Ahh ohh, makes sense. I thought you were referring to the demonstrations with "libertarian's nightmare". And only with "landlord's nightmare" to my rental situation.

Yes, in Germany there are only very few valid reasons for temporary rental contracts. It's good for tenants but bad for the landlords. But living rent free sounds crazy 👀

If I owe the landlord a single cent more than the rent of a month, they have special rights to kick me out.

I don't know the details of your circumstances.  In New York City the government imposes all kinds of crazy restrictions on landlords, and if they are not met, tenants get to live rent free. Evictions are barred.   The free market is non existent.
