West of I-405, about three out of four Bellevue homes that sold between July 8 and October 5, 2026 closed below their final list price. East of the freeway the share was about three in five. Over the same 90 days, the typical West Bellevue sale closed at a median 96.7% of list. East Bellevue closed at 98.3%.
On a $1.5 million house, that gap of roughly a point and a half works out to more than $20,000 in negotiating room. Bellevue's citywide median can't show you this, because it blends two single-family markets that are moving at very different speeds. A third market, condos, behaves differently from both.
Where the freeway shows up in the data
The Northwest Multiple Listing Service splits Bellevue into two map areas. Area 520 is "Bellevue-West of 405" and area 530 is "Bellevue-East of 405." In the NWMLS September 2026 King County breakout, the two sides had nearly the same number of houses for sale. Very different numbers of them sold.
| Single-family, September 2026 | West of 405 (area 520) | East of 405 (area 530) |
|---|---|---|
| Active listings | 158 | 167 |
| Change in actives vs. Sept. 2025 | +44.95% | +51.82% |
| Pending sales | 25 | 51 |
| Closed sales | 19 | 51 |
| Median closed price | $2,720,000 | $1,550,000 |
| Median change vs. Sept. 2025 | -26.25% | 0.00% |
| Months of inventory | 8.32 | 3.27 |
Months of inventory is the figure that separates them. Divide active listings by monthly closings and you get how long the current supply would last if nothing new came on. West of 405, that was more than eight months in September 2026. East of 405 it was just over three. Across the whole NWMLS service area, supply hit 4.44 months in September, the highest level since February 2014. East Bellevue's houses are moving faster than the region as a whole. West Bellevue's are moving at about half the region's pace.
That 26% drop in the west-side median needs a careful read. It comes from 19 closings, compared with a September 2025 median of $3,688,000. With that few sales, a handful of large estates closing one year and not the next can move the median a long way. The figure shows which homes happened to sell. It doesn't show West Bellevue houses losing a quarter of their value. The supply and sale-to-list numbers are the more reliable signals here.
Why the west side has more room: price tier
The two halves of Bellevue sit in different price brackets, and those brackets are behaving differently across the whole Eastside.
A local brokerage's analysis of 1,455 Eastside residential sales from July 8 through October 5, 2026 broke results down by price range:
| Sale price, Eastside | Median % of list | Share sold below list | Typical discount when below list |
|---|---|---|---|
| Under $1M | 98.5% | 58.6% | 3.5% |
| $1M to $1.5M | 98.2% | 63.6% | 3.5% |
| $1.5M to $2M | 97.9% | 65.3% | 3.3% |
| $2M to $3M | 97.5% | 69.1% | 4.6% |
| $3M and up | 97.3% | 64.7% | 4.8% |
The jump happens at $2 million. Below that line, a buyer who negotiated a discount typically got about 3.5%. Above it, the typical discount rose to nearly 5%. East Bellevue's September median of $1.55 million falls squarely in the firmer middle tier. West Bellevue's $2.72 million median falls in the tier where buyers are scarcer and sellers concede more.
West Bellevue's own numbers fit that pattern. When a home there sold below list during the 90-day window, the typical discount was 4.7%. In East Bellevue it was 3.6%. The West Bellevue sample was 71 sales, below the 75-sale threshold the analysis flags as calling for extra caution. The direction still matches the NWMLS supply data.
Days on market changes the math on both sides
The analysis also tracked homes that sat 15 days or longer before going under contract. Those listings sold at a median 94.9% of list in West Bellevue and 96.5% in East Bellevue. In every Eastside area it measured, homes that went pending within seven days sold at a median 100% of list.
The difference in pace shows up in September's contract activity. East of 405, 51 homes went pending against 167 active listings. West of 405, 25 went pending against 158. On the west side, the 90-day analysis found the gap between fast-moving and slower listings was wider than anywhere else on the Eastside. Homes there that took 15 days or more sold at 94.9% of list, the lowest figure of any area in the study.
Price reductions are already common. Across the Eastside, 534 of 1,937 active listings, or 27.6%, had cut their price in the 30 days before the October 6 analysis. When a listing has already been reduced, part of the discount is built into the new asking price. That makes recent comparable sales a better guide to value than the size of the cut.
