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

Last updated: July 31, 2026 · By Tommy Mutchler, Real Estate Agent · Real Broker LLC, Whatcom County WA

The short answer: Selling a house in Washington usually costs about 7% to 9% of the sale price once you add up the real estate commission, the state and local excise tax (REET), and title, escrow, and prep costs. On a $650,000 Whatcom County home — roughly the Bellingham-area median in 2026 — that works out to somewhere around $46,000 to $52,000, before your mortgage payoff.

The real cost of selling a house in Washington, at a glance

When I sit down with a seller in Bellingham, Ferndale, or Lynden, the first question is almost always the same: "After everything comes out, what do I actually walk away with?" It's the right question — and the honest answer is that the sticker price on the sign is not the number that lands in your bank account.

Most Washington sellers lose roughly 7–9% of the sale price to the costs of selling. Here's how that breaks down for a typical financed sale where the seller offers to cover the buyer's agent:

The two lines that dominate that table — commission and excise tax — are worth understanding in detail, because they're where the real money is and where a little strategy goes a long way.

Real estate commission: your single biggest cost

For most sellers, the real estate commission is the largest cost of the entire transaction — usually far bigger than the tax bill. In Washington, total commissions generally run 5% to 6% of the sale price, and recent industry surveys put the statewide average in the mid-5% range (roughly 5.5%–5.9%). On a $650,000 home, 5% is $32,500 and 6% is $39,000. That's real money, so it deserves a real conversation.

There is no legally fixed commission rate in Washington — every rate is negotiable, and it always has been. What did change is how commissions are handled. Following the 2024 National Association of Realtors settlement (in effect since August 2024), a couple of things are now different for sellers:

• Sellers are no longer required to offer a commission to the buyer's agent. You can, and many still do to attract more buyers, but it's now an explicit choice rather than a built-in default.
• Buyers must sign a written agreement with their own agent before touring homes, which spells out how that agent gets paid.
• Commission offers are negotiated directly and can no longer be advertised through the MLS as a blanket promise.

In practice, most Whatcom County sellers I work with still split a total commission of roughly 5% between the listing side and the buyer's side, because offering competitive buyer-agent compensation widens the pool of people who can afford to make an offer. But the flexibility is genuinely yours now, and it's worth discussing openly with any agent you interview.

Washington's real estate excise tax (REET): the tax sellers owe

Washington doesn't have a state income tax, but it does tax the sale of real estate. The real estate excise tax (REET) is paid by the seller and is calculated on the full selling price. It comes in two parts: a graduated state rate and a flat local rate added by the county and city.

The state portion uses tiered rates, so higher-priced homes pay a higher rate on the top slice of their value. As of 2026, the state tiers set by the Washington Department of Revenue are:

On top of the state rate, local governments add their own flat REET. In Bellingham and across Whatcom County — including Ferndale, Lynden, Blaine, Everson, Nooksack, Sumas, and the unincorporated areas — the combined local rate is 0.50% of the full price.

Two things sellers often miss. First, because the state rate is graduated, a $525,000 sale is a meaningful pricing threshold — everything above it is taxed at the higher 1.28% state rate. Second, the Department of Revenue re-indexes these price thresholds every four years, so it's always worth confirming the current brackets on the Washington DOR excise tax page or checking the current local REET rate sheet before you sell.

Title, escrow, and other closing costs

After commission and excise tax, the remaining seller costs are smaller but still add up to a few thousand dollars. These are the fees that keep the transaction legal, clean, and correctly recorded.

Owner's title insurance. In most of Western Washington, the seller customarily pays for the owner's title insurance policy that protects the buyer against defects in the title. On a mid-range Whatcom County home, budget roughly $1,200 to $2,500 depending on price. Who pays this is technically negotiable and spelled out in the purchase agreement, so it can shift in a competitive market.

