Snohomish County’s median single-family home price was $785,000 for full-year 2025, per the Northwest Multiple Listing Service 2025 Annual Statistical Report. The Greater Phoenix median is $450,000. That $335,000 spread, converted to net equity after Washington’s Real Estate Excise Tax and transaction costs, funds a debt-free purchase in most Phoenix Valley markets — with cash remaining. This guide models the equity position precisely for Snohomish County sellers and maps it against the six primary Valley destinations, including the honest accounting of where Scottsdale sits relative to these proceeds.
Snohomish County is Washington’s second-largest housing market by transaction volume, and one of the state’s most active sources of Arizona-bound migration. The financial equation here is distinct from both the King County and Eastside pages in this series: the 2025 annual median of $785,000 puts most Snohomish sellers below the $1,525,000 threshold where Washington’s REET escalates to 2.75% — a material transaction cost advantage compared to Eastside sellers.
Modeling the transaction from the NWMLS 2025 full-year median:
That net proceed figure purchases a home outright — no mortgage — in Gilbert, Chandler, Mesa, North Phoenix lower quartile, or Surprise/Goodyear, with meaningful retained equity in each case. What a Snohomish seller cannot do at the 2025 annual median is purchase at the Scottsdale median of $1,180,000 without carrying a substantial mortgage. This guide is explicit about that constraint and models it directly.
The strategic clarity for Snohomish sellers is this: five of the six primary Phoenix Valley destination communities can be reached with a zero-mortgage purchase. Retained equity ranges from approximately $121,000 in Gilbert to approximately $286,000 in Surprise and Goodyear. That retained capital can fund a renovation, build a reserve account, or be invested — none of which was possible when it was trapped in Washington real estate.
Net proceeds of approximately $721,872 map to the following destinations. All retained equity estimates assume standard Arizona closing costs of approximately $5,000.
A Note on Scottsdale: At the Snohomish County 2025 annual median, Scottsdale at the Valley median ($1,180,000) requires approximately $460,000 in financing or additional capital above net proceeds. This is not a disqualifier — it is a precision input. Snohomish sellers with homes priced above the county median (particularly Edmonds, Bothell, and premium Lynnwood properties in the $900,000 to $1,100,000 range) will have meaningfully higher net proceeds and a shorter financing gap.

Price data: ARMLS, Phoenix REALTORS year-to-date 2025. Net equity estimates assume $13,028 REET (state + local), 6% commissions on $785,000 sale, $3,000 pre-sale costs, and $5,000 Arizona closing costs.
Washington’s Real Estate Excise Tax escalates significantly once a sale price crosses $1,525,000, entering the 2.75% bracket — more than double the 1.10% rate on the first $525,000. This is the graduated REET reality detailed on the Eastside page, where sellers at $1.6M to $3.7M face REET burdens of $28,000 to $98,000.
A Snohomish County sale at the 2025 annual NWMLS median of $785,000 does not cross that threshold. The transaction falls entirely within the first two tiers — 1.10% on the first $525,000, and 1.28% on the remaining $260,000 — and stays well below the 2.75% escalation point.
Compare to the King County overall median ($974,900, REET ~$11,534) and the Eastside median ($1,599,000, REET ~$28,605): Snohomish sellers pay a proportionally lower REET not only in dollar terms but also as a percentage of sale proceeds, because the 1.10% and 1.28% tiers are less aggressive than the 2.75% bracket that Eastside transactions trigger.
Estimated total REET on a Snohomish County $785,000 sale — approximately half the REET on the Eastside median sale, because the transaction stays entirely within Washington’s two lower graduated brackets.

For Snohomish sellers above the median: The Bothell-area market (partly within Snohomish County) and premium Edmonds and Woodway properties can push sale prices to $900,000 to $1,100,000 or above. At $1,100,000, the total estimated REET (state + local) is approximately $18,000 — still entirely within the 1.28% tier and well below the 2.75% escalation point at $1,525,000.
The income tax introduction is the same for all Washington-origin households: Arizona’s 2.5% flat rate applies to income that Washington does not tax. For a Snohomish household earning $160,000 combined, that introduction costs approximately $4,000 per year. It belongs in every financial model. It is not a reason to abandon the move — but it must be counted.
Annual net fiscal modeling for a Snohomish household at $160,000 income, purchasing at the Chandler median ($540,000):
Estimated net annual fiscal improvement for a Snohomish County household at $160,000 income, purchasing at the Chandler median — after modeling the income tax introduction against property and sales tax reductions.
The income tax add-back is real and annual. The property and sales tax savings are also real and annual. At the Snohomish median price tier, the two largely offset, with a modest net position in Arizona’s favor. The financial case at this tier rests primarily on the equity redeployment event — not the ongoing annual tax delta.

