Since 2016, about 64,000 Californians have moved to Arizona each year. And when you look at the price differences, you can’t really blame them. California is almost 30% more expensive than Arizona across the board, and when it comes to housing prices, the difference is even more pronounced. A typical home in Los Angeles costs about $800,000 (and usually more), while a house in Phoenix will set you back about half that much: $410,000.
