Guys, thank you on your guiding lines on this subject.
I read the links you provided me, and I got somehow ... amazed about how thinks are going on this
First: It is not wise to buy a piece of land that already has 2-3 owners )
Second: Too many problems pointed by too many people in that region regarding the land proprieties in North Cyprus.
Third: Some personal bad experience with people over there in one trip I did this summer in North Cyprus (I'll give details on this experience in another post on other subject).
Conclusion: I advised my brother in low to quit this option to buy some land in North Cyprus. He agreed. He is looking now into Lemesos area, where at least the risks are almost zero.
And finally ... what I do not understand: how someone can sell you a piece of land that is not his property?
