Expiration of the lease is not among the stated legal grounds for eviction. If the tenant keeps paying the rent he or she cannot be evicted just because the lease has expired.
As for raising the rent, it cannot be done unilaterally without a lengthy administrative procedure. If the owner refuses to accept the rent, the tenant can deposit it at the nearest Banco Agricola.
I have a HUGE issue with a new apartment I moved into. I paid one month commission and two months deposit and the unit was shown to me at night and after moving in the noise is EXTREMELY LOUD ALL DAY with construction and workers yelling and laughing and car horns honking at all hours throughout the day. It is completely unbearable I want to move out and get my deposits back no person could remain sane and live here. Do I have any rights? It is so loud its unbelievable its hard to hear my wife talk its so loud.
