Cost of Living in SeaTac: Housing, Taxes, Utilities & Lifestyle (2026)

SeaTac doesn't get credit for what it actually is: one of the last mid-priced entry points into King County's housing market. While neighboring Burien and Renton have climbed steadily, SeaTac's median sold price still hovers around $600,000 — a figure that reads almost like a misprint compared to Seattle's $865,000. That gap is real, and it's one of the most underappreciated financial stories in the south King County corridor.

What shapes the cost picture here is the airport. Seattle-Tacoma International Airport doesn't just define the city's employment base — it anchors the rental market, drives demand for housing within a short commute of the terminals, and keeps turnover relatively high in neighborhoods closest to the flight paths. That dynamic produces a cost structure unlike any other Seattle suburb: rents that run below the national average, a housing stock that skews toward 1970s-era construction, and a property tax rate that's noticeably higher than King County's own average.

This guide breaks down what it actually costs to live in SeaTac in 2026 — buying versus renting, what your property tax bill looks like, what the utility providers charge, and how the total monthly picture stacks up against Tukwila, Burien, Des Moines, and the rest of the neighboring cities you're probably also considering.

Housing Costs: Buying in SeaTac

The median sold price in SeaTac sits at approximately $600,000 as of late 2025, up about 2.6% year-over-year. At that price, buyers are typically looking at Craftsman, ranch, or traditional-style homes from the 1960s and 1970s — most of the city's housing stock was built during that era, and older construction is the norm rather than the exception. You're not getting new build finishes at this price point, but you are getting more square footage per dollar than anything north of Tukwila.

The market moves faster than most buyers expect. Average days on market have tightened to around 14 days, and competitive listings in areas like Angle Lake and near the Link light rail station often go pending within four days. The Redfin Compete Score for SeaTac sits at 85 out of 100, meaning multiple-offer situations are common and waived contingencies aren't unusual on the stronger listings. The Zillow Home Value Index for SeaTac is somewhat lower at $554,749 — that figure reflects estimated current value across the broader housing stock, while the $600,000 figure reflects what homes are actually closing for.

Buyers shopping in SeaTac will find the most meaningful price variation tied to proximity to the airport flight corridor and access to light rail. Condos and townhomes near SeaTac/Airport Station cluster in the lower-to-mid range, while larger-lot single-family homes in McMicken Heights and Angle Lake push toward and above the median. Here's how the budget tiers break out across the market.

Budget	What You're Likely to Get
$400,000–$499,000	Entry-level condos or townhomes, older ranch homes needing updates, smaller footprints near commercial corridors
$500,000–$599,000	3-bed/1–2 bath homes in established neighborhoods, 1960s–70s construction, good-size lots
$600,000–$699,000	Updated single-family homes, stronger neighborhood context, proximity to Angle Lake or North SeaTac Park
$700,000+	Renovated larger homes, lake-adjacent properties, best-condition McMicken Heights inventory

Property Taxes

SeaTac homeowners carry a property tax rate of approximately 0.98% — and on a $600,000 purchase, that translates to roughly $5,880 per year, or about $490 per month added to a mortgage payment. The effective rate is notably higher than King County's own average of around 0.83%, which means buyers moving from suburban Burien or Des Moines sometimes get a small surprise at closing. Washington State uses a levy limit system that caps annual property tax increases at 1% without voter approval, which provides some predictability for long-term owners. Homeowners aged 61 and older may qualify for King County's senior exemption program, which can reduce or freeze the taxable assessed value depending on income level — a meaningful benefit for retirees who choose to stay put.

Renting in SeaTac

Renters make up the majority of SeaTac's occupied households — roughly 55% of the city rents rather than owns — and the rental market reflects that balance with relatively diverse inventory across unit types and price points. The largest share of units falls in the $1,500–$2,000 per month range, which is consistent with what you'd expect for a market sitting about 10% below the national average.

