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.
