Advocaat/Jurist gezocht: Mijn huisbaas wil mij uitzetten, terwijl haar opzegtermijn al is verstreken

Toelichting op de werkzaamheden:
My landlord is asking me and another 2 housemates to leave the premisses within 2 months, because she wants to sell the appartment. I am renting the room in the appartment since 31st of May 2020, and in the contract it is stated that after 1 year the rental agreement will continue for an undertemined period.

What are my rights in this situation, how this situation should be futher proceeded? I do not think I can find another accomodation within few months.

Is it legal to ask tenants to leave premises, just because owner wants to sell the appartment, or is there a law which defends tenants in these circumstances?
