I don't live in Florida but I have a good friend who does. My understanding is that the answer is "depends". Have you lived there for 5+ years or did you just move there. If the former, probably something like $1500/year, if the latter, something like $6-8k/year. The issue is, SAVE OUR HOMES limited the increase to 3%/year, but property values shot up in the past 36 months or so. Which means people can't move into a home of the same value because the taxes become insane, but are perfectly reasonably(not that any tax is, but I digress) if you lived there for a length of time.
It varies by County/City. However, "Real Life" figures for my area are as follows: $450K current value property taxes are about $2,500/year with homestead exemption and 5-10 years in same home..., $6,000/year if you just moved in. These are from the property appraisal website for my neighborhood.
Either way, Floridians (an Texan's) should realize how fortunate they are. My house is assessed at $465,000 in suburban NYC. My taxes are pushing $13,000 a year and of that amount, $8,000 is for the school tax even though I have never had a child in the public school system. On top of that, I pay a state income tax at the marginal rate of 8.875% and sales tax at something like 8.25%.
