Welcome to this fully renovated legal 2-family home — an ideal opportunity for owner-occupants, investors, multigenerational living or anyone looking for plenty of room to spread out. This property features two thoughtfully updated units. The first-floor apartment offers 2 bedrooms, a brand-new full bathroom, and a modern kitchen with new appliances. Upstairs, the second unit includes 3 additional bedrooms, another new bathroom, a fully renovated kitchen, and a bright, open living room. Both units have their own new HVAC systems, hot water tanks, and are separately metered for natural gas and electric — with two brand-new 200 AMP electrical panels. The home is packed with upgrades from top to bottom: a new roof, gutters, windows, and exterior doors. A brand-new septic system, new plumbing, and all-new electrical wiring ensure peace of mind for years to come. The basement is unfinished but offers excellent potential, with two egress windows, outside access, insulation, electrical rough-in, and spray foam insulation already in place. Outside, the property continues to impress. The in-ground sprinkler system keeps everything green and low maintenance. Bonus alert: there's a full walk-up attic — a spacious third level just waiting to be finished into additional living space, a home office, studio, or whatever your needs may be. Whether you're looking for a turnkey investment property or a home with income potential, this one checks all the boxes.