Unit Type	Average Monthly Rent
Studio	$1,069–$1,365
1 Bedroom	$1,585–$1,593
2 Bedroom	$1,994–$2,013
3 Bedroom	$2,687–$2,791

Inventory skews toward apartment complexes rather than single-family rentals, and the highest concentration of apartment stock sits near International Boulevard and the airport corridor. Renters who need more space and a quieter residential feel tend to look toward the Bow Lake and McMicken Heights areas, where single-family rental homes are more common. The overall rental average of roughly $1,750 per month has remained relatively flat year-over-year, making SeaTac more stable as a rental market than many comparable Puget Sound suburbs that saw larger swings during the 2022–2024 cycle.

Utilities, Transportation & Daily Expenses

Electricity in SeaTac is split between two providers depending on where in the city you live. Homes north of South 160th Street fall under Seattle City Light, while properties to the south are served by Puget Sound Energy. Natural gas throughout the city runs on PSE. As of January 1, 2026, PSE implemented a rate increase of approximately 12% for electric customers — bringing a typical 800 kWh/month household bill to around $130 per month — along with a roughly 7% increase for natural gas customers. Combined utility costs in the Seattle metro area generally run in the range of $185–$270 per month depending on household size, usage, and which provider you're on.

Transportation costs are a meaningful variable here. SeaTac has direct Link light rail access at two stations — SeaTac/Airport Station and Angle Lake Station — making car-free commuting genuinely viable for workers heading to downtown Seattle, the University District, or Bellevue. The 20-minute commute to Seattle holds when you're on the train; by car on I-5, that same trip can stretch to 40–55 minutes during peak hours. Households that can eliminate a second car payment will see real monthly savings that offset some of SeaTac's higher-than-average property tax burden.

Grocery and daily errand access is centered primarily along International Boulevard (SR-99), which runs the length of the city and hosts most of SeaTac's commercial retail. The corridor includes a mix of international markets, chain grocery options, and fast casual dining that reflects SeaTac's diverse population. Residents in the northern parts of the city often supplement with shopping in Tukwila, where the Southcenter Mall area offers a denser retail cluster. SeaTac doesn't have the walkable downtown core that Burien has, and anyone expecting to stroll to a farmers market will need to recalibrate — this is a car-dependent city for most errands outside of light rail commutes.

SeaTac vs. Neighboring Cities

City	Approx. Median Home Price	Property Tax Rate	State Income Tax	Light Rail Access	Commute to Seattle
SeaTac	$600,000	~0.98%	None	Yes (2 stations)	20 min (rail)
Burien	$625,000–$650,000	~0.92%	None	No	25–35 min (car)
Tukwila	$560,000–$590,000	~0.95%	None	Yes (1 station)	20–30 min
Des Moines	$600,000–$640,000	~0.90%	None	No	30–40 min (car)
Renton	$625,000–$680,000	~0.97%	None	No	30–40 min (car)
Normandy Park	$750,000–$850,000	~0.88%	None	No	35–45 min (car)
Kent	$540,000–$580,000	~0.93%	None	Partial (Sounder)	35–45 min

SeaTac's clearest advantage over most neighbors is the combination of sub-$650,000 pricing and direct light rail connectivity — a pairing that only Tukwila comes close to matching. The catch, relative to Burien and Des Moines, is the airport adjacency: flight noise is a real factor in significant portions of the city, and buyers who don't account for it in their neighborhood selection sometimes regret the choice.

Sample Monthly Budget

The table below reflects a scenario at the $600,000 median sold price with a 10% down payment ($60,000), leaving a $540,000 loan.

