Should you let the listing agent represent you when you buy in Washington?

What limited dual agency means under Washington law

Washington’s agency statute, RCW 18.86.020, puts it in one line. When a firm appoints a broker to represent both the seller and the buyer in the same transaction, that broker is a limited dual agent.

The important word is “limited.” A dual agent still owes both of you the duties every Washington broker owes, such as honesty and reasonable skill and care. What gets narrowed is the part you hire a broker for in the first place: someone taking your side.

The law makes sure that is spelled out. Your consent has to include an acknowledgment that a limited dual agent may not advocate terms favorable to one party to the detriment of the other. The fuller set of rules sits in RCW 18.86.060, which covers, among other things, keeping each side’s confidential information to itself. If you want the exact wording, read the statute or ask a Washington real estate attorney. The short version is enough to make a good decision.

Same broker or same firm: the two versions

Most people picture the first version. The broker whose name is on the sign in the yard ends up representing the buyer as well. One person, working both sides of the table.

The second is less obvious. Your broker and the seller’s broker are two different people who work at the same firm. Each one represents only their own client. But the broker in charge of the firm, and the managing broker who supervises those two, now sit above both sides of the same deal, and Washington law treats them as limited dual agents for it. That is why buyer and listing agreements carry a second, separate consent for this situation.

In day-to-day practice the second version usually feels very different from the first, because each of the two brokers is still advocating for their own client. It comes up often at larger firms with many brokers working the same area. It still deserves a question before you initial it: ask how the firm keeps the two sides’ information apart.

What a dual agent can’t do for either side

Think about what you’d normally lean on your own agent for. Much of it goes quiet.

• Telling you how low the seller is likely to go. The dual agent may know, and can’t use it to help you.
• Advising you on your top number when they also know the seller’s bottom one. That is the conflict itself.
• Pushing for a price reduction after the inspection turns up a tired roof or an old electrical panel.
• Arguing your side when the seller wants a later closing and you need an earlier one.

A dual agent can still do a great deal: schedule, explain the forms, share the facts they’re allowed to share, keep the timeline moving, and present offers and responses faithfully. The same limits also run the other way. The seller gets less advocacy too, which is part of why both sides have to agree to it in writing.

When it can reasonably work

It can be reasonable when most of the hard questions are already answered: a buyer who has watched the neighborhood long enough to have a firm sense of value and mainly needs someone to handle paperwork and deadlines. It can suit an experienced buyer who has negotiated purchases before and would rather do that part personally.

It is harder to justify on a first purchase, on an older house with real condition questions (a 1910s place in Tacoma’s Stadium District, say, where the inspection is likely to find something), or anywhere you expect competing offers. Those are exactly the moments you want a person arguing for you.

Some buyers weigh all of that and still decide the convenience is worth it. That is a legitimate choice when it is made on purpose, after reading the consent, rather than in a hurry at the front door.

The consent you initial, and how to decline it

In Washington the consent lives in the written services agreement between you and the brokerage, the buyer agreement required since 2024 and explained in what a Washington buyer agreement has to say. There are two consents, one for each version above. The law requires the first, for one broker working both sides, to be initialed separately, and the form asks for your answer on the second as well. The seller gives the same kind of written consent in their own agreement.

Declining is simple. Leave the initials off, or tell the broker before you sign that you don’t consent. Then ask the practical follow-up: if you later want a house this broker or this firm has listed, what happens? Depending on the firm, you might be referred to a broker elsewhere, or the listing broker might continue to represent only the seller while you go without representation on that house. Know the answer before it matters.

You can also give one consent and withhold the other. A buyer might be comfortable with two separate brokers at the same firm while insisting that their own broker work only for them.

Calling the number on the listing: what to say first

This is where dual agency most often begins. You see a split-level in Bothell or a house with a view of Lake Washington, and you call the number on the listing because it is the fastest way through the door. The broker who answers represents the seller. They may be glad to show you the house, and early in the conversation they may offer to represent you as well.

If you already have a broker, say so in your first sentence and give their name. If you don’t and haven’t decided, something plain works: you don’t have an agent yet, and for now you’d like to see the house as an unrepresented buyer without consenting to dual agency. That keeps every door open. Until you’ve decided, keep your budget ceiling and your reasons for moving to yourself, since the person on the other end of the line works for the seller.

If you want someone whose only client in the deal is you, that is what a match through this site is built around: an introduction to an independently licensed agent who works your area. Before you hire anyone, it is worth a few minutes to look up their license with the Department of Licensing.
