I know Texas has very high real estate taxes, not sure about FL. Not surprising - I doubt Texas & Florida state gov’ts spend much less than average per capita and the tax revenue has to come from somewhere.
I think Texas also gets a lot of $ from taxes on oil income. I grew up in a small poor rural TX county yet our school bands provided free musical instruments to every student who joined. I was told at the time that we were a rich school district because of the tax base created by the oil wells in the county.
