Two trackers looked at the exact same streets in Mission Hills this year and came back with opposite stories. Redfin's data, covering the three months ending in June 2026, put the neighborhood's median sale price at $1.3 million, down almost 24 percent from the same stretch a year earlier. Zillow's home value index, updated at the end of July 2026, put the typical Mission Hills home at $1.7 million, up 10.5 percent over the same twelve months. Same zip code. Same several months. One line going down, one line going up.
Neither number is wrong. They're measuring different things, and the gap between them is the most useful piece of information a buyer or seller can have about this stretch of Kansas City, from Waldo up through Brookside and West Plaza on the Missouri side, across the state line into Westwood, Fairway, Prairie Village, and Mission Hills. The single median you see on a portal search is rarely the whole market. It's whichever handful of homes happened to close that quarter, and in several of these neighborhoods, that handful is small enough for one unusual sale to swing the number by six figures.
Why Two Trackers Can Disagree About The Same Streets
A median sale price counts only what actually changed hands in a given window. A home value index like Zillow's is a model, recalculated across the full stock of homes whether they sold or not. When a neighborhood has plenty of transactions, those two measures tend to stay close together. When it doesn't, they drift apart, sometimes in opposite directions.
Mission Hills is a case study in why. Only 10 homes sold there in June 2026, down from 21 in June 2025. That's a small enough sample that a single high-end estate sale, or a single dated ranch that needed everything redone, can move the median by hundreds of thousands of dollars without the neighborhood actually repricing. That's how the same neighborhood can show a sale price of $1.3 million and a modeled value of $1.7 million within the same few months. Both numbers are accurate. They're just not answering the same question.
Fairway shows the same pattern at a smaller scale. In March 2026, its reported median sale price fell 45 percent year over year to $615,000. That's not a market correction. Only seven homes sold in Fairway that month, up from five the year before. Two or three differently priced homes closing in a low-volume month is enough to produce a headline-looking swing that has nothing to do with what buyers are actually willing to pay.
What The Corridor Actually Looks Like Right Now
| Neighborhood | Side of the line | Recent median sale price | Typical value estimate | What it suggests |
|---|---|---|---|---|
| West Plaza | MO | -- | around $265,000 | The most affordable entry point directly against the Plaza itself |
| Waldo | MO | $293,000-$315,000 (Jun-Sep 2026) | -- | High sales volume keeps the number relatively steady month to month |
| Brookside, citywide | MO | around $380,000 (early 2026) | -- | Spans $220,000 starter bungalows to $850,000-plus renovations |
| Brookside Park (a named pocket within Brookside) | MO | $847,000 (3 months ending May 2026) | -- | One street-level pocket now selling for more than double the broader Brookside median |
| Westwood | KS | $453,000 (3 months ending Apr 2026) | $438,325 (Mar 2026) | Sale price and modeled value nearly match, a sign of a more uniform market |
| Prairie Village | KS | $554,000-$585,000 (Mar 2026) | $425,791 | A $130,000-$160,000 gap points to a market split between original and rebuilt stock |
| Fairway | KS | $615,000 (Mar 2026, only 7 sales) | around $634,000 | Thin monthly volume means large swings that don't reflect real repricing |
| Mission Hills | KS | $1.3 million (3 months ending Jun 2026) | $1.7 million (Jul 2026) | Fully built out with almost no new construction, so a single sale can move the median |
Read across that table and the story isn't a smooth price gradient from Waldo to Mission Hills. It's a set of markets with very different amounts of turnover, and turnover, not just location, is what decides whether you should trust the number you see.
The Gap Is A Renovation Story, Not Just A Location Story
Look at the difference between Prairie Village and Westwood. Westwood's recent median sale price of $453,000 sits close to its modeled typical value of $438,325, a gap of roughly $15,000. That's a market where the sale prices and the underlying stock largely agree with each other. Prairie Village tells a different story. Its recent median sale price of $554,000 to $585,000 sits $130,000 to $160,000 above the modeled typical value of $425,791.
That gap is what a renovation-driven bifurcation looks like in the data. Prairie Village has a wide range of housing stock, from homes largely untouched since the 1950s and 60s to properties that have been rebuilt from the studs, and the homes actually closing right now skew toward the rebuilt end. The modeled typical value, which accounts for the entire stock including homes that aren't currently for sale, pulls the average down. A buyer who sees "$425,000 typical value" and expects to find that home on the market this month is going to be surprised by what's actually available and what it's asking.
Brookside makes the same point at the neighborhood-naming level. The broader Brookside market carries a median around $380,000, a figure that reflects everything from $220,000 entry-level homes to $850,000-plus premium renovations. But Brookside Park, a specific named pocket within that larger area, posted a median sale price of $847,000 over the three months ending in May 2026, up 46.8 percent year over year, with price per square foot up 33.3 percent over the same period. Search "Brookside" and you'll get one number. Search the specific pocket and you'll get a completely different market.
The State Line Adds A Second Variable
Crossing from Missouri into Johnson County changes more than the sticker price. A $400,000 home in Overland Park typically carries somewhere between $4,200 and $5,500 a year in property tax, and comparable homes on the Missouri side generally run somewhat higher for the same value. That means the lower list prices you'll find in Waldo or West Plaza don't automatically translate into lower monthly carrying costs once tax is added to the comparison, and the higher list prices in Prairie Village or Fairway don't automatically cost as much more as the sticker suggests. Neither side of the line is simply cheaper. The full comparison has to include what the county bills you every year, not just what you pay at closing.
Questions Worth Asking Before You Anchor On A Median
- How many homes actually sold in that neighborhood last month? A median built on 40 sales means something different than one built on 7.
- Is the number you're looking at a sale price or a modeled typical value? They answer different questions.
- If there's a gap between the two, is it renovation-driven? A wide gap usually means the neighborhood has two markets, not one.
- What does the property tax bill look like on each side of the state line for a home at this price point?
- Does the specific pocket or subdivision inside the neighborhood have its own track record, separate from the broader area name?
None of these questions have a universal answer. They have a local one, street by street, and that's the work worth doing before you set a number in your head.
FAQ
Is it cheaper to buy in Missouri or Kansas along this corridor? Neither side is consistently cheaper once you account for the full picture. Missouri-side neighborhoods like Waldo and West Plaza generally show lower list and sale prices, but Johnson County's property tax load tends to run somewhat lower for a comparable home value. The right comparison weighs purchase price and annual carrying cost together, not the sticker price alone.
How many sales does it take before a neighborhood's median price means something? There's no fixed number, but treat any median built on fewer than a handful of sales in a given month as a range rather than a target. Fairway's 45 percent monthly swing came from a shift of just two sales, from five to seven. Waldo, which regularly sees 40 or more sales a month, produces a far steadier number by comparison.
