Isn’t sales tax when you buy something? And the buyer is usually the one who pays closing costs unless otherwise negotiated, right?
WA state already has a tax on the sale of real estate. They call it an excise tax. It is usually assessed on the seller of the home, unless the seller is moving out of state and then they assess the tax on the buyer. You usually don’t get a chance to contest it because you don’t even know about it before closing, unless you are up on real estate dealings.
