RentsWatch is a service that gathers and visualises the rental prices across Europe in real-time. An interactive web app processes the gathered information, offering users chart cards and other data visualization and comparisons.

The data obtained can be used in many ways for web and TV reports on socially relevant issues such as housing, gentrification and rental prices. In the long term the result is a reliable source of live information for editors, which contributes permanently to secure the quality of journalism.
