Burien vs. Des Moines: Which South King County Market Fits Your Goals in 2026?

South King County has become one of the most searched value corridors in the Seattle metro — and for good reason. Burien and Des Moines both offer Puget Sound access, reasonable commutes to Seattle and the Airport Corridor employment cluster, and entry prices that run $200K–$400K below comparable waterfront or water-view inventory in Shoreline, Edmonds, or Kirkland. For buyers who've run the Eastside numbers and come up short, or for Seattle residents who want a saltwater lifestyle at a monthly payment that actually works, these two cities consistently emerge as the answer.

What's different about this comparison in 2026 is the number of tangible signals that both cities are changing. Des Moines is finishing the $8.5M Marina Steps pedestrian connection project — a transformation that will fundamentally change how walkable the Marina District is and how investors price waterfront-adjacent properties. Burien is executing on the North NERA rezone, which is opening up new townhome and mixed-use development north of downtown. Both cities are within 10–15 minutes of the Angle Lake Link station, which has improved the Seattle commute picture meaningfully since it opened.

This guide is built on transactions we've closed in both markets. We'll tell you the things that don't make it into the listing descriptions — the flight path reality, the neighborhood pockets that outperform the city-wide averages, and which buyer profile belongs in each city.

Three Tree Point is the most distinctive residential community in south King County — a private peninsula with no through traffic, homes ranging from modest non-waterfront to multi-million-dollar direct waterfront with dock rights, and a seclusion that's genuinely unusual this close to a major airport. The peninsula's west-facing orientation means unobstructed Olympic Mountain and Puget Sound sunset views. There is no comparable community between Mercer Island and Gig Harbor at this price tier. Buyers who discover Three Tree Point after looking at Mercer Island often find it delivers 70–80% of the waterfront experience at 40–50% of the cost.

Seahurst is more accessible — Seahurst Park's saltwater beach is public and free, the neighborhood has a mix of established single-family at $700K–$950K for non-waterfront and $1M–$1.5M for bluff view, and the community character is quiet and residential without the gated feel of Three Tree Point. For buyers who want Puget Sound access as a lifestyle element (sunsets, beach walks, kayaking) without the waterfront price, Seahurst is among the strongest value propositions in south King County.

Downtown Burien is worth attention in 2026 specifically because of the North NERA rezone. The 'North of NERA' district along SW 148th St — historically underutilized commercial zoning — is now approved for increased density including townhomes and mixed-use. Developers have already broken ground on projects that will bring new construction inventory to a walkable downtown core with coffee shops, restaurants, and SR-509 access. For investors and first-time buyers, pre-2027 entry in the North NERA corridor may represent one of the few remaining below-$600K opportunities in a walkable south King County location with improving transit access.

The Des Moines Marina District anchors the city's identity. The marina is the only full-service moorage between Tacoma and Shilshole Bay in Seattle — 700+ slips, a fishing pier, restaurants, and a waterfront park. The $8.5M Marina Steps project, currently in its final phase with December 2026 completion targeted, will add a pedestrian stairway connection between downtown Des Moines and the marina waterfront. For buyers who've watched the Marina District as a buy-now or wait question, the Steps project is the most concrete 'buy now before it fully prices in' signal in south King County right now. Marina-adjacent single-family currently prices $650K–$1.1M; the trajectory after Steps completion is unlikely to be flat.

Redondo Beach is Des Moines's most underappreciated sub-market. The Redondo boardwalk — a genuine waterfront promenade with a fishing pier, boat launch, and seasonal restaurants — has a beach-town feel that's rare in King County. The houses are a mix of older cottages and newer single-family, many with Puget Sound views, in a price range ($700K–$1.3M for water-adjacent) that is well below Shoreline or Kenmore waterfront. Buyers who want the emotional experience of living at the beach — weekend walks, salt air, boat watching — find Redondo delivers it at a price that doesn't require $2M+.

North Hill is the insider play in Des Moines that most buyers miss. The hillside above the marina — roughly the area between SR-99 and the Sound between 216th and 240th — has territorial Puget Sound views comparable to Normandy Park but at prices 15–20% lower because the school boundary shifts to Highline SD rather than Federal Way SD in parts of Normandy Park. When we have buyers who want Sound views and a manageable budget, we tell them to look at North Hill before they accept Normandy Park as the only option. They almost always find something that works. Woodmont, in south Des Moines near the Federal Way border, rounds out the city — quieter, more suburban, slightly lower pricing, and worth checking because some Woodmont addresses fall in Federal Way School District rather than Highline.