The pressure on both halves: rates rose all September
The two sides of Bellevue are moving at different speeds under the same financing conditions. According to NWMLS's October 6 market report, Freddie Mac's average 30-year fixed rate rose from 6.71% on September 3 to 7.03% on September 24, then to 7.28% in the first week of October. Steven Bourassa, director of the Washington Center for Real Estate Research, explained in that report why prices haven't fallen as fast as supply has grown:
"Prices tend to rise quickly in a strong market but can be slower to fall when conditions weaken, in part because sellers may have the flexibility to wait rather than accept a lower price."
That "downward stickiness" is visible in Bellevue. East of 405, the median held at exactly $1,550,000 year over year even as active listings rose by half. West of 405, the stickiness shows up as homes waiting longer on the market more than as lower list prices, which is why the 15-day-plus discount there is the steepest of any Eastside area in the analysis.
Condos are a third market, and new towers are entering it
Bellevue condos don't follow the freeway split. Both sides are well supplied.
- West of 405, September 2026: 127 active condo listings, 15 closings, 8.47 months of inventory, $836,000 median, up 16.92% year over year.
- East of 405, September 2026: 114 active condo listings, 15 closings, 7.60 months of inventory, $503,000 median, down 5.98% year over year.
Fifteen closings on each side is a small sample, and the west-side condo median in particular can swing with a few downtown tower sales. Regionally the trend is clear. NWMLS reported that condos slowed more sharply than single-family homes in September, and King County condos reached 7.05 months of inventory with a median price down 6.0% to $496,000.
New construction is arriving into that oversupply. In September 2026, Bosa opened sales at Park Row, a 22-story, 143-residence condominium tower at 10465 NE 2nd Street on the southeast corner of Bellevue Downtown Park, with prices starting in the $800,000s. That's within reach of the west side's September resale median of $836,000. Park Row sits a block from One88, Bosa's completed 21-story condominium building, whose ground floor holds Semicolon Café, Takai by Kashiba and Hästens. Across the street from One88, the City of Bellevue has approved 205 Tower, a 27-story, 142-unit building by Su Development on the former Sushi Maru lot, with construction estimated to start in fall 2026, as Downtown Bellevue Network reported on September 21.
For a downtown condo buyer, this means a resale unit is competing with presale inventory at nearby price points, on top of the eight-plus months of existing listings. The resale seller faces that same competition. It's a different situation from a single-family buyer in Lake Hills or Eastgate, who is shopping in the tightest segment of the city.
What the split means for comparing neighborhoods
Neither side of Bellevue is better than the other. They're running on different clocks right now. The same buyer, with the same financing, can expect a different negotiation depending on the side of I-405 and the property type:
- East of 405 single-family: about three months of supply, a flat median, and 98.3% of list at the median over the summer, and 51 pending sales in September.
- West of 405 single-family: more than eight months of supply in September 2026, 76.1% of recent sales below list, and the deepest discounts on homes that sit 15 days or longer.
- Condos on either side: seven to eight-plus months of supply, small monthly samples, and new-tower presales competing at the same price points downtown.
Office demand is also mixed. Downtown Bellevue office vacancy stood at 23.7% at the end of Q3 2026, but leasing was on pace for its strongest year in a decade, with about 755,000 square feet leased but not yet occupied. Those are commercial numbers, not homebuyer demand, and no source ties them directly to either side of the freeway.
Quick answers
Is Bellevue a buyer's market right now? It depends on the segment. In September 2026, West Bellevue single-family homes and condos on both sides had well over the roughly four months of supply NWMLS reported region-wide. East Bellevue single-family homes, at 3.27 months, were tighter than the region.
Why did the West Bellevue median fall so much? It was based on 19 September closings compared with a much higher September 2025 median. The mix of homes that sold changed. A drop that size from so few sales doesn't show a like-for-like value decline.
Does Park Row's pricing affect resale condo values? Park Row's prices starting in the $800,000s put new construction in the same range as September's $836,000 median for west-side resale condos. Appraisals and comparable sales still rely on closed resale data, so how presale pricing plays out will show up over the coming months of closings.
