How owner costs in Green Knoll 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	$2,983 (±$220)	$3,310 (±$260)	+11.0%	No measurable change after inflation
Median home value	$482,500 (±$19,986)	$597,100 (±$30,926)	+23.8%	No measurable change after inflation

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