Florida is a:

Deed of trust states use a trustee rather than a mortgage instrument, with the property deed held by the trustee until the loan is paid. Florida uses mortgages, not deeds of trust, making this option incorrect.

Title theory states convey legal title to the lender until the mortgage is paid. Florida does not follow this approach, as borrowers retain legal title while the lender only has a lien.

While Florida does use non-judicial foreclosure in certain circumstances, this is a procedural characteristic rather than a property theory classification. The question specifically asks about property theory, not foreclosure method.
