How home values in Marathon 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	$425,200 (±$46,410)	$725,800 (±$58,769)	+70.7%	Up after inflation
Median owner cost with a mortgage	$2,502 (±$268)	$3,235 (±$476)	+29.3%	No measurable change after inflation
Median real estate taxes	$2,832 (±$213)	$3,995 (±$586)	+41.1%	No measurable change 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.
