Rent Index for Residential Rentals
The rent index provides information on the locally customary comparative rent in accordance with Section 558d of the German Civil Code (BGB). This reflects the rents typically paid for various types of apartments that are comparable in terms of type, size, amenities, condition (including energy efficiency), and location.
Current Note
The 2023 rental index has been updated using the consumer price index for net base rents in Thuringia and has been available for reference as a simplified rental index since September 7, 2026.
