Transaction data
Acquisition of transaction data for over 20 years.

For more than 20 years, we have been systematically compiling data on the real estate transactions published in Switzerland. In our transaction database, we collect more than 20,000 arm’s-length transactions every year in the owner-occupied sector and approximately 500 transactions from investment-property transactions. In addition, we provide data on nearly 20,000 new leases for rental apartments and 2000 contracts for office space annually.
