How home values in Groton 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	$1,873 (±$47)	$2,098 (±$107)	+12.0%	Down after inflation
Median real estate taxes	$4,372 (±$160)	$5,198 (±$368)	+18.9%	No measurable change after inflation

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