Buying Before You Sell in Washington: The Whole Picture
Program and regulatory figures verified September 19, 2026. Details change; confirm your scenario with us.
Everything a Washington move-up or move-down buyer needs to decide the order, in the order the decisions actually get made.
Step one: calculate what the sale actually produces
This is Washington's distinguishing step and it belongs first, because every structure downstream is funded by the answer.
Take your expected sale price and subtract state excise tax, calculated in brackets: 1.10% on the portion at or below $525,000 and 1.28% above that to $1,525,000, through December 31, 2026. Then subtract local REET of up to 0.50%. Then the existing mortgage payoff, commissions and closing costs.
On a Seattle-typical $727,359 sale, excise tax alone is roughly $12,000, about 1.65% of the price. That figure funds nothing and reduces everything. Run yours on the calculator, with the full walk-through on the net proceeds page.
Step two: the honest time on market, and it moved this year
For the month ending August 2026 the typical US home went pending in 53 days. Washington splits sharply by geography.
Puget Sound is fast: Bremerton 33, Seattle 39, Mount Vernon 39, Olympia 42, Bellingham 43.
Eastern and coastal Washington is not: Walla Walla 71, Aberdeen 70, Moses Lake 68, Ellensburg and Centralia 61, Yakima 59, Wenatchee 58.
And the direction matters as much as the level. Days to pending rose year over year in thirteen of seventeen metros, by 19 days in Walla Walla, 17 in Yakima, 15 in Aberdeen, 14 in Shelton, 11 in Kennewick and Moses Lake, 10 in Olympia, 9 in Spokane and 6 in Seattle. A plan sized against a neighbour's sale last year is sized against a number that has moved. Table on the market page.
Step three: the two-payment test
Can documented income support both housing payments at once, alongside your other obligations? That is the whole underwriting test, and it is unaffected by how much your sale will net.
Both questions have to work. Underwriting decides whether the file approves; net proceeds decide whether the exit works. Detail on the qualifying page.
Step four: choose the structure, knowing financing is untaxed
Because Washington does not tax the loan instrument, the choice between a bridge loan, a home equity line and a cash-out refinance turns on affordability, timeline and terms alone. That is simpler than in Virginia, where the instrument sets the rate, or Florida, where the lien is taxed on the full committed amount.
What is not simpler is the payoff, which still comes from the net number. See line versus term.
Step five: if you might rent the departing home
Renting defers the excise tax and removes the timing pressure, which in a slowing market has real appeal.
It also brings the property inside HB 1217. Increases are capped at 7% plus CPI or 10%, whichever is less, with Commerce publishing the annual figure: 9.683% for 2026 and 10% for 2027. No increase at all is permitted during the first 12 months of a tenancy, and 90 days written notice is required before any increase.
Exemptions are defined in RCW 59.18.710. We do not publish the list, and the rental conversion page explains exactly why.
Federally, for applications dated on or after November 1, 2026, B3-3.8-05 requires market rents rather than a lease and treats a positive figure as an offset against that property's own payment. Six months of PITIA reserves apply where property-management experience is under 12 months.
Step six: the loan limit, which is a short list
Three of Washington's 39 counties exceed the baseline, all at exactly $1,063,750: King, Pierce and Snohomish. Everywhere else, including Spokane, Clark, Thurston, Whatcom, Kitsap and Benton, uses $832,750. See the jumbo page.

Frequently asked questions
What is the first thing to work out when buying before selling in Washington?
What the sale will actually net. Excise tax of 1.10% on the portion at or below $525,000 and 1.28% above, plus up to 0.50% local REET, comes to roughly 1.65% of the price before the mortgage payoff, commissions and closing costs. Every structure downstream is funded by the number that survives those deductions.
How long does it take to sell a house in Washington?
It depends sharply on the region. For the month ending August 2026, mean days to pending was 33 in Bremerton, 39 in Seattle and Mount Vernon, 42 in Olympia and 43 in Bellingham, against 59 in Yakima, 61 in Ellensburg and Centralia, 68 in Moses Lake, 70 in Aberdeen and 71 in Walla Walla. The US benchmark was 53.
Which Washington counties have a higher conforming loan limit?
Three: King, Pierce and Snohomish, all at $1,063,750 for a one-unit property in 2026. Every other Washington county, including Spokane, Clark, Thurston, Whatcom, Kitsap and Benton, uses the $832,750 baseline.
Are Washington home values rising or falling?
Mostly neither. Over the year to August 2026, fourteen of the eighteen metros tracked sat between down 0.9% and up 1.2%, with Seattle weakest at down 1.5% and Centralia strongest at up 1.6%. It is the flattest state in this build round.
