Eastside Inventory Is Up 65%. So Why Aren't Prices Falling?
When the headlines say inventory is surging on the Eastside, buyers and sellers both ask the same question: if there are more homes for sale, why haven't prices dropped more?
It is the right question. And the answer lives in a single number that most market headlines never mention: months of supply.
Months of supply measures how long it would take to sell every current listing at the current pace of closings — with no new homes added. It is the most honest measure of the balance between supply and demand. And when you run it across all nine Eastside markets analyzed in the April 2026 NWMLS data, a clear picture emerges that no headline can summarize.
Seven of nine Eastside markets still have under four months of supply. That means inventory is up sharply — but demand is absorbing it faster than the supply can overwhelm prices. This is not a market in collapse. It is a market in recalibration.
Here is the data, neighborhood by neighborhood.

The Number That Explains Everything
Before diving into individual markets, here is the framework that makes sense of all the data:
Now apply that framework to every Eastside market. The chart below tells the full story.

More Inventory. Not Crashing Prices. Here Is Why.
The chart below makes the argument visually. Every market is shown with two bars — the inventory change (how many more homes are available vs. last year) and the median price change (what actually happened to prices). The disconnect is clear: some markets absorbed a 65% inventory surge with only a 3% price decline.
Chart 2 — Inventory Surge vs. Median Price Change by Market · April 2026 vs. April 2025
Navy bars = active listing % change YoY. Gold bars = median price % change YoY. Markets sorted by months of supply (tightest to loosest).

The Supply-Price Relationship: Visualized
The scatter chart below is the clearest illustration of why the inventory surge has not crashed prices across the Eastside. Each bubble represents one market. The X axis is months of supply. The Y axis is the median price change. The size of each bubble reflects closed sales volume — how many homes actually transacted.
The pattern is unmistakable: markets below 4 months of supply cluster near flat or positive price territory. The two outliers — Kirkland at 6 months and West Bellevue at 8.4 months — are the only markets showing meaningful price pressure. Everything else is holding.
Chart 3 — Months of Supply vs. Price Change · Bubble Size = Closed Sales Volume
Markets below the 4-month line hold prices. Markets above 6 months face real price pressure. Each bubble = one NWMLS area.

