heat map of property prices

[practice_and_confidence]

Hi

I am interested in buying land for building my own house there and would like to know whether there is something like a heatmap of property prices of European countries, something like this of the German market:

immobilienbewertung.immobilienscout24.de/karten/]Mietpreise, Immobilienpreise, Immobilienbewertung in Deutschland

Would be really helpful if someone could point me in the right direction.

Thanks so much in advance
