How to Know If You're Getting Good Real Estate Agent Advice

The advice you get from an agent is the product you are paying for. Sellers know it: 42% of 2026 sellers said the single most valuable thing their agent did was help them “price my home and/or understand my local market,” and 67% put it in their top two. (Zillow Consumer Housing Trends Report 2026, Sellers) The problem is that bad advice and good advice sound alike in the moment. Both are delivered confidently by someone with a license. The difference shows up months later in the price, the days on market, or the repair bill. This post gives you a way to tell them apart before that happens.

Good advice has five properties

Test one: is there evidence attached?

Pricing is where this matters most. A list price recommendation should come with the comparable sales it rests on: at least three recent closed sales, their dates, their distance from your home, and the adjustments the agent made for size, condition, and features. If the agent cannot show you that, they are guessing, and the guess is usually anchored to what wins the listing rather than what sells the house.

Here is why the evidence matters. Nationally, the median home sold for 98.5% of its final list price in September 2026, 19.8% of listings had at least one price drop, and the median home took 51 days to sell. (Redfin) NAR’s 2025 Profile puts the median sale at 99% of the final listing price, with 27% of sellers offering incentives to attract buyers. (NAR 2025 Profile of Home Buyers and Sellers) Notice the word “final.” Those figures measure the price after reductions. A home listed too high and cut twice still shows as 99% of final list. The cost of the bad advice is hidden in the cuts and the extra weeks, not in that ratio.

Automated estimates are not evidence either. Zillow reports its own estimate has a nationwide median error of 1.77% for homes already on the market and 7.20% for off-market homes, and states that it “is not an appraisal and can’t be used in place of an appraisal.” (Zillow, What is a Zestimate?) Before a home is listed, a 7.2% median error on a $300,000 house is about $21,600 either way, with half of estimates missing by more than that. An agent who prices from an online estimate instead of closed comparables is not advising you; they are reading you a number you could have looked up yourself.

Test two: does the advice include its own downside?

Honest advice names what could go wrong. “List at $329,000; if we have no showings in the first ten days, the market is telling us something and we drop to $319,000 on day fourteen” is advice with a downside and a plan. “List at $345,000, we can always come down” is advice that ignores what coming down costs. Research on relisted homes found that short gaps between listings “lead to longer total marketing periods, suggesting market skepticism of superficial resets.” (Hayunga and Swymer, Journal of Housing Economics, 2025) Buyers notice stale listings, and the first two weeks are not recoverable.

For buyers, the same test applies to the advice to waive an inspection, skip an appraisal contingency, or escalate above the number you were comfortable with. Each can be right in a specific situation. Each has a downside, and an agent who does not say it out loud is leaving you to discover it.

Test three: does the agent tell you when their interest differs from yours?

This is the test most agents fail, not from dishonesty but from habit. Economists Steven Levitt and Chad Syverson found that agents selling their own homes “stay on the market almost 10 days longer and sell for about 3.7 percent more than comparable houses owned by the people who hire real-estate agents to represent them.” (NBER Digest) The explanation is simple: an extra $10,000 on your sale price is worth roughly $280 to an agent on a 2.8% fee, but a sale that closes this week rather than next month is worth the entire fee, sooner. When an agent says “I’d take this offer,” ask: “If this were your house, would you take it?” A good agent will answer that question directly, and will sometimes say “no, I’d counter, but here’s the risk.”

The same conflict runs the other direction when an agent recommends a lender, inspector, or title company. Good advice names the relationship: “I’ve closed thirty loans with her and she hits her dates” is a reason. Hidden compensation is a violation; Mississippi law lists “receiving compensation from more than one (1) party in a transaction … without the knowledge of all parties for whom he or she acts” among the grounds for losing a license, and bars a salesperson from “accepting a commission or valuable consideration … from any person, except his or her employer who must be a licensed real estate broker.” (Miss. Code § 73-35-21(1)(e), (l)) Ask, and expect a plain answer.

Test four: does the agent know the edge of their expertise?

The disclosure form every Mississippi agent gives you includes this line: your agent “cannot give you legal or financial advice.” (MREC Working With a Real Estate Broker form) That is not a formality. Whether to hold title jointly, how a sale affects your taxes, whether a boundary dispute is a title problem, and whether you can afford the payment are questions for an attorney, a CPA, a title company, and a lender. Good agents say “that’s a question for your lawyer, and here is why it matters” and then help you get the answer. An agent who answers every question is giving you some answers they are not qualified to give.

NAR’s own guidance to agents makes the same point, advising that buyer agreements tell clients to “seek appropriate professional services from inspectors, lenders, attorneys, tax advisors and title agents, among others.” (NAR, Written Buyer Agreements 101)

Test five: does the advice hold up when you check it?

You can verify most real estate advice in under an hour.

• Pricing: pull the comparables yourself on any portal and see whether the agent’s list matches what actually closed, not what is currently listed. Active listings are asking prices; only closed sales are evidence.
• Market speed: compare the agent’s “homes are moving fast” to the data. Mississippi homes were going pending in about 36 days (Zillow); the state’s median days on market tracked by the St. Louis Fed is higher. (FRED, Median Days on Market: Mississippi) Your agent should be able to tell you your zip code’s number, not the national one.
• Concessions: if your agent tells you “nobody is giving concessions,” note that sellers gave concessions in 44.7% of U.S. sales in the three months ending August 2026, the highest August share since at least 2020. (Redfin) Local markets vary, but an agent should know yours.
• Track record: an agent’s advice is only as good as their results. Post #16 in this series covers how to check closings, list-to-sale ratios, and expired listings.

Why confident advice is not the same as good advice

The widest study of agent performance found “selling prices varied widely among real estate agents, with a large proportion of them producing undesirable results.” (UF Warrington on Cunningham, Gerardi and Shen, Federal Reserve Bank of Atlanta) The same researchers tested whether better negotiators explained the gap and “found little evidence of superior negotiation ability.” (UF Warrington) What that leaves is judgment: pricing, preparation, timing, and knowing when to push and when to accept. Judgment is exactly what you are testing with the five properties above, and it cannot be assessed by how sure the agent sounds.

Buyers rate their agents very highly after the fact: 89% were very satisfied with their agent’s honesty and integrity, but only 78% were very satisfied with negotiation skills, the lowest of nine qualities measured. (NAR 2025 Profile) Most clients never find out what a better-advised version of their transaction would have looked like. The tests above are how you find out before closing instead of never.
