Cost of Living in King City: Housing Prices, Taxes, and Grocery Costs (2026)

King City regularly surprises buyers who've been shopping Portland's eastside or Beaverton's newer subdivisions. At a median sold price hovering around $468,000, it sits below the Washington County average — but that number alone doesn't tell you much until you understand what the local housing mix actually looks like. A city where 55+ condos starting in the $160s coexist alongside detached single-family homes pushing past $500,000 means the "median" can mislead buyers who don't dig deeper.

What shapes the cost picture here is geography and demographics working together. King City occupies just 0.42 square miles in the Tigard-Tualatin corridor, with a median age north of 61 and more than 40% of residents aged 65 or older. That retirement-community character keeps housing demand moderate compared to family-driven suburbs, holds certain property types at price points you won't find anywhere else this close to Portland, and makes the rental market unusually thin.

This guide will walk you through what buyers and renters actually pay in King City in 2026 — from property taxes to utility bills, from the sample monthly budget of a median buyer to how King City stacks up dollar-for-dollar against Tigard, Tualatin, and Lake Oswego. If you're trying to decide whether King City's price points make sense for your financial picture, the numbers below will give you a clear answer.

Housing Costs: Buying in King City

The median sold price in King City sits at $468,000 — a figure that reflects an unusually wide housing mix for such a small city. At the lower end, attached condos and 55+ restricted units trade in the $159,000 to $315,000 range. Detached single-family homes, which make up the bulk of the desirable inventory, tend to list in the high $400s to low $500s, with the mean detached home value tracking closer to $507,000. Buyers accustomed to Portland pricing will recognize this as a relative value; buyers coming from smaller Oregon markets may find it steeper than expected.

Market tempo has moderated from the frenzied conditions of 2024 and early 2025. Homes now average roughly 82 days on market after a stretch where they were moving in 31 days flat. That cooling gives buyers more time to think — but the inventory is still thin, sometimes fewer than a dozen homes sold in a given quarter. When a well-priced detached home hits the market, it still draws multiple offers and frequently closes above asking.

One thing King City buyers should understand early: the small transaction volume makes any single month's median unreliable. The $468,000 figure reflects a reasonable working baseline, but you'll find months where the median swings $30,000 to $40,000 in either direction simply because only nine or ten homes changed hands. Work with current RMLS data for any specific offer decision.

Price Range	What You're Buying
$159,000–$315,000	Attached condos, 55+ restricted units, older townhomes
$380,000–$440,000	Smaller detached SFH, older builds, some deferred maintenance
$445,000–$520,000	Mid-range detached homes, updated interiors, typical King City purchase
$520,000–$580,000+	Larger lots, recent renovations, top of the King City market

Property Taxes

Washington County applies an effective property tax rate of approximately 0.99% in King City — meaningfully below the national median of 1.02% and well below many of the expensive California counties that Oregon frequently attracts buyers from. On the median $468,000 home, that translates to roughly $4,633 per year, or about $386 per month added to a principal-and-interest payment. Oregon's Measure 50, passed in 1997, caps assessed value growth at 3% annually regardless of market appreciation — which means long-term King City homeowners are often paying taxes on assessed values significantly below current market, a quiet but real financial benefit that compounds over years of ownership.

Renting in King City

The rental market here is smaller and less diverse than in neighboring Tigard or Beaverton. Because 81% of residents own their homes, available rental inventory skews toward apartment-style units and a limited number of single-family homes that investors have held for years.

Unit Type	Average Monthly Rent
Studio / 1-Bedroom	$1,550–$1,562
2-Bedroom	$1,747–$1,904
3-Bedroom	$2,100–$2,224
Single-Family Home (rental)	$1,400–$3,000+

The median gross rent in King City runs approximately $1,828 per month, which lands slightly below the national average for comparable metro-adjacent communities. That's the good news. The catch is that availability is constrained — when a unit opens up, it tends to move quickly, and prospective renters who need to move fast often find themselves looking at Tigard or Durham as overflow options. Rent has increased roughly 4.8% over the past year, consistent with broader Washington County trends.

Utilities, Transportation & Daily Expenses

King City's utility footprint is modest by Oregon standards. Natural gas and electric service come from NW Natural and Portland General Electric respectively. A typical household running gas heat, standard appliances, and air conditioning during summer months pays in the range of $180 to $250 per month combined, depending on the size of the home and the efficiency of the HVAC system. Water and sewer services run through Washington County Clean Water Services and Tualatin Valley Water District, adding roughly $80 to $120 per month for an average household.

Car dependency is real here. King City has minimal pedestrian infrastructure beyond the immediate neighborhood streets, and while TriMet bus routes connect to the broader Tigard-Tualatin grid, most residents drive. The 21-minute average commute to Portland is a genuine selling point — the SW Pacific Highway corridor (99W) provides a direct route, though it backs up during the morning rush between Tigard and Barbur Boulevard. Drivers heading into downtown Portland who leave before 7:30 a.m. typically hit the lighter end of that commute window; leaving after 8:00 a.m. adds 10 to 15 minutes. The Tualatin Valley Highway and I-5 interchange at Tualatin offers an alternative when 99W is congested.

Grocery access is handled primarily through Tigard. The Fred Meyer on SW Pacific Highway and multiple Safeway locations sit within a five-minute drive of King City's residential core. Costco, Trader Joe's, and Whole Foods are all accessible within the broader Tigard-Tualatin corridor. Residents who want walkable neighborhood coffee or dining largely drive into Tigard's commercial districts — King City itself has limited stand-alone retail. That said, the short drive distances mean this rarely becomes a daily friction point for residents who've planned their routines around it.

King City vs. Neighboring Cities

Understanding King City's cost position requires a direct comparison to the cities buyers typically consider alongside it.

