The selling bank doesn't care if you homestead it, but you should....
"Every person who owns and resides on real property in Florida on January 1 and makes the property his or her permanent residence is eligible to receive a homestead exemption up to $50,000.
The first $25,000 applies to all property taxes, including school district taxes. The additional exemption up to $25,000, applies to the assessed value between $50,000 and $75,000 and only to non-school taxes. "
