The Most Expensive Homes Sold in Seattle Recently
A look at recent Greater Seattle luxury sales — Medina, Mercer Island, Madison Park — and why traditional percentage commissions on these homes are especially indefensible.
The luxury end of the Greater Seattle market is one of the most interesting case studies in real estate economics, because it’s where the percentage commission model breaks down most visibly. When a single transaction generates a $90,000 to $250,000 commission, the gap between “what the agent gets paid” and “what the agent did” becomes very hard to explain with a straight face.
This post looks at recent high-end sales in Greater Seattle and the commission economics behind them. We’ll update it periodically — bookmark the page if that’s useful.
A note on the data
Sale prices on luxury Seattle properties are public record once a transaction closes, accessible through the King County Assessor’s office and the Northwest MLS. We’re using publicly recorded sales here. Names of buyers and sellers are omitted out of basic respect — this isn’t a celebrity tracker.
Recent Greater Seattle luxury sales
Medina waterfront — high $20Ms
Medina has been the marquee zip code for tech wealth since the late ’90s, and it remains the highest-per-square-foot submarket in the region. Lakefront estates here routinely transact in the $15M to $40M range. A standard 2.5% buyer-side commission on a $25M sale is $625,000. The work involved in such a transaction — typically a small number of showings, a tightly managed inspection process, a quick close to a cash buyer — is no greater than on a $2M home, and arguably less.
Mercer Island — $8M to $15M range
The west-side waterfront of Mercer Island is the second tier of Seattle luxury. Sales in the $8M to $15M range have been steady through 2025–2026. A 3% listing fee on a $12M sale is $360,000. The listing agent’s job — pricing, photography, marketing, offers, escrow — is roughly the same as on the Ballard Craftsman they listed last week.
Madison Park & Washington Park — $4M to $9M
The lakefront strip of Madison Park and Washington Park sits firmly in seven-figure territory, with the strongest streets pushing $9M+. Inventory here is constrained, sales are often off-market or limited-marketing, and the homes typically sell quickly to known local buyers — meaning the listing-agent workload is even thinner than usual. A 2.5% listing fee on a $7M sale is $175,000.
Capitol Hill mansion district — $4M to $8M
The Federal Avenue mansion strip on Capitol Hill is one of the more historically significant residential corridors in the city. These are landmark properties, often with restoration considerations, but the actual transactional work is no different from any other listing.
Commission math at the high end
For luxury listings, our WA Homes Concierge tier is a flat $7,995 — same fee whether the home is $3M or $30M. It covers the genuinely heavier scope at the top of the market: vendor management, multiple opens, discreet marketing, hands-on staging, dedicated managing-broker oversight. The fee doesn’t scale with sale price because the work doesn’t scale linearly with sale price either.
| Sale price | 3% listing fee | WA Homes Concierge | Difference |
|---|---|---|---|
| $4,000,000 | $120,000 | $7,995 | $112,005 |
| $7,000,000 | $210,000 | $7,995 | $202,005 |
| $12,000,000 | $360,000 | $7,995 | $352,005 |
| $25,000,000 | $750,000 | $7,995 | $742,005 |
A $352,000 difference on a single $12M transaction is not a rounding error. It’s enough to fund a child’s college education. Twice.
”But high-end agents earn it”
This is the steel-manned defense of luxury commissions, and it’s worth taking seriously. The argument has three parts:
- Networks — the agent has a Rolodex of qualified buyers others don’t.
- Discretion — the agent can run a marketing process that respects the seller’s privacy.
- Negotiation — the agent is unusually good at handling sophisticated, often deal-hardened buyers.
These are real services. They cost real money to build and deliver — vendor relationships, photographer rosters, off-market broker networks, discreet showing logistics. Concierge bundles all of that into a flat $7,995. We charge for the work; we don’t charge a multiple of the home’s price.
The honest answer is that high-end agents have networks and discretion and a pricing model that has never been seriously challenged at the top of the market. Both can be true. The pricing model is the part that needs updating, not the work — and the work doesn’t 6x because the home is 6x more expensive.
What a flat-fee Concierge approach looks like at the luxury end
The most common objection we hear from sellers above $5M is: “wouldn’t a percentage agent fight harder for a higher price?” The answer, mathematically, is no — and even less so at the luxury end. On an $8M home at 3%, an agent makes $240,000. To push the price to $8.2M, they fight for an extra $6,000 on their side — a 2.5% raise on their fee. The gap between “their effort” and “your outcome” widens at every price tier.
Our WA Homes Concierge model — a flat $7,995, regardless of sale price — keeps the alignment honest. The work doesn’t scale with the home; neither does the bill. Same scope, same dedication, very different math.
