The Mansion District Fourplex is a charming 4-unit multifamily property nestled in the heart of Seattle’s desirable North Capitol Hill neighborhood next to Volunteer Park. Two units are nonconforming units, but can be permitted with SDIC as a value-add opportunity (buyer to verify). This historic gem, built in 1905, blends timeless appeal with modern potential, offering investors a rare chance to capitalize on one of the city’s most desirable areas. Whether you’re looking to boost rental income through market-rate adjustments, legalize the two lower non-conforming units for added value, owner-occupy a unit while generating passive revenue, or redevelop the site into higher-density housing, this fourplex is poised for substantial returns in a market where demand continues to outpace supply.
