What changed

A Washington estimate needs the sale-price tier and local REET. High-value transactions can be materially different from old flat-rate calculators.

Before

Washington used a flat state REET rate, with local REET added where applicable.

After

Washington applies graduated state REET tiers by sale price, plus any local REET. The statewide flat-rate shortcut is no longer safe for taxable sales.
