I found a cheap aprtmnt in Sydney, NSW and I want to rent it. However my problems are that I don't know the owner and the owner is not in Au at the moment. So what documents of the owner should i know to make sure it's safe for me to rent that aprtmnt? Some of my friends said that maybe they are not the owner of the aprmnt. Can anybody help me ? I've got their scanned license via email.
