What Does a Realtor Do for a Buyer? (and What Should You Expect From Yours?)

by Brian Wittman

You get a standard you can hold your agent to after you sign, not a sales pitch. It's a short list of what they should be doing, what Illinois law says they owe you, and what was never their job in the first place.

Here's the part that's easy to miss. The pressure doesn't really hit at the first showing. It hits the day your offer's accepted.

Your contract starts a set of deadlines the moment it's accepted, and some of them are only days long. Somebody has to book the inspector, walk through the report with you and get your response where it needs to go in time. That's the job. That's what an agent is for.

What does a realtor do for a buyer?

Expect an agent to do things you can actually see, not just things they say. They should present every offer on time, tell you the material facts they actually know, put your interest ahead of their own, keep your confidences, account for your money and track every deadline in your contract. In Illinois, most of that is written into the Real Estate License Act. Don't expect them to be your attorney, your inspector, your appraiser or your lender, and don't expect a guarantee on value. A good agent shows you the work. A promise isn't work.

What do agents actually do for buyers?

The best proof isn't what an agent says they'll do. It's what buyers say their agent actually did.

NAR's 2025 Profile of Home Buyers and Sellers asked buyers exactly that, and here's what they reported:

54 percent said their agent pointed out features or faults with the home they hadn't noticed.
52 percent said their agent helped them understand the buying process, and for first-time buyers it was 76 percent.
45 percent said their agent negotiated better sales contract terms.
44 percent said their agent gave them a better list of service providers.
35 percent said their agent negotiated a better price on the house they bought.
27 percent said their agent shortened their home search, so they weren't looking as long.

Look at the order. It tells you something. The average agent's measurable value shows up in information and process first, and price comes further down. That's not a knock on anyone. It's a picture of where the job actually lives: helping you see the house clearly, understand what's happening and write an offer with terms that protect you.

So when you interview a real estate agent, you're hearing promises, and this list is how you check them after you sign. Ask yourself which of these six things your agent is actually doing for you. Then ask them about the rest.

What does Illinois law say your agent has to do?

Illinois spells it out in Section 15-15 of the Real Estate License Act. In plain words, an agent representing you has to:

(a)(1): do what your written brokerage agreement says they'll do for you.
(a)(2)(A): work toward a deal at your price and on your terms.
(a)(2)(B): present every offer to you and from you on time, unless you've waived that.
(a)(2)(C): tell you the material facts they actually know about the deal, unless it's someone else's confidential information.
(a)(2)(D): account for any money of yours they handle, including earnest money.
(a)(2)(E): follow your specific instructions, as long as they're lawful and don't break the rules.
(a)(2)(F): put your interest ahead of their own and ahead of anyone else's.
(a)(3): use reasonable skill and care in the work they do for you.
(a)(4): keep the confidential things you tell them confidential, during the deal and after it.
(a)(5): follow every fair housing and civil rights law that applies to your search.

Two more rules sit next to that list. Your agent has to give you a written disclosure of designated agency and talk with you about how the brokerage handles compensation (Section 15-35). And if they have any interest in a property, they have to disclose that to you in writing (Section 10-27).

Here's one people don't expect. Under 15-15(b), your agent can show the same house to another buyer and can even write a competing offer on it. But they have to tell you in writing, and you can ask for a different designated agent.

Now, what's not on that list matters too. Illinois law doesn't require an agent to show you every home on the market. It requires them to work toward your terms and put you first.

And look, the system has a quirk worth knowing. Under 15-15(c), a buyer's agent isn't presumed to be breaking a duty just because a higher price means a higher fee. Nobody in the transaction is paid to tell you to buy less. That's not an accusation. It's how the pay works. So your own number has to come from you, and from what you're approved for versus what you can actually afford.

What deadlines should your agent be tracking after your offer is accepted?

This is where proof beats promise fastest, because the clock is written down in your contract. The exact dates depend on the contract you sign, and they're often shorter than people expect. Here's the kind of deadline you'll usually see:

Attorney review: if attorneys handle closings where you're buying, yours gets a short window to approve the contract or propose changes.
Inspections: a window to get the inspection done and tell the seller what you want fixed, plus separate deadlines for things like a pest inspection.
Mortgage contingency: a date your loan commitment has to be in by. It's there so nobody drags their feet. In my experience, that date gets pushed back by agreement more often than not, because underwriting has run slower and more thorough since the 2008 crash. So your agent should be tracking it from day one, not finding out about it the week it's due.