I want to address this directly because buyers who don't ask get surprised, and that's worse than having the conversation upfront. Both Burien and Des Moines sit under the Sea-Tac departure and arrival corridors. The noise is real, and any agent who waves it away is not giving you full information. The question is how significant it is for your specific location and tolerance — and that varies substantially by address.

The good news: the Port of Seattle operates the Sound Insulation Program, which provides window and door insulation upgrades to eligible single-family homes in the highest-impact noise corridors (DNL 65+ zones). Hundreds of Burien and Des Moines homes have been retrofitted under this program. A home with Sound Insulation Program upgrades has measurably better interior noise attenuation than one without. When we're helping buyers evaluate south King County inventory, we specifically ask whether a given home has received SI work — it's a free disclosure from the Port if you know to request it.

The pattern we observe in transactions: noise is most significant for properties closest to the SR-509 and SR-99 corridors (under flight paths) and least significant for hillside and peninsula properties (Three Tree Point, Seahurst bluff, Redondo) where elevation and topography create natural attenuation. Buyers who work unusual schedules and sleep during daytime hours should model this carefully — the day flight corridor is different from the quieter overnight period. For most buyers with conventional schedules, the noise fades into background quickly, and the trade-off for Puget Sound access at south King prices is one most report accepting without regret.

The Marina Steps project deserves more attention than it's getting from the general real estate press. Des Moines has always had the waterfront asset — the marina, the boardwalk, the fishing pier — but the lack of a direct, walkable pedestrian connection between downtown and the waterfront created a psychological separation. You drove to the marina; you didn't walk there. The $8.5M Steps project resolves that. When it opens in late 2026, downtown Des Moines will have a walkable waterfront connection that's genuinely comparable to what Edmonds has — a comparison that currently sounds like an overstatement but will read as accurate when the Steps are open.

The property value implication: Marina-adjacent Des Moines inventory has been pricing in anticipation of the Steps, but not fully. The last comparable infrastructure improvement in a south Sound city — the Edmonds ferry terminal plaza renovation — produced 8–12% appreciation in walkable-to-waterfront inventory over the three years following completion. We're not projecting that number for Des Moines, but the directional logic holds. Buyers who purchase Marina-adjacent Des Moines inventory at current pricing and hold through 2028 are acquiring an asset that will benefit from the completed infrastructure.

Burien's North NERA rezone is a different kind of signal — less about immediate lifestyle improvement and more about 5–10 year neighborhood trajectory. The rezone creates conditions for the kind of walkable density that has transformed neighborhoods in other Seattle-area cities (downtown Kenmore, downtown Bothell) from commuter-convenience stops into genuine destinations. Whether Burien executes on that potential depends on developer appetite and city follow-through, but the zoning foundation is now in place. For buyers willing to bet on neighborhood trajectory, North NERA-adjacent single-family is an interesting 2026 entry point.

Burien pricing in May 2026: entry-level non-waterfront single-family runs $640K–$800K with typical days on market around 18–22 days for well-priced inventory. Seahurst bluff view homes trade $875K–$1.45M. Three Tree Point waterfront ranges from $1.5M to $4M+. The spread reflects genuine submarket differences, not statistical noise — a buyer at $750K and a buyer at $2.5M in Burien are in completely different submarkets with different competition levels.

Des Moines pricing in May 2026: inland residential $540K–$760K, with slightly more inventory than Burien and slightly longer average days on market (22–28 days). Redondo Beach waterfront-adjacent $680K–$1.35M. Woodmont residential $590K–$860K. Marina-adjacent (below the Steps project zone) $620K–$1.1M with upside from the Steps completion baked into current pricing to some degree. Des Moines prices about 12–18% below comparable Burien tiers on a like-for-like basis — the persistent discount that reflects flight path exposure, school district, and the fact that Burien's commute to Seattle is measurably shorter.

On ROI: Burien has historically appreciated faster than Des Moines in absolute terms, driven by Three Tree Point waterfront scarcity and the shorter Seattle commute premium. However, Des Moines has outperformed Burien on a percentage basis in the 2021–2025 cycle because it started from a lower base and the Marina District improvements drove above-average gains. Investors watching both markets should note that Des Moines has more development-driven appreciation catalysts in 2026–2028 (Marina Steps, potential SR-509 transit improvements) than Burien's more mature market. Value investors favoring Des Moines; appreciation-certainty buyers favoring Burien is the framework we apply.

