I received a registered letter from my landlord, who is trying to sell her building, in which I hire an apartment. I have to leave my apartment before 2006.02.01. Meanwhile I have to show my apartment to potential buyers on wednesday and saturday during 90 minutes. The trouble is, my landlord couldn't sell her building on the official day of sale (2005.12.19), because none of potential buyers were interested. So I can't even ask the new landlord for a possible new lease, because there is no new landlord. The same happened to me two years back for the same reason, also during the Christmas/New Year period.
