How home values in Hamilton Square 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	$302,900 (±$10,880)	$397,000 (±$20,064)	+31.1%	Up after inflation
Median owner cost with a mortgage	$2,303 (±$87)	$2,655 (±$108)	+15.3%	Down after inflation
Median real estate taxes	$7,607 (±$355)	$9,289 (±$307)	+22.1%	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.
