If you own a property in King County, check out this website: http://localscape.property/#kingcountyassessor/.
It’s new from King County and you can find out so much information. Choose My Property, put in your address and then click on the blue button that says “View Proposed Taxes.” This will tell you how much any current tax levy on the ballot will affect you. Right now it’s showing info for August’s primary for Prop 1 – AFIS Property Tax Levy. For the several addresses I checked, the taxes will actually decrease from this one passing.
Let me know what you think of the site.
