On May 28, 2026, the Sound Transit Board did something quiet that changed the sale story on several West Seattle blocks. It approved an updated ST3 System Plan that keeps light rail coming to West Seattle, but with three stations instead of four. The Avalon Station is gone. More of the route moves into a tunnel. The agency identified over $2 billion in savings and fewer properties needed to build the line.
If you are thinking about listing near the Junction, Avalon, or Delridge over the next year, that vote already changed what you have to say on a Form 17 and what a well-prepared buyer will lean on at the negotiating table. The post below walks through what shifted, block by block, and how it interacts with a market that is still moving fast.
The disclosure that disappeared
The previous alignment carried two construction commitments that made a real difference to how homes within a few blocks of the alignment showed and priced:
- A planned one-year full closure of 35th Ave SW south of SW Genesee Street
- A one-and-a-half-year partial closure of Fauntleroy Way SW at SW Avalon Way
Both were tied to the Avalon Station box. Both were part of the material a thoughtful listing agent had to raise with any serious buyer, because they would have overlapped a typical five to seven year hold. With the Avalon Station eliminated, both closures are no longer part of the project.
For owners on the surrounding streets, this is the kind of change that does not show up in a comp report. A home on 36th SW near Genesee last November sat inside a construction-disclosure conversation. The same home this September does not. The public record of that shift is a single Sound Transit Board vote, and a sharp buyer's agent will know about it.
The blocks where the footprint tightened
The tradeoff is that the remaining Alaska Junction Station picks up a bit more work. Sound Transit's earlier station-access study analyzed a version of the Junction alignment that would require full acquisition of the Jefferson Square property, bounded by SW Alaska Street, 41st Avenue SW, 42nd Avenue SW, and SW Edmunds Street, along with a mix of business displacements east of 41st. Those specifics are not final until Sound Transit confirms design refinements with the Federal Transit Administration, but the direction is clear: fewer parcels overall, more concentrated at the Junction.
Local businesses have been named in the reporting for years. Ounces Taproom and Beer Garden and Mode Music Studios have both talked publicly about facing relocation. That is not a data point most sellers a few blocks away are tracking, but it becomes part of a buyer's mental map. When a couple walks the Junction on a Saturday, they notice which storefronts have "future of this block" energy and which do not. Pricing has to acknowledge that.
Here is how the current picture sorts out for a seller weighing a fall or winter listing:
| Block position | What changed May 28 | What to price against |
|---|---|---|
| 35th/Genesee and Fauntleroy/Avalon corridor | Multi-year street closures removed with Avalon Station | The old disclosure story is gone; comps from 2024–early 2026 were penalized for it |
| Inside the Alaska Junction Station footprint (roughly SW Alaska between 41st and 42nd) | Concentrated acquisition activity, tunnel portal work | Acquisition timing and TOD rezoning both live here |
| Delridge Station area near SW Andover | Aerial station work continues as planned | Buyers ask about construction staging, not displacement |
| Everywhere else in West Seattle | Indirect effect only | The "transit is coming" premium is broad and slow |
The mechanism most buyers already understand
The buyer side of this trade has read the same market pieces you have. Every Door Real Estate's 2026 outlook argues that with bridge repairs complete and light rail expansion moving forward, West Seattle list prices per square foot remain lower than comparable Seattle neighborhoods and that the gap is expected to narrow as transit connectivity improves. That is not a fringe view. It is roughly the same argument the City makes in its own station area planning, which frames the new station as an opportunity to grow West Seattle Junction as a transit-oriented neighborhood.
A well-prepared buyer will use that thesis as their offer floor and will pressure-test everything above it. They will ask which side of the alignment your home sits on. They will ask whether the block was inside an old closure zone. They will ask whether the parcel is in Sound Transit's acquisition footprint. They will ask about the Jefferson Square question. If the listing agent has not thought about those answers in advance, the seller is negotiating against their own information gap.
