Platte County, MO Real Estate Market: July 2026 Update
By Joe Nelson, Retired Air Force, Nelson Home Group Team Leader and Mortgage Loan Originator
The Platte County, Missouri real estate market is the appreciation leader among the Kansas City metro’s seven most populous counties. The July 2026 median sales price hit $425,000, up 9.3% from a year ago, and the year-to-date median is up 9.0%, so this is a trend, not a one-month spike. The tradeoff: homes took 54 days to go under contract, the longest of any large county in the metro.
This is the Platte County companion to the August 2026 Kansas City market update.

Source note: Heartland MLS Local Market Update, Platte County, MO, July 2026, all property types combined.
Closings jumped 25.6% to 167 homes, the average sale crossed half a million dollars, and supply tightened to 2.7 months. Against the metro’s 3.9% appreciation, Platte County is running at more than double the pace.
Why are Platte County home prices rising faster than the rest of the metro?
The year-to-date median of $424,999 is up 9.0%, which is why July reads as a trend rather than a spike.
Part of it is genuine appreciation and part is what is selling. The year-to-date median of $424,999, up 9.0%, says the price level itself has climbed all year, and the 11.7% jump in average price says the county’s mix keeps tilting toward newer and larger homes, including new construction in the Highway 152 corridor and the airport’s growing employment pull. When a county’s median and its year-to-date median agree this closely, the appreciation is real. The June 2026 Platte County market update showed average prices already up more than 11%, so July confirmed the trend rather than starting it.
For scale, the runner-up among the large counties was Johnson County, Kansas at 5.3%, and Jackson County came in at 4.2%. A few small outlying counties posted bigger percentage swings in July, but on a few dozen sales each, which is sample noise rather than a trend.
Why are Platte County homes taking 54 days to sell?
Higher price points draw from smaller buyer pools, and Platte County now carries the second-highest median in the metro behind Johnson County. Fifty-four days against the metro’s 36 is not weakness; it is physics. Fewer households shop at $425,000 than at $300,000, and a smaller county of 167 monthly sales swings harder on a handful of slow listings. But the number carries a lesson for sellers: in the metro’s fastest-appreciating large county, the market still takes its time, and an overpriced listing at this price point sits longest of all.
What does this mean if you are buying or selling in Platte County?
Cass and Leavenworth counties were the next slowest large counties at 45 days each.
Sellers: you own the metro’s best large-county appreciation story, and the way to cash it in is patience plus precision, an accurate day-one price and a marketing plan built for a 45-to-60-day window rather than a weekend blitz. Buyers: the longer clock is your opening. With homes sitting nearly eight weeks and pendings down slightly, Platte County gives you more time to inspect, negotiate, and structure an offer than Clay County’s 29-day sprint next door.
One more thing worth understanding before you read the 2.7 months of supply as loose: supply and inventory are not the same number, and I broke down the difference between housing inventory and months of supply in a companion post this week. Platte County’s inventory fell 4.8% while supply fell 12.9%, because the pace of closings picked up at the same time the shelf got shorter. And if you are reading national headlines about falling prices, I answered whether Kansas City home prices will drop using the same July data. Platte County sits at the slow end of that range and the Wyandotte County update, at 26 days, sits at the fast end; my breakdown of how long it takes to sell a house in Kansas City explains the spread.
Leavenworth County rounds out the July county reports: July sales rose 12.8% and year-to-date closings are running at roughly double the metro pace. Read the Leavenworth County July 2026 update.

Is Platte County the fastest-appreciating county in Kansas City?
Among the metro’s seven most populous counties in July 2026, yes. Platte County’s 9.3% year-over-year median increase led that group, with Johnson County, Kansas next at 5.3%, and its 9.0% year-to-date increase confirms the trend is sustained rather than a single-month sales-mix effect. The metro as a whole appreciated 3.9% over the same period.

Why do homes take longer to sell in Platte County?
Platte County homes averaged 54 days on market in July 2026, against a metro average of 36, because higher-priced homes draw from smaller buyer pools. The county’s median is the second highest in the metro, and with 167 sales in July, a small number of slow listings moves the average noticeably.
Is Platte County a seller’s market in 2026?
Yes. Supply fell 12.9% to 2.7 months in July 2026, below the three-month threshold that defines a seller’s market, and closings rose 25.6%. Sellers hold the pricing advantage, but the 54-day average time to contract means they should plan for a longer marketing window than sellers elsewhere in the metro.
