How home values in Illiopolis Township 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 home value	$94,400 (±$6,168)	$138,300 (±$39,443)	+46.5%	No measurable change after inflation
Median owner cost with a mortgage	$1,092 (±$59)	$1,133 (±$214)	+3.8%	No measurable change after inflation
Median real estate taxes	$1,843 (±$300)	$2,259 (±$699)	+22.6%	No measurable change after inflation

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