Buying a Duplex in Seattle

Seattle duplex investments vary substantially by neighborhood, building age and rental configuration. Confirm permitted units, current tenant agreements, utility arrangements, local rental requirements and realistic operating expenses.

Check property records, zoning, legal units, current rent roll, vacancy, taxes, insurance and repair reserves. A property advertised with an accessory dwelling unit is not necessarily a legal duplex.

Compare Nearby Duplex and Multifamily Markets

Residential duplexes are generally two-unit properties; commercial apartment buildings with five or more units require different underwriting and financing considerations.
