What this listing tells us
This exceptionally well-maintained 4-bedroom home sits on a beautiful, mature corner lot and offers incredible versatility. The main floor features a bright living room with a large picture window overlooking the trail, alongside a cozy family room with a gas fireplace and its own side entrance-offering distinct potential for a third unit. The former double garage has been professionally converted into a spacious primary bedroom, maximizing your main-level living space. Step downstairs to a fully self-contained 1-bedroom basement apartment complete with a separate rear entrance, full kitchen, 3-piece bath, independent laundry, and a generous living area with a second gas fireplace. Vacant and ready for immediate occupancy, this property is perfect for generating premium rental income, housing extended family, or transforming into a multi-unit income property. All of this is located just a short walk from town amenities!