Expense Category	Monthly Estimate
Mortgage Principal & Interest (7.0%, 30-yr)	$3,593
Property Taxes (0.98% annual rate)	$490
Homeowner's Insurance	$120–$160
HOA Fees (if applicable)	$0–$400
Electricity (PSE or SCL)	$100–$145
Natural Gas (PSE)	$55–$95
Internet (Xfinity/T-Mobile/Frontier)	$50–$90
Groceries (household of 2–3)	$600–$900
Transportation (1 car + Link pass)	$400–$650
Dining & Entertainment	$300–$500
Total Estimated Range	$5,708–$7,023

A household earning SeaTac's median income of $81,104 — about $6,759 per month gross — is looking at a tight ownership scenario at the median price with 10% down. That math works better for dual-income households or buyers putting closer to 20% down, where the elimination of PMI and the reduced loan balance bring the monthly total into more comfortable territory.

The Washington Tax Picture

Washington State has no personal income tax, which is one of the more significant financial advantages for SeaTac residents compared to buyers who might consider Portland-area suburbs or California locations. A household earning $81,000 in Oregon would pay approximately $5,000–$6,500 in state income tax annually — in Washington, that's $0, with no deduction or exemption required. The trade-off is a higher-than-average sales tax: SeaTac's combined state and local sales tax rate runs 10.2%, among the higher rates in King County. Everyday purchases, vehicle sales, and major appliances are all subject to that rate.

Washington also offers a senior property tax deferral program for homeowners 60 and older who meet income thresholds. Unlike the exemption program, deferral allows qualifying homeowners to postpone paying property taxes until the home is sold — useful for retirees on fixed incomes who want to age in place without a growing annual tax bill eroding cash flow. For long-term owners in SeaTac who bought when values were lower, the combination of no income tax and available senior deferral programs makes the overall tax picture more favorable than the headline 10.2% sales tax rate might suggest.

Local Expert Takeaway: SeaTac's real cost advantage isn't just the home price — it's the combination of that price with two light rail stations, a property tax rate that still sits below what you'd find in Bellevue or Kirkland, and Washington's zero income tax. Buyers who focus only on the airport noise and overlook the transit infrastructure tend to end up paying $80,000–$120,000 more in a neighboring city without gaining meaningfully better commute access. If you're a dual-income household where one person commutes to Seattle proper, run the full monthly math before you decide SeaTac "isn't quite right."

Quick Takeaways & FAQs

• SeaTac's median sold price of $600,000 is approximately $265,000 below Seattle's — the largest raw-dollar gap of any city with direct Link light rail access into the metro.
• Washington's zero income tax adds meaningful annual savings for households that would otherwise be paying Oregon or California state income tax, partially offsetting the 10.2% sales tax rate.
• Renter-majority city: With roughly 55% of households renting, SeaTac has a broader and more stable rental inventory than many south King County neighbors — and rents that sit below the national average.

Is SeaTac an affordable place to live compared to the rest of King County?

Yes, relative to most of King County, SeaTac offers genuine affordability. The median sold price of around $600,000 is well below the Seattle metro average of over $767,000, and rental rates sit approximately 10% below the national average. The combination of airport employment, light rail access, and competitive pricing makes SeaTac one of the stronger value propositions in south King County for buyers who don't need a walkable downtown.

What are property taxes like in SeaTac?

Property taxes in SeaTac run at approximately 0.98% of assessed value — higher than King County's average of around 0.83%, but predictable thanks to Washington's 1% annual levy increase cap. On a $600,000 purchase, expect roughly $490 per month added to your housing costs for taxes. Senior homeowners aged 61 and older may qualify for King County's exemption or deferral programs, which can reduce that burden significantly.

How does SeaTac compare to Burien for cost of living?

SeaTac and Burien are frequently compared by buyers in the south King County market. Burien's updated single-family inventory tends to clear at $625,000–$650,000 and doesn't offer light rail access, while SeaTac at the $600,000 median includes two Link stations. Burien has a more developed walkable downtown and lower airport noise exposure in most neighborhoods — so what buyers give up in SeaTac is the walkable commercial core; what they gain is direct transit access and slightly lower entry pricing.
