How home values in Seneca 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	$287,900 (±$16,052)	$408,900 (±$55,681)	+42.0%	No measurable change after inflation
Median owner cost with a mortgage	$2,920 (±$543)	$2,894 (±$239)	−0.9%	No measurable change after inflation
Median real estate taxes	$8,587 (±$659)	$9,169 (±$1,087)	+6.8%	Down after inflation

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

Prices (the CPI-U, US Bureau of Labor Statistics) rose 22.7% between 2019 and 2024, so a dollar figure’s verdict compares the two after raising the earlier one by that much, using the Census Bureau’s test for a difference.

The two periods do not overlap, as the Census Bureau recommends for 5-year estimates.
