The offering consists of two separate structures on a single 4,800 square foot NR3 zoned parcel. A two bedroom house built in 1946 sits at the front of the property, and a standalone duplex built in 1988 sits behind it, containing two more two bedroom/one bathroom units. Total net rentable area is 2,340 square feet across the three units, with an additional 720 square feet of unfinished basement beneath the house. Each unit is a two bedroom, one bathroom layout with a dedicated storage locker and its own full size washer and dryer. Both duplex units are vacant and ready for occupancy. Both interiors have been freshly painted and have new vinyl plank flooring, new carpet, new window blinds, and the appliance package in the upper unit (unit B) is new. Hot water tanks were replaced in 2023 and 2024. The property also works for an owner user, who can occupy a duplex unit at closing. The house sits on 720 square feet of unfinished basement with a dedicated entry, good ceiling height, and a sewer line that runs down rather than out through a sidewall, which allows a bathroom to be added at the lower level without sacrificing space. A buyer can finish the basement as additional living area for the house or pursue the addition of a fourth unit. The parcel is zoned NR3, which allows four units on the site. A buyer is to research and confirm the viability of these options to its own satisfaction, including with the appropriate City of Seattle zoning and construction departments.

Evaluate Seattle three-Unit Properties

Seattle is a collection of distinct rental submarkets. A building in Ballard, West Seattle, the Central District or Rainier Valley can have very different rents, tenant demand and maintenance considerations.

A triplex has three dwelling units and can offer three income streams. Check the condition and marketability of each unit, not just the aggregate price. A property's advertised style does not independently confirm its permitted number of units.

Income and Expenses

Request leases, rent roll, deposits, actual collections, vacancy history, taxes, insurance, utilities, repairs and capital expenditures. Underwrite current income separately from projected rents and account for reserves.

Permits and Financing

Verify that all three units are legally established and that the unit count matches permits and lending documents. Ask your lender how the occupancy plan, property condition, appraisal and borrower qualifications affect available financing.

Residential 2-4 Units vs. Commercial 5+ Units

Duplexes, triplexes and fourplexes are commonly considered residential 2-4-unit properties for financing purposes, subject to lender requirements. Buildings with five or more units are typically underwritten as commercial multifamily. Compare Seattle fourplex listings or browse 5+ unit apartment buildings without mixing property categories.
