Sure! The city that is home to the world's most expensive residential property ever sold is Hong Kong.

In November 2017, a luxury property known as "The Peak" was sold for a record-breaking price of $360 million. This extravagant property is located in the prestigious Victoria Peak neighborhood, offering breathtaking panoramic views of Hong Kong's skyline and Victoria Harbour.

The Peak is a prime example of the high-end real estate market in Hong Kong, where properties command exorbitant prices due to limited land availability and strong demand from wealthy individuals and investors.

It's worth noting that Hong Kong has consistently ranked among the most expensive cities in the world for real estate. The combination of its status as a global financial hub, limited land supply, and high population density contributes to the skyrocketing property prices in the city.
