Houses! What country has the WORST housing market in the EUROPEAN UNION?

I’m currently researching this topic and I would really like to see what country is doing the worst and the reasons why it’s sucking so bad.
This topic is really interesting (at least.. you know, to me) and your answers can help me with my research! Please and THANK you very much.

Feel free to answer this with any economy related ideas.

Spain… such an economically depressed country.. that’s my pick.
