicles — an exceptional amenity for South End living. With flexible use options, this property is ideal for an owner-occupant looking to offset their costs with rental income, investors seeking a premium location asset, or those envisioning a condo conversion or conversion to a single-family
