218 Main Street, Alton, NH 03809

Property Description

Rare Alton, NH investment opportunity offering up to FOUR potential rental income streams on one property. This unique property combines a recently updated 3-bedroom, 2-bath home with a large two-story outbuilding offering additional commercial and residential rental potential. The main home can serve as an owner-occupied residence or a standalone rental, while the outbuilding opens the door to multiple income-producing possibilities. The first floor is a spacious, wide-open garage ideal for a workshop, contractor space, auto detailing, woodworking, 3D printing, equipment storage, or other business uses. Upstairs, the opportunity gets even more interesting: an approved septic design is in place for the buildout of residential space, with the existing layout offering the potential for one larger apartment or two smaller units, each with its own entry and plumbing. Rent the home, rent the garage, create one apartment- or maximize the property with all four potential income streams. Whether you're looking for an owner-occupied investment, a multi-unit rental opportunity, or a flexible property with room to build value, this is a rare setup in a convenient Alton location.
