How home values in Island Grove 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 real estate taxes	$2,546 (±$370)	$3,945 (±$569)	+54.9%	Up after inflation

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