Welcome to 337 3rd Street in Montebello, a cozy and modern home on a large expandable lot. This beautiful 3-bedroom, 2-bathroom house sits on an approximately 6,233 sq ft lot, zoned R3, offering a spacious backyard perfect for gatherings, parking, parties, and a play/grill area. This rare lot size and zoning allow future owners to potentially build two additional units, creating a triplex/ADU conversion (subject to city approval and plans) for extra rental income or family use, or keep it as a single-family home. Step inside into a completely reimagined home with an open floor plan, featuring all-new copper pipes, new plumbing, new kitchen cabinets and countertops, bathrooms remodels, double-pane windows, luxury LVP flooring, smart central AC and heating, dimmable LED recessed lighting in all rooms, upgraded 200A electrical panel with an EV car charger outlet, and much more. All appliances are newer LG models that seamlessly complement each other. The front yard offers a low-maintenance, zen-like atmosphere. Enter the backyard oasis to a two-car garage, a custom electric gate, a patio/grill area, a grassy space for pets and children, and one of the best orange tree to exist.
