The median sales price of a Waukesha County home in the fourth quarter of 2024 was $410,000, based on data from the 2,600 properties sold during that time. In 2024, the median tax bill for the county was $4,890, which is 1.2% of the median value of the homes that were taxed.
This is 1.1 times higher than the average effective property tax rate of 1.11% in the U.S. in 2023.
The analysis of Waukesha County real estate data showed homeowners in Oconomowoc Lake, Lac La Belle, and Elm Grove paid the highest rates.
The above article calculates the effective property tax rate for 2024 using estimated inflation values and 2020 tax data provided by the county. In some cases, the actual effective property tax rate may vary slightly.
The U.S. housing market has surged in recent years, with its total value approaching $50 trillion in 2024—nearly five times its value in 2000.
“The value of America’s housing market will likely cross the $50 trillion threshold in the next 12 months as there are not enough homes being listed to push prices down,” said Redfin Economics Research Lead Chen Zhao.