You don't have to memorize any of that, but your agent should know your contract's dates cold. They should put the dates on your calendar the day you're accepted, get the inspector booked inside the window and make sure your attorney has what they need. Knowing how home inspections work helps you, but tracking the clock is their job.

What a clause means for your deal is your attorney's call, not your agent's. Every contract's different, so read your own and ask your attorney if you have one. And those first couple of weeks are only the start of everything that happens between your accepted offer and closing day.

What should you not expect from a real estate agent?

This half is what keeps the first half honest. A good agent knows where their lane ends. They'll tell you.

Don't expect legal advice. Your agent helps you build the offer, and your attorney, if you have one, tells you what it means.

Don't expect a guaranteed appraisal. The appraisal is part of the lender's process, and nobody on your side of the deal controls that number. An agent can bring comps and argue for the price. That's it. They can't promise it'll appraise, and if you're worried about it, it's worth knowing what happens if the appraisal comes in low before you write the offer.

Don't expect the seller's agent to look out for you. Under Section 15-25, they owe you honesty, which means no false information, and they have to disclose known latent defects. But they work for the seller. Not for you.

Don't expect anyone to steer you. An agent can't push you toward or away from a neighborhood based on race, religion, national origin, disability, familial status or any other protected class. That's banned by federal fair housing law, the Illinois Human Rights Act and the license act itself. What they can do is help you read the data on how to evaluate a school district and let you decide.

Don't expect your agent to get paid by your lender, title company or inspector. Federal law (RESPA Section 8) bans referral fees and kickbacks between the people in your settlement. If a referral comes with a business relationship, it has to be disclosed in writing, and you can't be required to use it.

That last one hits close to home. Here's why. There are real reasons why I hold three licenses, real estate, mortgage and Life Insurance, and one of them cuts both ways. If I recommend a lender, you should know it could be me, and you're free to shop. Hold any agent who recommends anyone to you to that same standard, me included.

How do you know if your agent is doing the job?

You watch what shows up. Week to week, without you having to chase it.

Do you hear about offers when they come in? Do you get the hard facts about a house, not just the good ones? Do the contract dates show up on your calendar before you have to ask about them? Does someone explain the next step to you before it happens, not after?

If the answer's yes, that's the job. If it's mostly reassurance, that's a promise. Your house is your biggest payment. Get it right, and the next five to ten years get easier.

The Bottom Line

An agent can say anything in an interview. After you sign, you get to see what they actually do.

Expect them to present your offers, tell you what they know, put you first, keep your confidences and track every deadline in your contract. Don't expect legal advice, a guaranteed appraisal or a recommendation that comes with a hidden payday. The standard isn't complicated. It's just easier to hold someone to when you know it ahead of time.

Frequently Asked Questions

Does a real estate agent have to show you every house?

No. Illinois law doesn't require an agent to show you every property on the market. Section 15-15 requires them to work toward your price and terms, present offers on time and put your interest first. If there's a specific house you want to see, just ask, and your agent can set it up.

Can my agent show the house I want to another buyer?

Yes. Under Section 15-15(b), an agent can show the same home to other buyers and even write competing offers. They have to disclose that to you in writing, and you can ask to work with a different designated agent.

Is my real estate agent supposed to review my contract?

Your agent helps you put the offer together and tracks its deadlines from acceptance on. If you're working with an attorney, they review what the contract means for you, usually inside a short window after acceptance. Check your own contract for the dates.

Can my agent get paid for sending me to a lender or inspector?

No. RESPA Section 8 bans referral fees and kickbacks between settlement service providers. If your agent has a business relationship with someone they recommend, it has to be disclosed in writing, and you're never required to use them.

Can a real estate agent guarantee the appraisal?

No. The appraisal is part of your lender's process, and nobody on your side controls the number. Your agent can support the price with comps, but they can't promise the result.

What's the difference between a realtor and a broker?

In Illinois, a broker is the state license that lets someone help you buy or sell a home. A Realtor is a licensed agent who's also a member of the National Association of Realtors and agrees to follow its Code of Ethics. You can check any agent's license on the IDFPR license lookup before you sign anything.

What should my agent tell me without being asked?

Offers as they come in, the material facts they actually know about the house, any interest they have in a property, and the dates your contract sets. Those aren't favors. Most of them are written into Illinois law.

If there's something you think belongs on the "expect" list, send it to me.

If you haven't hired an agent yet, set up a time and hold me to every line of this list, starting with the deadlines.
