Zillow's typical home value ran $776,196 (down 3.6% year-over-year), with Redfin-sourced medians carrying a real, disclosed spread of $743,000-$799,000 depending on the specific snapshot and property type -- genuinely more affordable than Seattle's own disclosed figures elsewhere in this build, though still well above the national median.
A genuinely high combined sales tax rate
Shoreline's combined 2026 sales tax rate is 10.5% (Washington's 6.5% state base plus a 4.0% city/local component) -- among the higher rates documented across this build's Washington Tier B markets.
Property tax follows the King County countywide rate
Shoreline's effective property tax rate runs at approximately 0.83%, the same King County countywide figure documented in this project's companion bellevue-wa.js record -- the highest countywide rate of Washington's 39 counties.
No state income tax, but a real capital gains excise tax on high earners
Washington has no state individual income tax, but its real, current capital gains excise tax applies to high earners: 7% on long-term gains above an annual threshold, rising to 9.9% above $1 million in gains as of the 2025 expansion.
