First of all you must be clear about your budget before looking at properties. This will keep you focused and save you from a lot of unnecessary trouble and wasted time. Secondly make a detailed research of the company and the agent you are dealing with, this will benefit you later in the process since trustworthy and experienced people will be necessary when dealing with investments abroad. Last, but not least, make sure you have understood all clauses in the contract before signing. Never sign a contract that is in a foreign language you are unable understand.
