Andre Barbosa is squatting in style.

The 23-year-old has moved into an empty $2.5 million mansion in a posh Boca Raton neighborhood, using an obscure Florida real estate law to stake his claim on the foreclosed waterside property.

The police can’t move him. No one saw him breaking into the 5-bedroom house, so it’s a civil matter. And representatives for the real owner, Bank of America, said they are aware of the situation and are following a legal process.

But the situation is driving his wealthy neighbors crazy.
