In Japan, it's common for the land to be worth a lot of money and the house on the land to be worth nothing. New buyers frequently tear down the house and build a new one. After a few decades of ownership, it is not unheard of for people to move out of their house, tear it down and replace it with a new one, and then move back in. I guess they rent a place to live while this is happening. In Japan particularly, this is a legacy of the poor quality of houses built in the early 20th century and the period after WWII when everything was slapped together as quickly as possible. They really were worthless after a decade or two because they were not built to last. This seriously damages the incentives for maintaining existing homes, because they are going to be worthless in 10 years, why bother?
