The 15 most expensive houses in the world and who own them (With Pictures)

3. Penthouse at Tour de Odeon, Monaco – $400 million

Monaco, like Dubai and Abu Dhabi, is known for its extreme, sun-soaked luxury. The penthouse at the Tour de Odeon there has been called the most expensive apartment in the world.

It’s in the second tallest building on the Mediterranean skyline, and it has fun hookups like a 360° view of the water, and access to a rooftop infinity pool with a waterslide that goes into it. Plus, the apartment is in Monaco, a tax haven that attracts high-rollers, so life in general is pretty glitzy.
