The Greater Eastside — Bellevue, Kirkland, Redmond, Mercer Island, Sammamish, Issaquah, and Woodinville — posted a full-year 2025 median single-family sale price of $1,599,000, according to Windermere Real Estate annual data compiled from NWMLS records. The Greater Phoenix median is $450,000. For Eastside sellers, this is not an equity gap — it is a structural financial reset. At the Eastside median, a seller can purchase at the Scottsdale median ($1,180,000), arrive debt-free, and still retain over $200,000 in cash. This guide shows you the exact math, the REET exposure specific to this price tier, and which Valley destinations fall within range at each Eastside price point.
The Eastside is not a single market — it is a range of submarkets spanning from Woodinville’s $1,281,000 median to West Bellevue’s $3,688,000 full-year 2025 median, as reported by Windermere Real Estate from NWMLS data. A single equity model does not serve every Eastside seller. This guide models three representative tiers so you can identify your position.
Estimated total REET (state + local) on the Eastside $1,599,000 median sale, calculated across Washington’s graduated schedule and King County local REET. This is more than double the REET on a King County overall median sale — a meaningful transaction cost that requires precise modeling before listing.

Sell at $1,599,000. Washington's graduated Real Estate Excise Tax at this price point crosses into the 2.75% tier — the most costly REET bracket for the vast majority of Eastside transactions. Total estimated state plus local REET: approximately $28,600. Combined agent commissions at 5.5%: approximately $87,945. Estimated net proceeds: $1,482,000 to $1,493,000.
At those net proceeds, an Eastside median seller can purchase at the Scottsdale median of approximately $1,180,000, close with standard Arizona costs of approximately $8,000, and retain approximately $295,000 to $305,000 in liquid equity after a zero-mortgage Phoenix Valley purchase — at the premium end of the Valley market.
Mercer Island's full-year 2025 median was $2,550,000, up 3% year-over-year per Windermere NWMLS data. At $2,550,000, estimated state plus local REET is approximately $59,500. Commissions at 5.5%: approximately $140,250. Estimated net proceeds: approximately $2,350,000.
At $2,350,000 in net proceeds, a Mercer Island seller can purchase at the Scottsdale median and retain approximately $1,162,000 in liquid capital — a financial position that fundamentally eliminates housing cost as a variable in household finances for years or decades.
West Bellevue's 2025 median sale price was $3,688,000, per Windermere NWMLS annual data — the highest single-community median in the Greater Eastside. At this price, the state REET alone is approximately $79,700 (with the 3.0% top tier applying to proceeds above $3,025,000). Including local REET and commissions, total transaction costs approach $280,000 to $295,000. Estimated net proceeds: approximately $3,390,000 to $3,410,000.
West Bellevue sellers are not buying into the Phoenix Valley — they are selecting within it. The relevant decision is not whether to carry a mortgage in Arizona, but which combination of Arizona properties, investment assets, or geographic diversification best serves the household's financial architecture.
| Community | Median Price | Est. Equity Retained | Note |
|---|---|---|---|
| Scottsdale | ~$1,180,000 | ~$1,162,000 | Full premium Valley purchase with seven-figure retained capital |
| Gilbert | ~$595,000 | ~$1,747,000 | Maximum retained liquid position |
| Luxury Scottsdale (North, guard-gated, custom) | $2M–$5M+ (custom range) | Varies with selection; partial deployment model | Custom / luxury segment; partial capital deployment |
The Mercer Island-tier seller represents the Eastside’s defining relocation profile: a household with enough net proceeds to purchase anywhere in the Phoenix Valley debt-free and retain seven figures in liquid capital. The decision shifts from “which community can I afford?” to “how do I deploy this capital most efficiently while establishing my Arizona property position?”
For households in this tier, the Equity Calculator and Relocation Equity Report are the appropriate starting tools. A West USA Realty agent consultation follows to map specific inventory against the retained capital model.
Est. Equity Retained:~$888K–$898K
Master-planned infrastructure, large lot inventory; maximum retained equity among established markets
Est. Equity Retained: ~$943K–$953K
Tech corridor access; deepest resale inventory
Est. Equity Retained: ~$295K–$305K
Premium Valley positioning; achievable at zero mortgage at Eastside median
Est. Equity Retained: ~$785K–$935K
Strong new-build Desert Ridge corridor; large retained capital
Est. Equity Retained: ~$1,053K–$1,063K

Price data: ARMLS, Phoenix REALTORS year-to-date 2025. Net equity estimates assume $28,600 REET, 5.5% commissions on $1,599,000 sale, and $8,000 in Arizona closing costs.
