Description

Excellent opportunity for investors or owner-occupants with this well-maintained up-and-down duplex offering strong income potential and flexible living arrangements. Live in one unit while generating rental income from the other, or maximize your investment by renting both units. The main floor unit is currently vacant and features a spacious layout with 1 bedroom and the potential for a second bedroom in the lower level. This unit offers a bright eat-in kitchen, generous living and dining/family room areas, ample storage space, and an updated bathroom. The vacant status provides immediate occupancy for an owner-user or the opportunity to secure market rent. The upper unit features 2 bedrooms, a spacious living room, dedicated laundry area, and a private south-facing balcony that enjoys excellent natural light throughout the day. This unit is currently rented at $995/month, providing immediate income from day one. Several major updates have already been completed, helping to reduce future capital expenses and providing peace of mind for the next owner. Improvements include a new roof (2023), gas furnace (2018), hot water tanks (2015), renovated main floor bathroom (2014), and weeping tile with sump pump installation in the basement (2009). The property offers manageable operating costs with 2025 expenses including approximately $816 for water, $1,044 for hydro servicing the main floor, common areas and upper unit common services, and approximately $1,700 annually for Enbridge natural gas heating serving both units. Whether you're looking to offset your mortgage through rental income, expand your investment portfolio, or secure a property with future upside, this duplex offers flexibility, functionality, and long-term value. With one unit already generating income and the other available for immediate occupancy or rental, this is an excellent opportunity in today's market. Some photos virtually staged.
