Census and NOAA figures for the city of Mercer Island in King County, not the metro, with a source for each.
The median home in the city of Mercer Island was built in 1973, older than the U.S. median of 1980 and older than the Washington median of 1985.1 Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. Somewhat more of Mercer Island's housing predates 1980 than the national share: 61% against 50%, with 10% built since 2010.1 Owner-occupied homes in Mercer Island are older than rentals: a median build year of 1970 against 1982.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
Housing in Mercer Island is mostly detached single-family: 67% of units, with 32% in buildings of five or more units.1 A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 67% of occupied homes in Mercer Island are owner-occupied (64% statewide).1 The median owner-occupied home in Mercer Island is valued at $2,000,001 (ACS), above the Washington median of $564,600.1 Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
