You've found a house you love, and it happens to be listed by an agent who is also happy to work with you. That sounds convenient. It can also put one person on both sides of a deal in which you and the seller want different things. It's called dual agency, and most buyers have never heard the term until they're asked to sign a form about it.
What Dual Agency Means
Dual agency happens when the same agent, or the same brokerage in some setups, represents both the buyer and the seller in one transaction. In many states it is only allowed with written consent from both sides. Rules and terms vary by state and by brokerage, so it's fair to ask any agent to explain exactly how it works in their situation.
Why It Creates a Conflict
Buyers and sellers want opposite things on price and terms. The seller wants the highest price and the cleanest deal, and you want the lowest price and the most protection. An agent representing both can't fully push for either. Advice like "you should offer $10,000 under asking" or "the seller would probably accept less" is exactly what a dual agent may not be able to give you.
That doesn't mean dual agency is always bad. Some agents handle it with great care, and in some cases it works out fine. But the buyer usually gives up the most, because the agent can't keep your budget, your motivation, or your strategy confidential from the other side.
What You Might Give Up
With one agent on both sides, the conversation about price changes. You may get neutral facts about the market but less advice about what you personally should do. Details you share about your budget or how much you want the house may be limited in how they can be used, or the agent may be required to keep them from both sides. Ask what that means in practice before you share anything.
If you're asked to sign a dual agency or "limited agency" form, read it, and ask the agent to explain in plain words what they can and can't do for you. You are allowed to say no and bring in your own agent.
Questions to Ask
Ask who exactly the agent is representing, and whether anything changes if you sign. Ask whether they can advise you on price, and whether they can keep your budget confidential. Ask what happens if you and the seller reach a disagreement. Then ask what it would look like if you had a separate agent. A good agent will answer without pressure.
The Simple Alternative
Having your own buyer's agent for a house listed by someone else is the cleanest way to have someone who works only for you. Your agent and the listing agent negotiate, and you get advice that isn't split. It's the same reason I explained in who the agent at an open house works for.
