Leschi Property Taxes (Seattle): The 2026 Homeowner Guide

Leschi runs along the western shore of Lake Washington, with terraced streets descending the hillside to a lakeside commercial node and a marina. Seattle's 2026 median assessed value is $833,000 at a ~0.99 percent effective rate, about $8,000 a year, but the bill on a Leschi home turns on neighborhood-level math.

If your property tax bill feels too high, the savings math below uses your own numbers. For a personalized review of your Leschi home (a comp pull, a property record check, and a real savings estimate), enter your address on the homepage. The review is free; Fair Appeal only collects a percentage of first-year tax savings when the appeal actually wins.

How are Leschi property taxes calculated?

King County reassesses every Seattle property every year, including every parcel in Leschi. The Assessor’s mass-appraisal model weights square footage, year built, lot size, and recent neighborhood sales, then applies the combined Seattle levy rate (around 0.99 percent for 2026) to the result. Voter-approved levies for schools, transit, parks, and city services layer on top of the state and county base.

What the model rarely picks up are the property-specific and Leschi-specific factors that buyers actually price into offers, and that is where most appeals are won. Anchored by Lakeside Avenue South, the Leschi marina, and Frink Park, Leschi’s housing stock has its own quirks the citywide model does not always capture.

Where does the Assessor get Leschi wrong?

Leschi's overassessment pattern centers on lake-frontage tier confusion. Homes on Lakeside Avenue South (directly fronting the lake), price in a different universe from homes a block uphill. The model occasionally pulls non-frontage homes upward into the frontage tier.

Identify your specific tier, direct frontage, second tier with view, or interior, and pull comps strictly from that tier. The price-per-square-foot delta between tiers is large, and mixing tiers in a comp set will weaken the case.

Leschi comps to Madrona (north, on the same hillside) and Mount Baker (south, similar terraced lake access). A tight comp set wins these cases.

What does a Leschi appeal actually look like?

Leschi homeowners appeal through the King County Board of Equalization, the same independent panel that hears every Seattle and King County appeal. The 2026 filing window runs through July 1, or 60 days after your Official Property Value Notice mails, whichever is later. The hearing is short, usually 15 to 30 minutes by phone, and the Board wants concrete evidence: comparable sales, documented condition issues, or an outright error in the property record.

For the broader Seattle context, see the Seattle property taxes guide or the 2026 King County property tax appeal guide.

Is a Leschi appeal worth filing?

At Seattle’s 0.99 percent effective rate, every $10,000 of assessed-value reduction is roughly $100 off the annual bill. A 10 percent reduction on a typical Leschi home (recent sale prices around $1,500,000, assessed values somewhat lower) pulls roughly $1,400 a year off the bill, and reductions tied to documented evidence often land larger. Most Leschi homes have at least one angle worth pursuing, the question is which one.

FairAppeal handles the full process from review through hearing, and only charges a percentage of first-year tax savings if the appeal actually reduces your taxes. the 2026 window is still open.
