Many housing markets where home prices are highest are located in desirable coastal areas. These housing markets tend to have a lot of money, lack a major manufacturing builder, face significant zoning and building code constraints, and are hot spots for redevelopment. In the most expensive pockets of the country, the land is often more important than the property structure.

In particular, in the Western part of the country, where many analysts believe the housing shortage is worst, home prices have risen to levels above the national average over the past decade. This remarkable increase coincided with the technological development of the region, which had a significant impact on the income and wealth growth of the Western world.

Keep in mind that in states, there can be large variations in home values, especially between different school districts.
