The tax of record is $54,141 (2025). As an estimate only, Florida reassesses upon sale. At this list price of $18,900,000 and a Miami-Dade rate near 2.0%, the estimated annual obligation would be approximately $378,000 without a homestead exemption, or about $377,000 with it, as the exemption lowers the taxable value only for a primary residence.

These are preliminary estimates, not quotes. For precise verification, you must consult the Miami-Dade Property Appraiser and a qualified tax professional. To discuss this further, contact Christopher Lazaro, Key Biscayne Real Estate Expert.
