If you live in a major city, it’s likely getting more expensive to live downtown. The prices for luxury apartments are soaring high, and these penthouses are quite attractive to wealthy international buyers.

They like to be in the center of town, and in the most prestigious neighborhoods. “Wealthy buyers want convenience,” Joanna Leverett, head of international new developments at Savills, told Wealth-X. “Flagship developments provide services and facilities such as spas, wellness and restaurants that you wouldn’t normally get in a house, all within walking distance to the city’s restaurants and culture instead of being out in the sticks.” Designed by the top architects and designers in the world, these are no maintenance, turnkey properties. Edward de Mallet Morgan, head of super prime international property at Knight Frank, says this type of apartment is easier on the rent and resale market. “More owners are renting out their properties where there is a good management, rental service or a concierge, as it is nice to have some income being generated to put towards annual running costs,” he said.
