Knight Frank World Wealth Report
Prices rose by almost 13% across US cities last year, compared with just 2.5% across Europe, the report said. And worldwide, growth was even flatter, with global luxury property prices rising by just over 2% in 2014.
New York saw the highest jump, with luxury residential real estate prices rising 18.8% year over year. In 2013, Knight Frank found that $1 million could buy 40.2 square meters of property in Manhattan; a year later, that figure has shrunk to 34 square meters.
Monaco still has the most expensive luxury real estate overall, followed by Hong Kong and London.
