Washington Homeownership Tax & Cost Tool
A monthly payment hides half the picture. Lay out the full Washington ownership cost - and the tax advantage that offsets it.
Tax and Wealth
Direct answer
Owning in Washington has a distinct Washington cost structure: no state income tax (a big plus for high earners), but property tax, insurance, and a graduated excise tax at sale. Lay it all out to plan on the whole number.
Work through the decision in order
Recurring
mortgage; King County property tax (rates vary - verify); insurance; HOA; utilities + maintenance reserve (M10).
At sale
WA REET (graduated - verify bracket).
The advantage
no WA state income tax (weigh the after-tax benefit vs. CA).
Your next move
Use the framework before the property creates urgency.
Bring the actual address, timing, financing assumptions, and open questions into a buyer strategy call before urgency takes over.
Current Washington tax policy
Separate the income-tax question from the property decision.
The enacted 2028 income tax does not replace Washington's capital-gains or estate taxes. Read the Eastside homeowner guide to the Millionaire's Tax and I-645 before treating any 9.9% headline as a home-sale tax.
