More than 221,000 Notices of Appraised Value are being mailed to Johnson County property owners, detailing changes in property values for this year. Interim County Appraiser Kara Endicott presented property revaluation trend updates to the Board of County Commissioners in a presentation on Thursday.

After two years of double-digit appraisal growth in 2022 and 2023, the real estate market returned to pre-COVID levels in 2024. The market in 2025 reflects a continuation of a stable real estate market trend.

Notably this year, the county experienced over $1 billion in new commercial construction. In previous years, that figure ranged from $368 million to $521 million.

“We are experiencing tremendous commercial growth in Johnson County,” said Mike Kelly, Chairman of the Johnson County Board of County Commissioners. “This historical economic investment is good for everyone. The more we can grow our tax base, through both commercial and residential development, the more we can spread out the property taxes necessary to fund our quality services.”

The increase in residential property across the county is around 6.5%.  Approximately 73% of residential property values that experienced an increase went up in value by 9% or less.

By state law, property is appraised at fair market value, as it exists on Jan. 1 of each year. Fair market value means the amount that a well-informed buyer is justified in paying and well-informed seller is justified in accepting in an open, competitive market.

To stay in compliance, the County Appraiser must appraise homes within 90-110% of sale prices in the county.

This year, the average value of a home in Johnson County is $508,000; the average selling price of new and existing homes in 2024 was $557,000.

“Appraised values are driven by sales prices. We know that a $508,000 home isn’t easily accessible for new college graduates, young families, retirees or first responders,” Kelly said. “If we want to lower the price of housing, we need to increase supply by building more units.”

The county also saw an increase in residential new construction permits for the first time since 2021.

“While the market overall remains stable, increases in property values and the average sale price demonstrate that residents and business continue to see Johnson County as a desirable place to live and work. The increase in building permits is also an emerging sign that the residential real estate market is beginning to regain confidence,” said Kara Endicott, Interim County Appraiser.

Homeowners will find on the back of their Notice of Appraised Value (NOAVs) information about the appeal process should they disagree with the appraised value. NOAVs can also be accessed online. The Appraiser’s Office has launched a appeals portal for property owners to file an online appeal. Learn more at the Appraiser’s Office website.

Parts of the county seeing higher increases include Spring Hill, Olathe, Lake Quivira and the southeast and northeast parts of the county.

This information was delivered along with the Interim County Appraiser’s slide presentation to the Board of County Commissioners on Thursday.