For Snohomish sellers, the annual tax delta of approximately $1,459 in Arizona’s favor is real but modest relative to the scale of the equity event. The more consequential financial calculation is what happens to retained equity after a zero-mortgage Arizona purchase.
A Snohomish seller who purchases in Chandler at $540,000 with no mortgage and retains approximately $176,000 in liquid capital has three meaningful options:
Option 1 — Invest the retained equity. $176,000 deployed at a 5% annual return generates approximately $8,800 per year in passive income. That figure exceeds the annual tax delta and the projected property tax savings combined. Over ten years, assuming reinvestment at 5%, the compounded balance approaches $287,000.
Option 2 — Eliminate the mortgage payment entirely. The Snohomish seller currently carrying a mortgage on a $785,000 home with 20% down at 6.5% pays approximately $3,969 per month — $47,628 per year. A zero-mortgage Chandler purchase reduces that figure to zero. The combined property tax, HOA, and insurance on a Chandler home at $540,000 runs approximately $500 to $600 per month — a $3,369 to $3,469 monthly reduction in housing cost.
Option 3 — Reduce the Arizona mortgage. For sellers who prefer to retain more liquidity, a partial deployment of the $176,000 retained equity against an Arizona mortgage on a larger property produces a reduced monthly payment while keeping some cash in reserve.
In each scenario, the equity event produces a financial outcome that the annual income, property, and sales tax deltas cannot replicate. That is the case for Snohomish sellers: it is not built on a dramatic tax arbitrage but on the structural advantage of converting a Washington real estate asset into a lower-cost Arizona asset and keeping the difference.
Snohomish County’s internal price spread is significant. A Marysville seller and an Edmonds seller are both Snohomish County homeowners — but their net proceed calculations, REET exposure, and Arizona destination ranges are materially different. The profiles below map each major submarket to its Arizona outcome.
Marysville and Arlington represent Snohomish County's most affordable single-family markets, with median prices running approximately $550,000 to $640,000. At $590,000, estimated total REET (state + local) is approximately $9,800. Net proceeds land near $537,000 to $542,000. At this net position, Surprise/Goodyear ($430,000) is achievable with approximately $100,000 in retained equity. Mesa ($490,000) is reachable with approximately $42,000 to $47,000 retained. Gilbert and Chandler require either a small mortgage or a home priced above this submarket's midpoint. For sellers in this range, the Equity Calculator will show the precise crossover point.
Everett and Mukilteo account for a large share of Snohomish County's transaction volume and span a price range roughly consistent with the county median. At $725,000, estimated total REET is approximately $12,000. Net proceeds land near $665,000 to $670,000. At this position, Surprise/Goodyear and Mesa are zero-mortgage purchases with $225,000 to $230,000 and $170,000 to $175,000 in retained equity, respectively. Chandler becomes achievable with approximately $120,000 to $125,000 retained. Gilbert is within range with approximately $65,000 to $70,000 retained after a debt-free purchase.
This cluster of communities represents the heart of the Snohomish County market — consistently active, broad inventory, and prices close to or above the county annual median. At $800,000, estimated total REET is approximately $13,200. Net proceeds near $735,000. The full range of East Valley and West Valley destinations is reachable with zero-mortgage purchases and retained equity from approximately $130,000 (Gilbert) to $300,000 (Surprise/Goodyear).
Edmonds and Woodway represent Snohomish County's premium waterfront and bluff-view submarket, with median prices ranging from the high $800,000s to well above $1,000,000. At $1,000,000, estimated REET is approximately $16,400. Net proceeds near $920,000. At this net position, the full Valley range opens up: Gilbert with approximately $320,000 retained, Chandler with approximately $375,000 retained, and the lower end of the Scottsdale market becomes reachable for sellers in the upper quartile of this submarket.
Bothell's Snohomish County ZIP codes represent a submarket where price points approach and sometimes overlap with King County's overall median. At $1,050,000, estimated REET is approximately $17,100. Net proceeds near $966,000. Sellers at this price tier can reach Gilbert, Chandler, Mesa, and Surprise/Goodyear with $350,000 to $530,000 in retained equity, or target the lower Scottsdale price tier with a modest mortgage of approximately $220,000 to $230,000.
The Bureau of Labor Statistics Consumer Price Index for the Seattle-Tacoma- Bellevue metropolitan area runs 10% to 15% above the national average. The Phoenix metro runs approximately 3% to 6% above baseline. For Snohomish County households, the monthly housing cost delta is the most tangible financial change.
A Snohomish homeowner carrying a $785,000 home with 20% down at 6.5% pays approximately $3,969 per month on the mortgage alone. An equivalent purchase in Chandler or Mesa at $540,000 or $490,000 with no mortgage carries property taxes and insurance of approximately $450 to $550 per month total — a recurring monthly reduction of approximately $3,400 to $3,500. Over five years, that cash flow differential accumulates to approximately $204,000 to $210,000, independent of any investment return on retained equity.
Snohomish County’s combined state and local sales tax across its cities and unincorporated areas runs approximately 10.3%. Arizona’s average combined rate is 8.4% per the Tax Foundation. On $55,000 in annual taxable expenditures, the difference produces approximately $1,045 per year in additional purchasing power — persistent and cumulative.
One category where Phoenix is not cheaper: summer electric bills. Budget $250 to $400 per month from June through September for cooling a typical single- family home. Model this in. But also model out Washington’s rising utility costs and the property tax annual reassessment cycle that applies to all Washington properties at each sale.
Snohomish County is Washington state’s second-largest county by population and a significant source within the state’s Arizona-bound migration corridor. According to IRS Statistics of Income data for the 2021–2022 filing year, Washington state sent 16,600 tax filers to Arizona — the second-largest origin state in the nation after California. Snohomish County, as the state’s second- most-populous county behind King County, contributes a meaningful share of that figure.
The migration profile within IRS data is consistent with the Snohomish County market: households in the $75,000 to $200,000 income range, with established equity positions in single-family homes purchased in the 2012 to 2019 period, represent the largest segment of the Washington-to-Arizona cohort. Snohomish County homeowners who purchased at $400,000 to $550,000 in that window and have seen their homes appreciate to the 2025 median of $785,000 have captured between $235,000 and $385,000 in unrealized equity — equity that becomes deployable capital through an Arizona transaction.
The county was also identified as a top net source for Maricopa County in-migration in Arizona’s Economy analysis of IRS county-to-county data, consistent with its role as the second-largest population center in the Washington state corridor.
