I recently did see this, perhaps linked from zillow, and was shocked/not shocked. California is the worst, but it’s the same typical blue urban areas/states, and the cause is usually high taxes.
When we moved to north florida several years ago, at about the pit of the housing collapse (especially bad in florida), no way we could have rented. It was only affordable to buy one of the sad foreclosures.
And those high taxes draw deadbeats from all over the country which increases the number of deadbeats sucking down the welfare. When they aren’t shooting each other.
Wait until they have to add 30,000 to all new homes for the solar panels. Nobody will be able to buy a home.
Don’t mistake coastal cities for all CA. I live in Sacramento, right in the middle of the list and about a quarter of rents in SF. Of course SF is a special situation. It’s about 49 square miles and every inch was built on long ago. No new housing without tearing old down. The rest of the Bay Area nearly as bad, because any unbuilt land is “green-belted” and can’t be built on. Here there’s plenty of room to build, at least in the surrounding burbs.
