How Do Real Estate Agents Price Homes?

Zillow reported an average Mississippi home value of $194,531 on September 30, 2026. That statewide figure gives context, but it cannot tell you what a particular home on your street is worth. (Zillow)

So how does an agent get from a house to a defensible asking price? I’ll walk through the comparative market analysis, or CMA: how agents choose comparable homes, adjust for differences, read current market activity, and weigh the cost of starting too high.

A CMA is a price range, not a promise

A comparative market analysis uses nearby sales and current listings to estimate a likely price range. Agents prepare one to help a seller set an asking price or help a buyer decide what to offer. (Redfin)

Redfin’s guide describes a CMA as “a decision-making tool that we use to help our buyers and sellers recognize key opportunities in today’s market.” (Redfin) The useful part is not the label or the page count. It is the evidence behind the recommendation, and whether the agent explains how that evidence applies to your home.

A CMA usually ends in a range, not a single magic number. The final list price is a decision within that range. It should account for the seller’s goals, competing listings, buyer demand, and how quickly similar homes are moving. A seller’s preferred proceeds are not evidence of market value. Redfin’s pricing guide warns that pricing around what a seller needs to take home can make a property sit longer, lose momentum, and sell for less than it was worth. (Redfin)

Choosing comparable homes

Start with homes buyers would actually consider alongside yours. Look for similar location, size, condition, layout, age, and features. Redfin describes a typical analysis of three to five recently sold homes, active listings, and pending sales. (Redfin) The number is a starting point, not a substitute for good matching.

Closed sales show what buyers have paid. Agents often focus on sales from the previous three to six months, and may extend the window when a slower market has too few recent transactions. (Chase) Redfin’s pricing guide also identifies the last three to six months as the preferred window. (Redfin) Older sales can still help, but a changing market may make them less relevant.

Active listings show the homes buyers can choose today. Pending listings offer a fresher, though incomplete, signal of what is attracting offers. Redfin’s pricing guide puts it this way: “Pricing a home requires not only analyzing recent sold data, but also considering pending and active listings to get live feedback from the market as it stands today...” (Redfin) Asking prices are not closed-sale prices, so an active listing is not proof that a home will sell for that amount. Expired listings can also matter. They show where the market did not respond to a previous price or presentation.

For Mississippi sellers, the local comparison matters more than a national headline. A house in one part of Central Mississippi may face different competing listings and buyer demand than a similar-looking house elsewhere. The best comp is not always the closest one on a map. It is the one that most closely matches what a buyer is comparing.

Adjusting for the differences

No two houses are identical. If a comparable has more living area, a renovated kitchen, a garage, or a different lot, the agent has to account for that difference. The adjustment is applied to the comp’s sale price to estimate what it might have sold for if it were more like the home being priced. Agents compare the adjusted indications rather than simply averaging raw sale prices. (Rocket Mortgage)

The adjustment should reflect what buyers in that market appear to value. It is not automatically the cost of installing a feature. A $20,000 renovation does not necessarily add $20,000 to a home’s market value. The agent should explain the reasoning and show how the adjustment connects to comparable sales. Fannie Mae guidance, as summarized by Colibri Real Estate, sets no specific net or gross adjustment limits. (Colibri Real Estate) That makes the explanation more important, not less.

Price per square foot can be a useful check, but it is not a valuation method by itself. It can mislead when the homes differ in condition, layout, property type, or features. A price that looks low per square foot may reflect a home that needs work, while a smaller, updated home may command more per square foot. The question is whether the homes are genuinely comparable, not whether one calculation produces a tidy average.

A CMA is not an appraisal

A CMA is an agent’s market-based opinion used to guide a listing or offer. An appraisal is a separate valuation product prepared by an appraiser, often for a lender’s use. The two may examine similar sales, but they are not interchangeable. A REALTOR’s opinion of value must state its basis, make clear that it is not an appraisal, and disclose whether the property was physically inspected, according to the NAR standard summarized by RealScout. (RealScout)

Appraisal guidance can still offer a useful reference point for a CMA. Colibri says Fannie Mae guidance for appraisals on loans sold to Fannie Mae calls for at least three closed comparable sales in the sales comparison approach, with comps generally closed within the last 12 months unless an exception is documented. (Colibri Real Estate) That does not mean every CMA needs to copy an appraisal report. It does mean the pricing logic should rest on actual closed sales, not one attractive example.

Online estimates can be a starting point, but they are not a substitute for seeing the home and checking the comps. RealScout reports that Zillow’s Zestimate has a median error of 1.83% for actively listed homes and 7.01% for off-market homes. (RealScout) Those figures are national measures, not a promise about the accuracy of an estimate for a specific Mississippi property. A broad automated estimate should not settle a specific home’s price.

Reading the market and the cost of overpricing

Absorption is the pace at which available homes are being taken up by buyers. A CMA should put the comps in that context. Ask what local inventory, pending activity, and time on market suggest about the pace of demand. Rocket Mortgage says agents reconcile adjusted comps into a price range while weighing market conditions such as absorption and whether the market favors buyers or sellers. (Rocket Mortgage) A national statistic cannot replace those local signals.

Mississippi’s statewide figures give context, not a pricing answer for your home. Zillow reported average Mississippi home values up 2.2% over the past year and said homes were going pending in around 36 days as of September 30, 2026. (Zillow) Those figures do not tell us how a particular neighborhood or property is performing. The local competition and recent comparable sales still have to do the work.

Overpricing can cost time and weaken a listing’s momentum. In an analysis of North Texas sales, the median seller started 3.1% above the eventual sale price, while the mean was 5.3%. (Clearfork Appraisals) In that same analysis, sellers who started 10% to 20% high cut the price with an 88% probability and had a median $16,000 gap between the first asking price and closing; those who started more than 25% high had a $35,000 median gap. (Clearfork Appraisals) These are North Texas results, not Mississippi forecasts. They are a warning about a pattern, not a promise about what any one seller will experience.

Early attention is useful feedback. Redfin’s pricing guide says, “The goal is a price that creates strong interest in the first week on market...” (Redfin) If showings and serious inquiries are scarce, the price may be part of the problem. Redfin recommends reassessing the price using current market data if a home gets little attention or few offers after a few weeks. (Redfin) A price reduction is not automatically a failure. Waiting too long to make a necessary correction can be more costly than responding to the market early.

The takeaway

Ask the agent to show you the closed sales, current competition, adjustments, and local market pace behind the recommendation. A price is only as useful as the evidence and reasoning that support it.
