How home values in Williams Bay have changed since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict

Median owner cost with a mortgage	$1,728 (±$134)	$2,042 (±$251)	+18.2%	No measurable change after inflation
Median real estate taxes	$4,033 (±$331)	$4,374 (±$647)	+8.5%	No measurable change after inflation

The Census Bureau publishes 2015–2019 dollars in 2019 dollars and 2020–2024 dollars in 2024 dollars.
