The most expensive cities in the U.S. are usually costly for a good reason — several, really. Residents are willing to pay extra for everything from housing to food to gas if it allows them to live in a place with a wealth of employment opportunities or great weather. Others are looking for cosmopolitan living, with a host of restaurants, museums and other cultural options on tap. Many of these expensive cities appear in our ranking of the most expensive housing markets in the U.S.
However, in some cases, simple isolation plays a leading role in high prices. When pretty much everything has to be imported over long supply lines, prices are bound to be higher.