The Five Stories Inside the Data
1. Mercer Island: The Only Market Where Prices Rose
Mercer Island (Area 510) is the standout in this entire dataset. Active inventory actually fell 4.2% year over year — the only Eastside market where fewer homes were available in April 2026 than in April 2025. Pending sales surged 33.3%, from 21 to 28. And the median price rose 4.2% to $2,605,000.
Mercer Island continues to demonstrate that the combination of top-ranked schools, I-90 dual-commute access, and island community character creates a resilient demand floor that broader market softness has not been able to erode.
2. West Bellevue: The One True Buyer's Market
West Bellevue (Area 520, west of I-405) is the clearest buyer's market on the Eastside — and the data is unambiguous. Active listings rose 70.2%, from 84 to 143. Only 17 homes closed in April. Pending sales fell 23.8%. The months of supply sits at 8.41 — well into buyer's market territory. The median price declined 13.3% to $3,250,000.
This is a $500,000 discount compared to one year ago, in absolute dollar terms, in one of the most prestigious luxury markets in the Pacific Northwest. We will be covering West Bellevue in a dedicated comparison post shortly — including how it stacks up against East Bellevue and Mercer Island at comparable price points.
West Bellevue in context: A $3,250,000 median in a market with 8.41 months of supply means qualified buyers have real negotiating leverage right now. That leverage disappears the moment rates ease and the broader buyer pool returns. The question is whether the right property is available at the right price — and whether you are positioned to move when it appears.
3. East Lake Sammamish: Most Inventory Added, Prices Barely Moved
East Lake Sammamish (Area 540) had the highest absolute number of active listings of any Eastside market — 306 homes, up 65.4% from 185 a year ago. And yet the median price declined only 3.3% to $1,595,000, and 119 homes closed — more than any other luxury Eastside market in the dataset.
The reason is simple: demand absorbed the supply. With 2.57 months of inventory, buyers are active and deals are closing. The inventory surge here reflects normal market expansion, not distress.
4. Kirkland: Buyer Leverage Is Emerging
Kirkland and Bridle Trails (Area 560) crossed the 6-month supply threshold at 6.03 months — officially entering buyer's market territory. But the pending sales data tells a more nuanced story: pending contracts rose 34% year over year. Buyers are writing offers. They are just being selective, and the homes that are not moving are the ones that need to recalibrate on price or condition.
5. Issaquah/Newcastle: Largest Absolute Price Drop, Fastest Absorption
Area 500 (Issaquah, Factoria, Newcastle, Somerset) showed the largest median price decline in the dataset: −15% to $1,625,000. But with 2.63 months of supply and 64 closed sales — identical to last year — the market is not broken. What changed is the price tier, not the pace. Buyers at this level found value and acted. Days on market: 13 days. That is a fast market.
Where Buyers Are Acting — and Where They Are Waiting
Chart 4 — Pending Sales vs. Closed Sales % Change YoY · April 2026
Pending sales (gold) = current demand signal. Closed sales (navy) = completed transactions. Gap between the two reveals where buyer confidence is highest.
Information and statistics compiled and reported by the Northwest Multiple Listing Service.
Kirkland and Mercer Island stand out clearly: pending sales are up sharply in both markets despite overall softness. Buyers are writing contracts. The demand is there — it is just concentrated in specific properties that meet today's buyer's standards for condition, price, and location.
How Long Are Homes Actually Sitting?
Chart 5 — Average Days on Market: April 2026 vs. April 2025
Homes are taking longer to sell in most markets — but they ARE selling. Longer DOM reflects buyer deliberateness, not market paralysis.
Information and statistics compiled and reported by the Northwest Multiple Listing Service.
The Mercer Island spike — from 6 days to 45 days average — looks alarming until you account for the small sample (only 16 closings). One or two properties that took longer to sell can significantly move the average when the sample is this small. The demand signal from pending sales (+33.3%) tells the truer story.
West Bellevue actually shows a decrease in days on market (27 → 19 days), which seems counterintuitive for a buyer's market. The explanation: the homes that are selling in West Bellevue are moving relatively quickly — it is the homes that are not selling (reflected in the 8.41 months of supply) that are sitting indefinitely and not appearing in the DOM calculation.
What This Means If You Are a Seller
The inventory surge is real — but its impact on your property depends entirely on which of the nine markets you are in. A seller in East Bellevue (3.27 months of supply, −2.9% price change) is in a fundamentally different position than a seller in West Bellevue (8.41 months of supply, −13.3% price change) — even though both are listed under "Bellevue" in most headlines.
The strategic implication is the same in every market: price to where the market is today, not where it was in 2022 or 2023. The homes that are moving across the Eastside in April 2026 are the ones priced accurately. The homes sitting are the ones priced to a market that no longer exists at today's mortgage rates.
In the markets with under 4 months of supply — Bothell, Sammamish, Issaquah, Mercer Island, East Bellevue, Juanita, Redmond — sellers who price correctly are still transacting. The window is open. But with inventory continuing to build, the pricing conversation becomes more important with every month that passes.
What This Means If You Are a Buyer
The map above shows you exactly where your leverage is. West Bellevue at 8.41 months of supply is the clearest opportunity for a qualified buyer at the $3M+ price tier. Kirkland at 6.03 months is the most leverage-available option in the $1.5M–$2.5M range. Both markets are seeing motivated sellers and real pricing concessions that were simply not available 18 months ago.
The caution: the markets with 2–3 months of supply are still competitive. Bothell, Sammamish, and East Bellevue are absorbing inventory fast. Well-priced, well-presented homes in these markets are still attracting multiple showings and serious offers. Do not assume that a broad narrative of market softness means every market is equally soft — the data shows clearly that it is not.
