In the luxury real estate game, a listing agent hits the jackpot when the property they're representing becomes the world's most expensive, a title which can change at any moment. According to Yahoo Finance, that title belongs to the home at 17 Upper Phillimore Gardens in London's ritzy Kensington neighborhood.

Having been bought back in 2008 for USD $127 million by Olena Pinchuk, daughter of a former Ukranian president, the luxury property—which used to be a Victorian prep-school—is currently worth USD $1.58 billion. It has 10 bedrooms, an underground swimming pool (so you can get those laps in even while it's raining), a gym, sauna, theater, and a panic room (a feature anyone who lives in a place this pricey should definitely have).
