This small but mighty two-story colonial is centrally located in the heart of Monmouth Junction (South Brunswick), directly across the street from the Monmouth Junction Post Office and around the corner from the Monmouth Junction Kitchen (Diner). The first floor features a kitchen, a full bath, a dining room, and a living room, while the second floor contains three bedrooms. Additionally, the house includes a full unfinished basement that provides space for utilities and extra workspace. The backyard features a storage shed as well as space to enjoy the great outdoors. Although the property needs some TLC, it has great bones, appears to be in sound condition, and is being sold strictly as-is. This is a gem of an opportunity for any first time homebuyer, investor, or handy person.

Village of Monmouth Junction, located between Kingston and Dayton, is a rail-adjacent and suburban Monmouth Junction neighborhood with a wooded edge and a low-rise streetscape. The neighborhood’s character concentrates around the Ridge Road and Deans Lane corridor, where small plazas, local eateries, and everyday services set a steady, commuter-town rhythm. The historic Monmouth Junction station site and the Dinky line legacy still shape the area’s geography and sense of place. Housing reads as a mix of mid-century splits, townhouse communities, and newer infill along curving residential streets. Side roads thread toward preserved green space and trail corridors tied to the D&R Canal network. Rutgers Gardens and nearby campus energy add a cultural counterpoint to the quiet blocks.
