Hope this helps with what you didn't understand.
Friends of mine have what they thought was their fully paid for property in Cyprus. It turns out that over 100,000 ex pats have property in Cyprus (Rep of Cyprus) and have no title deeds. Developers there are allowed to take out loans on land after you buy property that is going to be built on it, if you want title deeds and the developer has loans taken out, then goes bust, you have to pay his debts. A lot of problems also in Spain with property. I don't know anything about property purchasing in Serbia, nor do I want to in all honesty. I doubt, very very much if any Irish Bank, or any other Bank, will give you a loan based on Serbian property, or similar.