Washington’s Real Estate Excise Tax operates on a graduated schedule. Most Washington homeowners understand the 1.10% and 1.28% tiers from conversations about median King County transactions. Eastside sellers above $1,525,000 are in a different tier — and the mathematical impact is material.
Current Washington state REET tiers (state portion only):
| Sale Price Range | State REET Rate |
|---|---|
| $0 – $525,000 | 1.10% |
| $525,001 – $1,525,000 | 1.28% |
| $1,525,001 – $3,025,000 | 2.75% |
| Over $3,025,000 | 3.00% |
Source: Washington State Dept. of Revenue, current graduated REET schedule
The practical implication: every dollar of sale price above $1,525,000 is taxed at 2.75% at the state level — more than double the rate on the first $525,000. For a sale at the Eastside median of $1,599,000, the incremental amount above $1,525,000 ($74,000) generates $2,035 in state REET at the 2.75% rate — on top of $18,575 already accumulated in the two lower tiers.
For context: the same calculation on a King County overall median sale of $974,900 yields an estimated total REET of approximately $11,534. An Eastside seller at $1,599,000 pays more than twice that REET on a sale that is only 64% higher in price — because a material portion of the Eastside sale falls into the more expensive 2.75% bracket.
Total REET estimate on the Eastside $1,599,000 median sale versus the King County overall $974,900 median sale — the 2.75% tier on Eastside transactions creates a REET cost that grows disproportionately with price.
The REET increases substantially at higher Eastside price points: At $2,550,000 (Mercer Island 2025 median): estimated total REET ~$59,500 At $3,688,000 (West Bellevue 2025 median): estimated total REET ~$98,155
All REET figures are estimates. Final REET is calculated on the actual closing price and includes applicable local REET rates for the specific city or unincorporated area. Consult a Washington State real estate attorney or licensed escrow agent for exact figures prior to listing.
The income tax introduction applies here as it does for all Washington-origin households: Arizona charges 2.5% on all income, Washington charges none. For an Eastside household earning $300,000 combined, that introduction costs approximately $7,500 per year in new state tax liability. Model it in. It is real and it is annual.
With that established, the Eastside seller’s property tax arbitrage is the largest of any Washington origin submarket — because the asset being sold is priced far above the county average, and the asset being purchased in Arizona is priced substantially below it.
Running the numbers on an Eastside median seller purchasing at Scottsdale median ($1,180,000) on a household income of $300,000:
Annual income tax introduction (AZ 2.5% on $300K): +$7,500/year (new cost) Annual property tax savings ($1,599K WA → $1,180K AZ): ~$8,564/year (savings) Annual sales tax savings (10.5% → 8.4% on $80K spend): ~$1,680/year (savings)
Net annual fiscal position change (before equity deployment returns): approximately +$2,744/year favorable to Arizona
Estimated net annual fiscal improvement for an Eastside seller earning $300,000 purchasing at the Scottsdale median — after factoring in the income tax introduction and property + sales tax reductions.
For sellers purchasing below the Scottsdale median (Gilbert, Chandler, Mesa), the property tax savings are even larger relative to the income tax introduction, increasing the net annual favorable delta further.

The NWMLS Eastside encompasses multiple distinct price tiers. A Woodinville seller at $1,281,000 faces a fundamentally different equity calculation than a West Bellevue seller at $3,688,000. The profiles below treat each submarket as its own origin market with its own net proceed calculation and corresponding Arizona destination range.
Woodinville posted a 2025 median of $1,281,000, per Windermere NWMLS data. At this price, estimated total REET (state + local) is approximately $18,600. With commissions, estimated net proceeds land near $1,161,000. That net position purchases Gilbert or Chandler at the respective medians with more than $560,000 to $620,000 in retained equity, or reaches into the lower price points of the Scottsdale market with $0 mortgage and meaningful retained capital.
Redmond's 2025 market reflected softening from the Q2 2025 Windermere data, with prices running approximately $1.3M to $1.5M for single-family homes. At $1,400,000, estimated REET is approximately $22,500; net proceeds approximately $1,285,000. This tier reaches Scottsdale lower quartile inventory and all East Valley markets with substantial retained equity.
