How home values in Grafton 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	$234,800 (±$9,100)	$328,800 (±$13,054)	+40.0%	Up after inflation
Median owner cost with a mortgage	$1,643 (±$91)	$2,050 (±$105)	+24.8%	No measurable change after inflation
Median real estate taxes	$3,913 (±$136)	$4,360 (±$304)	+11.4%	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.
