Grundstückswerte; Auskunft aus der Kaufpreissammlung

The offices of the expert committees receive all contracts in which someone undertakes to transfer ownership of a property for a fee, including by way of exchange, or to grant a heritable building right. These contracts are collected and evaluated with regard to the various circumstances influencing the value of a property.

The purchase price collection is generally not public and may only be viewed, including the documents sent, by the members of the expert committee and the employees of the office for the sole purpose of fulfilling their duties. Information will be provided upon request if a legitimate interest can be demonstrated. This applies, for example, to authorities, publicly appointed and sworn experts and certain certified experts who are involved in the valuation of properties. Information may only be provided if it is necessary for the purpose of the valuation. Property-related information (i.e. stating the parcel number) may only be provided subject to certain conditions; the names and addresses of the contracting parties may not be disclosed.

Finally, the expert committee determines the standard land values on the basis of the purchase price collection and publishes these in the standard land value collection (for more information, see "Standard land values; standard land value information" under "Related topics"). The expert committees also prepare expert reports on the value of developed and undeveloped properties upon request (for more information, see "Property values; determination" under "Related topics").
