The initial expenses required to move in consist of a security deposit amounting to three months' rent, along with two months of rent paid in advance and the payment for the first month. The rental contract is open-ended, meaning it does not have a predetermined termination date. It concludes only when the tenant submits a notice of termination at least three months in advance. This notice period always starts on the first day of a month and must be observed accordingly. For private individuals, the minimum rental duration is two years, whereas companies are required to commit to a lease term of at least twelve months.
