In the Kaufpreissammlung (collection of purchase prices), data from and on notarized real estate purchase contracts is stored, where the properties concerned are located in the State of Berlin. It is maintained by the Gutachterausschuss für Grundstückswerte (Expert Committee for Property Values) in Berlin.
The data of the Kaufpreissammlung can, with careful observance of data protection, be made available on application for various purposes (e.g. individual-case information for certified real estate experts or statistical values for authorities and private individuals).
• Private individuals and institutions can receive block-related (anonymized, not property-specific) information from the Kaufpreissammlung on presentation of a legitimate interest.
• Real estate experts and staff of public authorities who frequently need data from the State of Berlin's Kaufpreissammlung can, in addition, apply for a separate online access to the Automatisierte Kaufpreissammlung (Automated Collection of Purchase Prices) "AKS Online". Information on access for repeated inquiries can be found under "Further information".
Further ways to obtain information from the Kaufpreissammlung can be found under "Further information".
