The United States holds the title for having the most expensive homes globally. This is primarily due to a combination of factors including high demand in major cities, limited land availability, and a strong economy. According to a report by Knight Frank, the average price of a luxury home in the U.S. reached $4.3 million in 2021, significantly higher than the global average of $3.4 million. The top markets for expensive homes in the U.S. include New York City, San Francisco, Los Angeles, and Miami, where the high cost of living and the allure of these cities as global hubs contribute to the premium pricing. Additionally, the scarcity of land in these areas, coupled with robust economic growth and a strong real estate market, further drives up home prices.
