Mansions Destroyed investigates what happens when the most expensive homes in America meet the ocean.

$10 million condos that flood on a sunny day. Island towns whose only road out washes away. Beach houses falling into the Atlantic while the state argues over who pays. Each episode takes one real place, Key West, Hatteras, Malibu, Miami Beach, and follows the water, the money and the decisions that left it exposed.

Every number comes from public records: county budgets, FEMA flood data, state permits, court filings and federal reports. Real places, real prices, no speculation.

New episodes every week on coastal real estate, flooding, erosion, insurance, seawalls and the towns deciding whether to fight the sea or retreat from it.
