Located in the Miller Park neighborhood of Seattle, known for exceptional walking and biking scores, this property consists of a triplex + detached accessory dwelling unit (DADU). These well-built buildings were constructed in 2024. Units are equipped with full appliance packages that include refrigerator, oven, over range microwave, dishwasher, and full-size washer and dryer. Other amenities include wall mounted mini-splits that provide heating and cooling. Uniquely, the buildings have solar panels on the roof. All units in the triplex were newly leased in early 2026, and the DADU remains vacant for the possibility of an owner occupant. Two units in the triplex are designated Mandatory Housing Affordability units (MHA). These units have restricted rent based on MHA schedules and are also restricted to tenants that qualify under the program. The designation is permanent for these two units. The other two units can be rented at market rates or occupied by a new owner. Expenses are mostly estimated.
