If you are looking for a property investment in Italy and/or in Puglia, new upcoming area of the South, the “heel” of Italy, please deal with licensed estate agents only. The role of Italian real estate agents is quite different from that British one.
In the UK everybody can set up an estate agency without any qualification or experience. Viceversa in Italy they must be professionally qualified, hold a licence to practise and have indemnity insurance. The agents operating without license are illegals.
On internet there are many unlicensed mediators, dealing with foreign buyers, selling properties and renting holiday home. Do not trust them! They promise lots of useful services but the real extra service they provide is to charge a commission up to 100% more than a licensed Italian agent, or, raise the market price of the property. Moreover if you take their advice you will not be covered by the legislation and the code of ethics which the legal agents must adhere to. If you are dealing with an agent ask for their registration roll number to the chamber of commerce and which professional association they are registered to. Remember buying property in Italy, legally, is safe as buying property in the UK, all you need is just to know the differences and follow the rules!
