What makes Cottage Lake different
Home Value, By Source
The Census Bureau's American Community Survey (2023 5-year estimate) puts Cottage Lake's median home value — across all owner-occupied homes, not just recent sales — at $1,164,000. Separately, King County's current median listing price (via Realtor.com data, 2026-06-01) runs $850,000. These cover different geography (city vs. county) and different measures (assessed value vs. active listings), which is why we show both rather than picking one — full source list on our data sources page.
