I trust that was just a flippant statement...
Not at all. Moved from north to florida. 20k tax on 2000 sqft doesn't tell you a lot, if the assessed value of the home is million dollars.
On a percentage basis Florida property tax is on high side. Combine that with hurricane insurance (if you can get it) from a stable insurance company, it is pretty expensive. Also florida has home stead exemptions. So older folks who lived in the same house for long time pay meager taxes because of 3% yearly cap. But those rules doesn't apply if you are a new buyer.