Both Burien and Des Moines are primarily served by Highline School District. This is the honest part of this guide that some agents skip: Highline SD ranks below the Eastside districts (Bellevue, Lake Washington, Northshore, Issaquah) and below Shoreline SD on most published academic performance metrics. Families who are making their south King County choice primarily on school quality should be aware of this before they commit to the geography.

Where Highline has made genuine progress: graduation rates have improved significantly over the last five years, and specific schools within the district — Mount Rainier High School in particular — have developed academic programs (including IB and Running Start) that provide motivated students strong college preparation. Highline is not a district to categorically dismiss, but it requires more homework than Northshore or Bellevue SD, where quality is more consistent district-wide. Buyers should look at the specific school pathway for their address, not just the district name.

For families who prioritize school quality above other variables, south King County's value case weakens — and the honest answer is to buy in Northshore SD (Bothell/Kenmore), Lake Washington SD (Kirkland/Redmond), or Issaquah SD at higher price points, or accept that private school will be part of the cost structure. For families where school is a factor but not the primary driver — where the waterfront lifestyle, lower monthly payment, and proximity to the Airport Corridor employment cluster matter more — Highline SD is manageable and improving.

The Angle Lake Link Station — the southern terminus of the 1 Line, opened in 2016 and still the relevant transit lifeline for both cities — sits at S 200th St in SeaTac, about 10–15 minutes from most Burien and Des Moines addresses. For buyers who commute to downtown Seattle or Capitol Hill by rail, this is the anchor of the transit story. Seattle's Westlake station is 25 minutes from Angle Lake; University of Washington is 22 minutes. For a 3–4 day hybrid Seattle commuter living in Des Moines or Burien, the transit math is competitive with living in many Seattle neighborhoods that require a bus-to-rail transfer anyway.

By car: Burien to downtown Seattle via SR-509 runs 20–30 minutes outside of peak (excellent) and 35–50 minutes during peak (acceptable). This is the best commute story in south King County and a significant reason Burien prices above Des Moines — the SR-509 corridor gives Burien residents a non-freeway route into SODO, SoDo, and the stadiums district. Des Moines to Seattle via SR-99 or I-5 runs 25–40 minutes off-peak and 40–60 minutes peak — longer and more variable, with less freeway-bypass optionality.

The Airport Corridor employment cluster — Sea-Tac Airport itself, Boeing Renton (SR-900, 20 minutes), the Southcenter/Tukwila commercial district, and the growing industrial/logistics corridor along I-405 — is genuinely local for Burien and Des Moines residents. Buyers who work in this cluster and have been searching north of the airport often find they're commuting 45 minutes past their office. For Airport Corridor workers, south King County is not a compromise — it's the optimal address.

Buy in Burien if: you work in downtown Seattle and want the shortest possible commute with Puget Sound access (SR-509 is the answer), Three Tree Point's exclusivity and waterfront access is the lifestyle you're buying, you want the stronger long-term appreciation track record of the two cities, or Seahurst's beach-community feel at a manageable price point fits your budget. Burien is also the right answer for buyers who want the most walkable downtown experience in south King County — the restaurant and bar scene on SW 152nd St has improved meaningfully in the last three years.

Buy in Des Moines if: marina access and live-aboard or boating lifestyle is part of your plan, you want waterfront character (Redondo's boardwalk, the Marina District) at 12–18% less than comparable Burien tiers, you're buying at entry level and want more square footage per dollar south of the airport, or you believe in the Marina Steps trajectory and want to buy into the appreciation story before December 2026 completion. North Hill is the specific sub-market recommendation for buyers who want territorial Sound views on a budget — call it Normandy Park quality at Des Moines pricing.

Both cities share the flight path reality, the Highline SD consideration, and the Angle Lake Link station as the transit backbone. These are not dealbreakers for most buyers who've thought about them honestly — they're the variables that explain why south King County prices where it does relative to the north end of the lake, and why buyers who understand the trade-offs and make the choice deliberately are typically very satisfied. The buyers who regret it are almost always buyers who were surprised by the noise or the schools because no one walked them through it before they closed.
