You might be interested in doing a search for Mr & Mrs Oram on the internet. I don't remember the details but in short they bought a house in Northern Cyprus from a Turk. It turned out that he (the Turk) didn't have title to the land and had no right to sell it as it had been taken from a Greek Cypriot in the 1970s invasion. The Greek Cypriot has been trying to reclaim his land (and effectively the Oram's house) through the courts for years. As far as I know the Orams still don't know if they are going to lose the house and if the Greek Cypriot is going to get his land back.

I recommend that you do your research very carefully.
