I met a man who sold his house in LA (two miles from one of the beaches, he said), moved to western Arkansas, bought a bigger house than he had in LA on 20-acres and small tractor with a brush hog and had money left over. He was a retired mail man, so his pension goes a lot farther here than out there.
This is what a lot of Californians are trying to do. It's what I'd like to do, if I could be sure of where I'd like to go. But I wouldn't get THAT much for my condo (it's small and it's not on a beach), and I don't have so much money that I wouldn't need to use some/most of the money made for another house elsewhere.
But, similarly to the man you referenced, my cousin owned two houses in Ventura, CA (not on the beach but definitely in a beach city), one of which he'd been renting out for years, and a bigger, newer, nicer one he'd been living in with his family the past few years. He sold the rental when he moved to Idaho, paying cash for the newer, bigger one he bought there, and then moving into it and renting out his big, newer, nicer house in Ventura for a year. He thought he'd hold on to that house so they'd have a place to come back to in case they wanted to return to California (most people, once you leave California, it's difficult, if not impossible, to come back, hence my tough decision that I need to be sure of). But, seeing that he and his family have liked it in Idaho, my cousin finally decided to not deal with renting/renters anymore and to sell the newer house in Ventura. He did, for $1.2 million, I think, and banked whatever he got out of it. I guess he figures he'd be fortunate enough to be able to move back to California, anyway, if he ever decided he wanted to do so, and unlike a lot of others, he probably could.
Suffice to say, the housing in California is so crazy that people haven't been able to NOT consider such money-driven moves, regardless of their own political leanings, or those of the people in the places to which they move. I have a neighbor who attended the same church I do who moved to Tennessee with the stated goal of "getting the money out of the house." He did, and bought a house with a barn/workshop and several acres, instead of the nice-but-postage-stamp-sized piece of property he had here that he sold for $990,000. Several other people I know from church have moved to Idaho, and a couple went to Texas. I suspect some of them do fit in where they went, beliefs-wise, and were obviously comfortable there, or they might not have stayed.
But that's not why they went. They went to cash in on financial opportunities.
