Property taxes are based on the property value and not on the residentâ€™s origin, so as Mack correctly states, you will pay the same as anyone else for the same home.
When you sell your home, if you are foreign national, you may be subject to Foreign Investment Real Property Tax Act, aka FIRPTA which is a federal tax on gains while you owned the home. I've attached a link to IRS explanation of FIRPTA if this is what you were referring to.
Also, as mentioned, all sellers in the state are required to pay a 'resale tax'. If you are a foreign national selling, the IFRPTA tax comes into play. If you are an alien working in the USA with a SS number, you will need to fill out the FIRPTA form. In the state of Washington because we do not have an income tax, the state resale tax (in King County 1.78%) is collected at closing from your escrow account. yours Lindy Hisatomi
As in any sales transaction, you should rely on seasoned professionals with expertise in the area and in terms of escrow, a licenseced and bonded office.