Escrow / closing fee. A neutral escrow company handles the money, documents, and signing. Its fee is commonly split between buyer and seller, leaving the seller with roughly $1,000 to $2,500. (In a VA-financed purchase, the seller may cover more of it.)

Recording, notary, and courier fees. Small line items — usually $100 to $500 total — to record the deed and release documents with the county.

Seller concessions. Increasingly common again: a buyer may ask you to credit them a lump sum at closing to cover their own costs or a rate buy-down. This isn't a fixed cost, but in a balanced market it's a negotiation point worth planning for, since it comes directly out of your proceeds.

Getting your home ready to sell

Prep is the one big cost you actually control, and it's where local strategy matters most. A Bellingham craftsman with original wood floors sells differently than a newer Ferndale build or a Lynden acreage property, and the right prep is different for each. The goal is never to over-improve — it's to remove the objections that make buyers hesitate or lowball.

• Deep clean and declutter: $150–$600, and the highest return on a dollar you'll ever spend.
• Minor repairs and touch-up paint: $500–$2,500 to address the small stuff an inspector or buyer will flag.
• Staging or a stager consult: $300 for a consult up to a few thousand for a full stage; often optional for occupied homes.
• Landscaping / pressure washing: $200–$1,000 — curb appeal genuinely moves the needle in our rainy season, when a mossy walkway reads as "deferred maintenance."

Costs sellers often forget

These don't show up on every sale, but they surprise people often enough to plan for:

• Mortgage payoff. Your remaining loan balance is paid off from the sale proceeds at closing. It isn't a "cost" of selling, exactly, but it's the single biggest deduction from your gross price — and any prepayment interest for the days before payoff is on you.
• Prorated property taxes. You owe property tax for the portion of the year you owned the home, prorated to the closing date. In Whatcom County that's a modest but real line item.
• HOA fees and transfer/document charges if your home is in an HOA — think Sudden Valley or many newer developments — plus any prorated dues.
• Capital gains tax. Most sellers owe nothing: a single filer can exclude up to $250,000 of gain, and a married couple filing jointly up to $500,000, on a primary residence they've lived in for two of the last five years. Above those thresholds, or on an investment property, gains may be taxable — a question for your CPA, not your agent.

A real example: seller's net sheet on a $650,000 sale

Here's how it all comes together for a financed sale of a $650,000 Whatcom County home where the seller offers a 5% total commission and pays customary closing costs. This is illustrative — your actual numbers depend on your price, your loan balance, and what you negotiate — but it shows the shape of a typical deal.

Figures are illustrative estimates for planning only, not a quote or a guarantee. Your net also reflects your remaining loan balance and prorated property taxes at closing.

How to keep your selling costs down

You can't avoid the excise tax, and cutting corners on marketing usually costs more than it saves. But there are legitimate levers that protect your bottom line:

• Negotiate the commission — and the service. Rates are negotiable. Ask exactly what's included, and whether a reduced buyer-agent concession makes sense given current demand for your home.
• Price it right the first time. The most expensive mistake in real estate is overpricing, sitting, and then chasing the market down with price cuts. Accurate pricing protects your net far more than shaving a fee.
• Spend prep dollars where they convert. Cleaning, paint, and curb appeal return the most; big remodels rarely pay for themselves right before a sale.
• Mind the $525,000 threshold. If your likely value sits just above it, understand that the top slice is taxed at the higher state rate — useful context when you set your list price.
• Get a real net estimate up front. Knowing your likely proceeds before you list prevents nasty surprises at the closing table.

Who pays closing costs when selling a house in Washington?

In a Washington home sale, the seller customarily pays the real estate commission, the full real estate excise tax (REET), the owner's title insurance policy for the buyer, and their half of the escrow fee. The buyer typically pays for their loan costs, the lender's title policy, their half of escrow, and their own inspection and appraisal. Almost all of it is negotiable and gets finalized in the purchase agreement — but that split is the Western Washington default you should plan around.
