Summary
On March 12, 2019 BORIS-D was launched as the first common land value portal of the federal states. This not only makes a significant contribution to the required nationwide property market transparency. With the realization and commissioning of BORIS-D, a significant step towards standardization has also been made. Originally conceived as a service with information about land values in a state-specific scope, the portal could have a great potential for further development against the background of the real estate tax reform.
