How home values in Knollwood have changed since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates

Median real estate taxes	$6,400 (±$458)	$7,098 (±$1,051)	+10.9%	No measurable change after inflation

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