This is always best avoided by choosing carefully who you take advice form. This is not normally found in bars and restaurants or Hotel lobby´s! At times it might appear that anyone who has ever spent a week on holiday here is suddenly a property expert! It is best to use the services of a reputable Real Estate Company and take advice from a Lawyer. The Lawyer is bound to look after your best interests and will always advise if he feels that there are reasons why you should not go ahead with a particular property. This kind of situation is very rare but it is always best to have it covered.
