Washington State Licensed and Certified Appraisers serving the greater Puget Sound area.
AppraisalMS appraises Mercer Island homes for purchases, refinances, estates and date of death values, divorce and property tax appeals, working from our Lynnwood office. A quote starts with the island address in the box at the top of this page, or a call to (425) 967-3498.
The city is one island, about six miles long and up to four wide (Wikipedia). HistoryLink puts the population near 1,200 in 1940, when the first floating bridge opened, and close to 13,000 at incorporation in 1960. The 2020 Census counted 25,748.
Sound Transit's Mercer Island station opened March 28, 2026, in the I-90 median between 77th and 80th Avenues SE. Nearby homes have only months of sales since, so we weigh them carefully.
HistoryLink puts the business district at about 70 acres in the north central island. Condos and townhomes cluster here, and we compare them with other attached sales near the station first.
Calkins and Wood recorded this plat in December 1888 on the northwest shore, and it became the island's first town. Original cottages and recent rebuilds share streets here, so we keep them in separate comp sets.
Older houses here are being replaced; in 2016 the Reporter covered one lot on 74th Avenue SE split for three new homes. When a sale looks like a teardown, we test land value first and the house second.
The west shore faces Seattle and holds much of the island's prized waterfront, per Rexmont. Frontage, bank height, dock condition and the drop from street to house differ by lot, so we measure each.
The east shore looks toward Bellevue and the Cascades. Narrow lanes off East Mercer Way reach waterfront homes, like the Butterworth Road estate with 280 feet of frontage and moorage the Reporter covered in 2014.
Quieter and more wooded, with bigger lots, Rexmont says. Sales are fewer, so the comp search reaches further back and the report shows its time adjustment.
Water and land come before the house. Elevation runs from 18 feet at the shore to 394 feet near Rotary Park (Wikipedia), so view, slope and frontage separate homes that match on paper. City code caps a new house at 40 percent of lot area or a lower zone limit (MICC 19.02.020), and allowed coverage drops as slope rises.
On a hazard mapped slope the city may require a geotechnical report before any alteration (MICC 19.07.060), so we read the slope before giving a teardown lot full land value.
On the loan side we handle purchase, refinance and FHA work, ordered by the lender. Executors, attorneys and owners come to us directly for estate, divorce, pre listing and relocation reports. If the King County assessment seems high, our tax appeal guide walks through the steps.
Expect a friendly team, updates while we work, a clean, accurate report and delivery on the date we promised. Gerry has trained dozens of appraisers over three decades, and it shows on a lakefront lot: frontage and slope are measured in person, and each adjustment is written so a reviewer can follow it.
