The law provides for a comprehensive rent review scheme, in addition to the annual indexation from the lease agreement. The landlord can apply this arrangement for rent increase, the tenant for rent reduction. The rent can be adjusted at the end of the agreed term of the lease or when at least 5 years have elapsed since the last rent adjustment.
The new rent is related to the average rent paid in the previous 5 years for comparable local premises. Experts give advice on this. If the parties cannot agree on the new rent, they can ask the court to establish a new rent.
In the rental agreement, the parties may deviate from this statutory regulation. The tenant and the landlord may also agree on an interim adjustment of the rent by mutual agreement.