City	Median Home Price	Avg Rent (2BR)	Property Tax Rate	Income Tax	Sales Tax
King City	$468,000	~$1,858	0.99%	Oregon (up to 9.9%)	None
Tigard	~$540,000	~$2,100	~1.02%	Oregon	None
Tualatin	~$545,000	~$2,050	~1.01%	Oregon	None
Durham	~$500,000	~$1,950	~1.00%	Oregon	None
Beaverton	~$510,000	~$1,980	~1.05%	Oregon	None
Lake Oswego	~$790,000	~$2,400	~0.96%	Oregon	None

King City's median price advantage over Tigard and Tualatin is real — roughly $70,000 to $80,000 below those immediate neighbors at the median level. That gap narrows when comparing detached single-family homes only (excluding King City's lower-cost condo inventory), but it doesn't disappear. For buyers who qualify for 55+ or attached product, the gap is even more dramatic. Lake Oswego, while offering lower effective property tax rates, carries price premiums that push the monthly ownership cost well out of reach for most King City buyers.

Sample Monthly Budget

This table reflects a purchase at the $468,000 median price with 10% down ($46,800), a 30-year fixed rate at approximately 6.75% (mid-2026 market conditions), and Washington County property tax.

Expense Category	Monthly Cost
Mortgage (principal + interest)	~$2,735
Property Tax (~0.99%)	~$386
Homeowner's Insurance	~$110
HOA (where applicable)	$0–$350
Electric + Gas	~$200
Water / Sewer / Garbage	~$105
Internet	~$65
Groceries (2-person household)	~$600
Transportation (fuel + insurance)	~$450
Dining Out / Entertainment	~$300
Total (no HOA) / (with HOA)	~$4,951 / ~$5,301

The median household income in King City of $66,728 works out to roughly $5,561 per month take-home before Oregon income tax withholding. At the no-HOA scenario, a buyer at that income level is spending approximately 89% of gross monthly income on the full budget above — which underscores why many King City buyers are either dual-income households, buyers who've liquidated equity elsewhere, or retirees with Social Security and pension income supplementing a lower earned income.

The Oregon/Washington Tax Picture

Oregon's income tax structure is one of the most significant factors in the Portland metro cost-of-living equation. The state applies marginal rates from 4.75% to 9.9%, with the top bracket kicking in at $125,000 for single filers. For the median King City household earning $66,728, the effective Oregon state income tax rate typically lands in the 7% to 8% range — meaningful, but offset by the complete absence of sales tax. For buyers relocating from California, Washington, or states with both income and sales tax, the no-sales-tax benefit tends to be felt most on large purchases: cars, appliances, furniture, and electronics.

Oregon also offers a property tax deferral program for seniors and disabled homeowners who meet income and age eligibility requirements. Qualifying King City residents can defer property tax payments as a low-interest lien against the home, payable when the home is sold — a meaningful cash-flow tool for residents on fixed incomes who own a home but face tight monthly budgets. Given that more than 40% of King City's population is 65 or older, this program gets real use here.

King City's overall cost of living index registers at 106.1 against a U.S. baseline of 100 — modestly above average, driven primarily by housing costs. Transportation, utilities, and groceries track close to national norms. For buyers comparing Portland metro living costs broadly, King City consistently comes in below the metro average despite being just 21 minutes from downtown.

Local Expert Takeaway: King City's 55+ attached inventory — condos and townhomes in the $160,000 to $315,000 range — represents one of the most overlooked entry points in the Washington County housing market. If you or your partner qualifies and you're not starting your search there, you're skipping a price tier that barely exists anywhere else this close to Portland. On the detached side, budget buyers should focus on the Jordan Way and King James Way corridors before those homes get bid up further by Tigard spillover; the $440,000 to $470,000 range still produces solid returns given the sub-1% property tax rate and Measure 50 protection.

Quick Takeaways & FAQs

• King City's median home price of $468,000 includes a wide mix — from 55+ condos in the $160s to detached single-family homes above $500,000. Know which segment you're buying in before quoting any median.
• The 0.99% effective property tax rate and Measure 50 protection make long-term ownership here significantly cheaper than the sticker price suggests — assessed values grow at only 3% annually regardless of market appreciation.
• Rental inventory is thin and turnover is slow — buyers who want flexibility should plan ahead, as King City's 81% homeownership rate leaves limited rental stock across all unit types.

Is King City affordable compared to the rest of the Portland metro?

By metro standards, yes — King City's $468,000 median sold price comes in roughly $70,000 to $80,000 below neighboring Tigard and Tualatin, and far below Lake Oswego. The 55+ condo inventory, starting under $200,000 for eligible buyers, has no real comparable in the immediate corridor. The overall cost of living index of 106.1 makes King City modestly above the national average, but it sits below most comparable metro-adjacent Washington County communities.

What are the property taxes like in King City?

Washington County assesses King City homes at an effective rate of approximately 0.99%, which produces an annual tax bill of roughly $4,633 on the median $468,000 home. Oregon's Measure 50 caps assessed value growth at 3% annually, meaning long-term owners pay taxes on a base that grows more slowly than market value — a compounding financial benefit that becomes more significant the longer you own.

How does King City's cost of living compare to Tigard?

King City typically runs lower than Tigard on housing — both purchase price and rent — while maintaining the same no-sales-tax and similar property tax environment. The catch is that Tigard offers significantly more retail, dining, and walkable amenity density. Most King City residents handle grocery runs and errands in Tigard anyway, which means the practical difference in daily access is smaller than the city-limit line suggests. For buyers prioritizing lower housing costs with easy access to Tigard's commercial corridor, King City often represents the better financial deal.
