It means that if you have a vacant house or apartment (because you’re trying to sell it or rent it or you have a second home for vacation (beach house, ski chalet, etc)) you will be FORCED to rent it. At whatever the government tells you is a ‘fair price’. Or even turn it over altogether.
I got wind of this a few days ago and told my husband. He was incredulous. Don’t they have rule of law re: personal property, or is it all just public domain?
