    Overview

    Built in 1966, this well-maintained 9-unit apartment building offers a practical mix of 4 two-bedroom units, 4 one-bedroom units, and 1 studio. A standout is a ±1,200-SF top-floor penthouse unit featuring two bedrooms plus a den, 1.5 bathrooms, and sweeping Downtown and Space Needle views. The property has been thoughtfully upgraded with updated dual-pane windows, elevator service, and in-unit laundry and dishwashers in all units except the studio.

    Located in Seattle’s Capitol Hill rental market, the building benefits from strong transit access, with a Walker’s Paradise score of 95 and an easy route to Downtown and SLU. Within a 10-minute walk, there are 7 bus lines and a light rail station. Parking is also a differentiator here, with 11 total spaces including 9 off-street spaces and 2 garage spaces.

    This configuration supports multiple ownership strategies, including an owner-occupant scenario using the penthouse while operating the remaining units. The current marketing notes also point to potential income growth through rent adjustments to market levels, RUBS implementation, and monetizing parking. Condo documents are already in place, comprising 12 parcels (1 for the land, 2 for parking, and 9 individual unit parcels), which may provide flexibility for future sell-off planning and long-term disposition options.
