Single-level living and investment flexibility in University Place! This ranch-style duplex offers two spacious residences, each featuring 3 bedrooms, 2 bathrooms, approximately 1,578 sq ft and an attached 2-car garage. The generous layouts provide comfortable living space, while one-story design adds everyday convenience. Located within the University Place School District and situated off 67th, the property offers easy commuting options. Both residences are occupied by long-term tenants, with current rents below market presenting potential for future income growth. The seller has obtained approval for condominium conversion, creating an opportunity for separate ownership and individual resale upon completion of the conversion. Hold both residences as an investment, explore future owner-occupancy with rental income from the other side to help offset mortgage costs, or pursue individual ownership as your needs evolve. The layout also offers possibilities for multigenerational living: separate homes provide privacy and independence while keeping loved ones close. With a full 3-bedroom, 2-bath home and an attached garage on each side, each residence offers the space and functionality to stand on its own. Established tenancies, single-level floor plans and an approved path toward condominium ownership make this a versatile opportunity with several options for the next owner.

Perched on a sunny corner lot in sought-after North Beacon Hill, this classic 1905 legal duplex blends early-century character with modern comfort and territorial views, just minutes from downtown Seattle. A true standout, the property features two oversized units that live large and feel more like homes than apartments, each offering 3 bedrooms and 2 full baths. Both units were taken down to the studs and rebuilt with updated plumbing and electrical, individual gas forced-air furnaces, vinyl windows, and engineered hardwood floors. The kitchens shine with slab granite counters and stainless appliances, while the baths showcase porcelain tile and each unit enjoys its own utility room. Recent updates include a new roof (2024), fresh exterior paint (2025), and new interior paint in the downstairs unit, so the next owner can move in or lease up with confidence. Outside, enjoy a fully fenced yard and deck, four off-street parking spaces, and a detached one-car garage, a rare find this close to the city. Ideal for an owner-occupant seeking a savvy "house hack" or an investor looking to maximize rents, this property delivers flexibility and upside. Minutes to Beacon Hill Light Rail, I-5, and I-90. A rare opportunity to own a well-located duplex with space, style, and strong income potential. This is one you don't want to miss, and take advantage of up to 1% credit with preferred lender!

Six-unit apartment building in Seattle’s Wedgwood neighborhood, well managed with zero vacancies and zero delinquencies. All paperwork is in order, with pre-screened tenants, move-in reports, healthy security deposits and last month’s rent on file. Five of the six units have been renovated with new LVP, fresh paint and updated electrical packages, and three of those five also have remodeled kitchens and bathrooms. Major system updates include new electrical panels (2025), main sewer line replaced (2022), double-pane vinyl windows throughout (2025) and newer hot water tanks (2023). The heavy lifting is complete, allowing a new owner to take over operations with ease. The mix is two 1BD/1BA units (approx. 580 sf) and four 2BD/1BA units (approx. 800 sf) on a 7,841 sf lot. A large basement provides shared laundry and four storage units, and six off-street parking spaces offer additional income potential. The property is surrounded by new construction, reflecting continued investment in the area. Located in an established Northeast Seattle neighborhood near Green Lake, Seattle Children’s Hospital, the University of Washington, I-5 and the Roosevelt light rail station. Solid in-place rents produce a 5.74% cap rate today. By finishing renovations as units turn over and adding in-unit washers and dryers to the 2BD units, a new owner has a clear path to a 7.13% cap rate at market rents.
