In the State of Florida, the Homestead Exemption is a constitutional benefit of up to a $50,000 exemption removed from the assessed value of your property. It is granted to those who possess title to real property and are bona fide Florida residents living in the dwelling and making it their permanent home on January 1.
Trump would benefit somewhat from the homestead tax exemption, but when you're talking property in the millions, $50,000 is not a whole lot. He will benefit from no state income tax, no social security tax, no inheritance tax in the state of FL.
The Homestead Exemption has nothing to do with property seizure.
If I am understanding correctly, property can be seized IF it is connected to a crime. So perhaps they may seize property in NY but unable to seize his property in FL??
