The advantage is for high income people, of course. If you make alot of money (or have alot of retirement income coming in) florida kicks ass.
As a simple example:
If you make 1 million a year and live in a 2 million dollar house.
Property tax in Cali : 20k Income tax in Cali : ~65k
Property tax in FL : 40k Income tax in FL: Zero
So in this example, you are 100% better off being in florida.
