just bear in mind that many so called written agreements are not worth the paper they are written on.As a foreigner you don,t have many rights if any .just prey that your landlord/landlady is a decent person and don,t get involved in any legal stuff here thats for sure .I would just ask for the one year to start with and tell them it might be on going after that.you will unlikely to get back any deposit so just take it in rent good luck.oh and take pictures of the whole place as to the condition of the house in case you get pulled for damages that you did,nt do.
