How Much Does It Cost to Sell a House in Washington State?

Most sellers I meet have a firm number in their head for what their home is worth and almost no number for what it costs to sell it. Then closing day arrives with a statement that surprises them. Let me give you the full picture for Washington state in 2026, so there are no surprises.

The real estate excise tax

Washington charges a real estate excise tax on every sale, and in practice the seller pays it. The rate is graduated: 1.10% on the first $525,000 of the sale price and 1.28% on the portion between $525,000 and $1,525,000, with higher brackets above that. Snohomish County adds its own share of about 0.50%, so on a $700,000 home the combined tax lands around $11,500. It is a real line item, and it is not optional.

Commission

Agent commissions in Washington are fully negotiable, and the typical total runs 5% to 6% of the sale price, split between the listing side and the buyer's side. On a home near the county median, that is $35,000 to $42,000. That is why the fee is a real conversation, not a formality, and why the value the listing side provides has to justify it.

Title, escrow, and everything else

Owner's title insurance, escrow and closing fees, recording fees, prorated property taxes, and any HOA transfer fees typically add another 1% to 2% of the sale price. Put together, a seller in Washington usually nets roughly 90% to 92% of the sale price before paying off the remaining mortgage.

The number that actually matters

Your net proceeds is what you walk away with, and it is the number your entire move-up plan hangs on. I build a net sheet for every seller before we list: sale price, minus excise tax, commission, title and escrow, the remaining payoff, and any seller credits, shown at two or three price points so you can see what a $10,000 difference in sale price means after costs.

Where sellers save real money

• Preparation that holds value: a pre-listing inspection and small repairs prevent last-minute credits from the buyer's side.
• Pricing that attracts the right buyer in the first weeks on market, so you are not chasing the market down with reductions later.
• Negotiating the commission like any other line item, with the value spelled out in writing.

Taxes, fees, and closing costs are not the exciting part of selling a home, but they are where the difference between a good outcome and a great one is decided. A seller who knows their net before the first showing has leverage the whole way through.

Before you list anywhere, ask for a net sheet. I will build yours with current, itemized numbers for your situation and explain every line. It is the first and most valuable step in pricing your move.
