The property consists of 19 one-bedroom / one-bathroom units, one one-bedroom + office / one-bathroom, and one three-bedroom / two-bathroom unit, totaling 14,975 rentable square feet across three stories of wood-frame construction. The property has been meticulously maintained during the current ownership and this is the first time the property has been marketed in 33 years. Current rents average below market across the portfolio, with one-bedroom units running approximately 6% below comparable market rents and the three-bedroom unit carrying meaningful additional upside. An investor operating the building at market rents and fully charging for parking and storage will bring the proforma cap rate to 7.0% with minimal capital needed. The building has been meticulously maintained throughout the current ownership. In 2016, elastomeric waterproof paint was applied to the rockcrete siding, the roof was replaced in 2019 along with the main water supply line, and in 2023/2024 the main sewer drain line and underground cast iron plumbing was replaced. Interbay 21 Apartments offers convenient access to major public transportation routes while being in close proximity to the employment centers, dining, retail, and neighborhood amenities of Queen Anne, Ballard, Interbay, and Magnolia. The building’s location on a quiet residential street provides a strong lifestyle appeal for its tenants and will be highly desirable for future tenants as well.
