King County’s median single-family home closed at $887,300 in late 2025. Chandler’s median for the same period sits at $565,000. That $322,300 spread isn’t just a number it’s the difference between equity locked inside four walls on a tight lot and equity converted into a significantly larger home, a lower property tax basis, and a six-figure cash position that didn’t exist before the sale.
The arithmetic behind the Seattle-to-Chandler move is straightforward. A King County homeowner selling at the approximate October 2025 median of $887,300 nets an estimated $834,000 to $838,000 after standard transaction costs of roughly 6%. Purchasing at Chandler’s 2025 annual median of $565,000 including standard Arizona closing costs leaves somewhere between $255,000 and $265,000 in retained equity. That capital can eliminate a mortgage entirely, fund a full renovation, or sit in a brokerage account compounding at a rate that simply wasn’t possible when it was embedded in a King County property.
That retained equity figure is the financial center of gravity for this move. It represents not a lifestyle upgrade, but a balance-sheet restructuring one in which the same housing dollar produces a materially better financial position.
The property tax dimension compounds the equity advantage over time. King County’s effective property tax rate runs approximately 0.92%, according to data from the Washington State Department of Revenue. On a home assessed at $887,300, that produces an annual property tax bill of roughly $8,163. Maricopa County’s effective rate runs approximately 0.52% (Maricopa County Treasurer). A Chandler home purchased at $565,000 generates an annual property tax bill of roughly $2,938 — a difference of approximately $5,225 per year. Over a decade, that annual delta compounds into more than $52,000 in cumulative savings, before accounting for assessed value growth on either side.
Estimated retained equity for a King County seller purchasing at the Chandler 2025 annual median, after standard transaction costs on both sides.
Calculation: NWMLS October 2025 median ($887,300) minus estimated 6% transaction costs = ~$834,000 net proceeds; minus Chandler median purchase price ($565,000) and standard AZ closing costs (~$10,000–$14,000)
A King County seller at the $887,300 median carries approximately $834,000 in estimated net proceeds into the Phoenix market. The table below maps that proceeds figure against Chandler’s current inventory across price tiers.
The pattern is consistent: a King County seller at or near the median can access Chandler inventory with two to three times the interior square footage of a comparable King County property, while retaining a six-figure cash position. A household selling at $1.0M to $1.1M in King County — common in areas like Bellevue, Kirkland, or West Seattle — can reach Chandler’s upper tier at $700,000 to $800,000 and still retain $150,000 to $250,000 in net equity after all transaction costs.

Property taxes are one of the most consequential and least discussed variables in the Seattle-to-Arizona relocation calculation. Washington levies no state income tax on wages, which can make King County homeowners underestimate the tax burden embedded in their current position. But property taxes are where the gap is substantial and it compounds every year of ownership.
Washington’s capital gains excise tax — enacted in 2021 and currently levied at 7% on long-term gains exceeding $250,000 annually — is a factor for King County homeowners who also hold investment accounts or business equity alongside their home. A King County homeowner realizing a $400,000 gain on a stock portfolio in the same year they sell their property faces a Washington capital gains liability of approximately $10,500 on the amount above the $250,000 threshold. Arizona has no equivalent standalone capital gains excise tax; capital gains are taxed as ordinary income at the 2.5% flat rate. For high-net-worth households running coordinated asset liquidation strategies, that differential is worth modeling with a tax advisor.

Chandler occupies the southeastern quadrant of the Phoenix Valley, positioned along the Loop 202 and US-60 corridors with direct access to the I-10 and Loop 101 interchange networks. The city’s housing inventory is a mix of established resale homes built primarily between 1990 and 2010, newer infill construction in the $550,000 to $700,000 range, and a limited supply of premium inventory above $800,000.
Median sold price (2025 annual): $565,000 Median days on market (September 2025): approximately 55 days HOA infrastructure: Present in a significant share of master-planned inventory; documented amenities typically include community pool, park, and ramada access New construction percentage: Mixed both established resale and active new development corridors Primary employment corridor access: Direct Loop 202 access to the Intel Ocotillo campus and adjacent semiconductor and advanced manufacturing employment node; US-60 access to Mesa and Tempe employment centers; approximately 20 miles from Sky Harbor International Airport via Loop 202
The Chandler market has been among the more stable in the Phoenix Valley on a price-per-square-foot basis. At September 2025, the average sold price for single-family homes was $663,032 reflecting the impact of upper-tier transactions while the median held at $550,500, indicating that the bulk of volume is transacting in the $500,000 to $650,000 range. For King County sellers with net proceeds in the $800,000 to $900,000 range, Chandler offers access to homes in the 2,800 to 3,600 square foot range a category that largely does not exist at comparable price points in King County.
A King County homeowner selling at the $887,300 median and purchasing in Chandler at $565,000 is not making a sacrifice on housing quality they are accessing a materially larger asset at a lower cost basis. The square footage differential between comparable-price King County and Chandler homes is significant.
At the King County median of $887,300, the average single-family home delivers approximately 1,600 to 2,000 interior square feet on a lot of 4,000 to 6,000 square feet, with limited outdoor coverage due to urban density constraints. At Chandler’s 2025 median of $565,000, inventory in the 2,400 to 3,200 square foot range on lots of 7,000 to 9,500 square feet is broadly available. At the $700,000 tier in Chandler well within reach for a King County seller at the median 3,200 to 4,000 square foot homes on lots approaching 10,000 square feet represent a substantial portion of available inventory.
That differential is purely a function of the equity gap. A King County seller is not buying a larger home in Chandler because Chandler is “cheaper” in any pejorative sense they are deploying the same equity into a market where land and construction costs produce a fundamentally different output for the same dollar.
Washington is one of Arizona’s top three sending states by annual migration volume. According to IRS Statistics of Income data for the 2021–2022 filing year, 16,600 Washington state residents relocated to Arizona making Washington the second-largest state source of Arizona-bound migration that year, trailing only California. Arizona’s net domestic migration gain of 36,714 in 2022 ranked seventh among all states nationally, and Washington-origin households represented a structurally significant share of that inflow.
The income profile of Washington-origin migrants reflects the financial character of the move. Washington residents who migrate carry above-average adjusted gross income relative to national averages reflecting the concentration of high-earning households in the Puget Sound region. Arizona’s IRS inflow data for the $100,000 to $200,000 AGI bracket the tier most likely to represent homeowning households with meaningful equity has accelerated faster than lower brackets in recent years, a pattern consistent with equity-driven relocation decisions rather than cost-pressure migration.
The Chandler-specific pull within the Phoenix Valley is structural: the Loop 202 / Intel Ocotillo corridor positions Chandler as a logical landing zone for households with semiconductor and advanced manufacturing backgrounds. That employment geography, combined with Chandler’s resale inventory depth and its position midway between the East Valley’s established grid and the newer inventory corridors further south, makes it a high-volume destination for Phoenix Valley new arrivals from the Pacific Northwest.
Washington state residents relocated to Arizona in the 2021–2022 IRS filing year the second-largest state migration corridor into Arizona that year.