What the current numbers actually say
The most recent Redfin data for West Seattle covers the three months ending May 2026: median sale price $800,000, down 2.2% year over year, median 8 days on market compared with 6 a year earlier, an average of 3 offers per home, and a median price per square foot of $558. Houzeo's read of the same period puts months of supply at 0.68 and the sale-to-list ratio at 99.64%. Citywide, the August 2026 Beyond Real Estate report using NWMLS data shows a Seattle median of $869,500 with 13 median days on market and a 99.8% sale-to-list ratio.
Three things pop out when you interpret those numbers through the light rail lens rather than just reading the headline.
First, the small year-over-year price dip and the extra two days on market do not indicate a soft market. They indicate a market that is now willing to reward better preparation. When homes sell in eight days at 99.6% of list with three offers, staging and pricing strategy are still doing the heavy lifting, and any weakness in the disclosure story surfaces immediately.
Second, months of supply below one and a sale-to-list ratio just under 100% mean the buyer pool is deep enough that light rail proximity gets priced correctly rather than heroically. A home in the "closure is gone" zone should not expect a windfall. It should expect the penalty from the last two years to fall off.
Third, the citywide median sitting almost $70,000 above West Seattle's is exactly the gap that transit boosters point to. Whether it closes fast, slow, or not at all is a five to ten year question. Sellers deciding whether to list this fall are not really trading on 2032 service. They are trading on the near-term construction and disclosure dynamics between now and 2027.
The 12-to-18 month window
Construction is anticipated to begin in 2027 and Sound Transit is targeting 2032 for service. Between now and the first backhoe, three overlapping calendars matter to a seller:
- Property acquisition. Sound Transit will contact affected property owners, tenants, and businesses as more information becomes available. Owners in the concentrated Junction footprint should assume direct communication ramps through late 2026 and into 2027.
- City station-area planning. The Office of Planning and Community Development is running its Transit-Oriented Community Action Plan on a schedule that puts idea development in summer and fall 2026, with draft plan work extending into 2027. Rezoning conversations will shape what a redeveloper will pay for a well-located Junction parcel.
- Neighborhood capital projects that lift buyer confidence. Groundbreaking is set for fall 2026 on the small park at 4723 40th Ave SW, funded through $3.014M in Seattle Park District dollars, with a summer 2027 opening. Morgan Junction Park's expansion, refreshed at the May 13, 2026 open house at The Kenney on Fauntleroy Way SW, is moving toward late summer 2027 construction. An eight-story mixed-use building on 40th SW is expected to open in Q3 2026.
Layer those calendars together and the fall 2026 through spring 2027 window is where a seller has the cleanest story to tell: closures on 35th and Fauntleroy have been formally removed from the project, the Junction Station acquisition footprint is public knowledge but not yet visually disruptive, and the neighborhood is visibly investing in itself. Waiting until 2027 means selling into active property-acquisition news cycles and, on some blocks, early staging work.
A quick FAQ
My home is on 36th SW near Genesee. Do I still have to disclose the closure that was planned? The specific one-year full closure of 35th south of Genesee is no longer part of the approved project. General light rail construction impacts remain a fair topic for a Form 17 conversation, and Washington's seller disclosure requirements are worth reviewing with your attorney, but the specific closure that appeared in the earlier alignment is off the table.
Will an appraiser give me credit for the "gap will narrow" transit thesis? No. Appraisers work off closed comps. The value of the alignment change shows up in how many offers you draw and how tightly they cluster, not in the appraisal. That is why listing preparation and marketing carry more of the load in this window than a portal estimate suggests.
What if my property is in Sound Transit's acquisition footprint? Owners in the acquisition footprint have a different transaction path. The agency uses federal and state relocation rules, and timing is tied to the Board's project delivery decisions. That is a specialist conversation before you list on the open market.
Should I wait until service opens in 2032? That is a nine year hold with two construction phases in between. The cleaner comparison is fall 2026 versus fall 2027, not 2026 versus 2032.
Working the change into a listing
The May 28 vote is the kind of local detail that separates a well-run West Seattle listing from a generic one. If you own on or near the corridor and you are weighing this fall, we would rather have that conversation now, while the story on your block is at its clearest. homebysix works these details into pricing, staging, and marketing plans for owners across West Seattle and central Seattle.
