California housing market

In California, The Golden State, housing affordability is deemed a "crisis" by many.... On average, Californians spend the largest percentage (25%) of their incomes on housing of any state in the U.S. When looking at housing trends in California, it's important to keep in mind that local housing trends may be different than overall statewide trends because the state is so large (if California were a country, it would have the 5th largest economy in the world!). California overall and its largest metro areas (Los Angeles and the San Francisco Bay Area) have seen a continued rise in housing prices in recent years.
