I've done some househunting in Italy. There are usually foreign firms - mostly UK- who specialize in helping English speakers with Italy property transactions. We worked with a company headed by Linda Travella, she might be able to help advise you or direct you.

Another thought is to check with a company who handles holiday rentals in the area - they might know of a property owner who wants to sell direct eliminating agent fees. This also eliminates some taxes if it's not new construction.

However if you don't speak Italian, it might be best to go thru a company like Linda's. The transaction is a bit complex and you will need assistance from someone who is looking out for you - the agent is actually working for the seller despite the fees you are paying.

Good luck, let us know what happens.
