How to Sell Your Home Without a Realtor in Washington State (2026)
With King County median home prices at $799,000, Seattle sellers stand to save more in raw commission dollars than almost any market in the country. At 6% commission on an $800,000 home that's $48,000 in agent fees. Selling FSBO keeps most of that in your pocket.
Is FSBO Legal in Washington State?
Yes. Washington homeowners have every right to sell without a real estate agent. Washington is an escrow state — closings are handled by title and escrow companies, not attorneys. No attorney is legally required, though one can be helpful for complex transactions.
Step 1: Complete Washington's Required Disclosures
Form 17 — Seller Disclosure Statement
Washington law (RCW 64.06) requires sellers to provide a completed Form 17 to buyers. This is the central disclosure document covering:Timing: Form 17 must be delivered within 5 business days of mutual acceptance of an offer. The buyer then has 3 business days to rescind if they don't like what they see. Best practice: complete Form 17 before listing and provide it proactively with your listing disclosure packet.

Factor this into your net proceeds calculation. Your title company files the REET affidavit at closing.
Step 3: List on NWMLS
Seattle uses the Northwest Multiple Listing Service (NWMLS) — one of the most robust MLS systems in the country. Flat fee MLS services can get you listed on NWMLS for $249–$399.
Important: Not all national flat fee MLS services cover NWMLS. Confirm NWMLS access specifically before signing up.
Step 4: Set Your Buyer's Agent Commission
Seattle buyer's agent commissions typically run 2–2.5%. After the NAR settlement, buyer compensation is more negotiable than before, but offering 2.5% still maximizes your exposure.
