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 residence. The upper unit will be vacant by end of July 2025, while the lower unit is leased through April 2026, providing both immediate flexibility and reliable income. Don't miss this exceptional opportunity in the heart of the South End - just a short stroll to downtown Portsmouth, Prescott Park, and the city's vibrant waterfront scene.
