How property taxes in Big Pine Key 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 real estate taxes	$2,389 (±$261)	$3,398 (±$446)	+42.2%	No measurable change after inflation
Median home value	$363,700 (±$18,778)	$637,000 (±$53,923)	+75.1%	Up after inflation
Median owner cost with a mortgage	$2,122 (±$146)	$3,028 (±$268)	+42.7%	Up after inflation

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