To add more context: Many people inherit flats since most of apartments are owned, therefore your grannies and uncles are all proud owners. If there's nothing to inherit, you're screwed. People do rent, but since apartments are all individually owned, you need to rent from single apartment owner at market price and cater to your landlord individual quirks. Many of those buildings are near their official expiry date and it's kind non-obvious what happens when they begin to crumble.
