Data on Real Estate Transactions is the tool for verifying the actual value of real estate through real buying and selling in a given area.
The Real Estate Transactions (RM Value) service provides access to detailed information on real estate transactions in Italy and allows properties to be analyzed based on various search parameters.

- by geographical coordinates using latitude and longitude
Results can be filtered by:
- property type