Kirkland's median reached approximately $2,190,000 in Q2 2025, up 8% year-over- year per Windermere NWMLS data. At $2,190,000, the estimated state REET alone exceeds $47,000 (with the 2.75% bracket applying to $665,000 of the sale above $1,525,000). Including local REET and commissions, total transaction costs approach $178,000. Estimated net proceeds: approximately $2,012,000. At this net position, Scottsdale at or near the median is a no-mortgage purchase with $825,000 to $835,000 in retained equity.
Mercer Island's full-year 2025 median rose 3% to $2,550,000, per Windermere NWMLS annual data. The REET calculation at this price crosses a full tier of the 2.75% bracket: estimated total REET approximately $59,500, commissions approximately $140,250. Net proceeds: approximately $2,350,000. Mercer Island sellers can approach the Phoenix Valley's luxury Scottsdale corridor, fund a custom North Scottsdale build, or purchase at any East Valley destination with retained equity exceeding $1.1M.
West Bellevue posted a 2025 full-year median of $3,688,000, making it the most expensive residential submarket in Washington State outside of waterfront parcels. At this price, the 3.0% REET tier applies to $663,000 of the sale above $3,025,000. Total estimated REET: approximately $98,155. With commissions, total transaction costs approach $280,000. Estimated net proceeds: $3,390,000 to $3,410,000.
For West Bellevue sellers, the Phoenix Valley question is not about affordability — it is about capital deployment architecture. The retained equity after any Arizona purchase is of a scale that warrants structured financial planning: which assets to hold in Arizona real estate, which to invest, how the estate tax exposure in Washington (if the estate is above $2,193,000) changes upon establishing Arizona domicile, and which Arizona submarket best serves the household's use case, whether primary residence, part-time use, or investment property. The Relocation Equity Report is the appropriate starting point for this tier.
The Bureau of Labor Statistics Consumer Price Index for the Seattle-Tacoma- Bellevue metro area runs 10% to 15% above the national average across recent annual measurement periods. The Phoenix metro runs approximately 3% to 6% above the national baseline. For Eastside households, the monthly housing cost differential is of a different magnitude than for typical King County or California-origin sellers.
An Eastside homeowner carrying a mortgage on a $1,599,000 home with 20% down at 6.5% carries an approximate monthly payment of $8,090. An Eastside seller who purchases at Scottsdale’s median with no mortgage carries zero monthly housing payment — a monthly cash flow event of $8,090. Over ten years, the cumulative housing cost reduction exceeds $970,000 before accounting for any investment return on retained equity.
Even for sellers who choose to retain a mortgage on the Arizona property, the delta is dramatic. A $500,000 Arizona mortgage at 6.5% carries a monthly payment of approximately $3,160 — roughly $4,900 per month less than the Eastside baseline. That $4,900 monthly differential, invested at a conservative 5% annual return, compounds to approximately $760,000 over ten years.
King County’s combined state and local sales tax in Eastside cities runs approximately 10.4% to 10.5%. Arizona’s average combined rate is 8.4%, per the Tax Foundation. On $100,000 in annual taxable expenditures — a reasonable figure for Eastside households — the 2.1-percentage-point reduction produces approximately $2,100 per year in additional purchasing power.
Washington is one of twelve states that imposes its own estate tax, independent of federal estate tax. Washington’s estate tax applies to estates with a taxable value exceeding $2,193,000 (2025 threshold, adjusted periodically for inflation), with graduated rates ranging from 10% to 20% on amounts above that threshold.
For Eastside households, this threshold is not a remote planning abstraction — it is a realistic financial variable. A household with a $2,000,000 Kirkland home, a $600,000 retirement account, and $400,000 in other assets is approaching Washington’s estate tax exposure at the household level. West Bellevue households with homes valued at $3M to $4M are typically well above it.
Arizona has no state estate tax. The federal estate tax exemption remains substantially higher than Washington’s threshold. For an Eastside household that permanently relocates to Arizona and establishes Arizona domicile, the Washington estate tax no longer applies to their estate — a potentially significant multi-generational financial benefit that falls entirely outside the income tax and property tax math modeled elsewhere on this page.
This is not legal or tax advice. Estate planning involves domicile law, trust structures, and other variables that require licensed legal and financial counsel. Households for whom this variable is material should consult an estate planning attorney before or during the relocation planning process.
