530 Up Mountain Avenue This classic Up MTC colonial doesn't just bring the charm it comes with a built-in rental that helps offset your property taxes. The main house is 4 beds 2.1 baths, finished basement and all important wraparound porch that begs for wine nights and neighborly hellos. A proper foyer sets the tone with hardwood floors and shows off the great flow. The formal dining room brings the character with crown moldings and built-ins while the LR has a new gas fireplace and great space.The EIK has custom cabinetry, granite counters, subway tile, and SS appliances. A full bath rounds out the first floor. Upstairs, 4 beds, hardwood floors, second full bath and plenty of storage. The finished basement means hangout space, storage, laundry, and a powder room. Out back, you've got a great yard with patio, lawn, mature landscaping, and a detached 2-car garage. But PLOT TWIST. There's a bonus unit. Tucked away with its own private rear entrance, the adorable third-floor 1-bedroom apartment includes a kitchen, living room, full bath, and storage. Keep it as an income-producing rental or reintegrate it back into a single-family setup. The flexibility here is huge. Location-wise, it's kind of unbeatable: just moments from village of Up MTC, the train, town pool, Presby Iris Gardens, Mills Reservation, and easy access to Rt 3, the GSP, and NYC.
