Warning for non-serious broker

In Turkey, there are several non-authorized agents, which are not always serious, because they are only looking to earn quick money. At restaurants, bars and hotels in principle, there you can hit all these "kind and friendly" people who want to help you to buy a "good and cheap" real estate by a friend or relative who is the broker. This can be a very expensive business for you, the risk that you buy "a pig in a poke" is usually large, these "friends" are only trying to earn quick money. Therefore, do your business only with a professional broker who you know and who you can trust.
