Dear Roxanne, to date I do not know of "one single agent", who can help you with the whole area. But I can stear you towards two ideas that may help. First: In central Italy there is an agent who speaks English. Not on the coast but in the central part of italy, he may know someone. You should also know that the agents of one agency work against the others and do not "share" information. they also do not represesnt you as they do in the US. Essentially they represent themselves.
In Rieti is a group called "Keys Partners. " One of their agents is Ricardo Diamilla and he speaks English... his email is diamilllariccardo86@gmail.com. Please use my name: Alfred Stites
The other idea is to go to gate-away.com and look in the provinces you want to live in along the coast. Specify an English speaking agent. Also please know that there are many reports of prices being elevated because you are American. Therefore I would recommend an intermediary who will look out for your interests and your interests only! I can recommend M. Grazia Colombo a RE Attorney who has successfully helped many Americans buy a home. Her email is mgrazia.colombo@leexe.it.
Again please use my name.
Good luck and great success. I hope you get to live your dream as we are here in Reiti.
Alfred "Chip" Stites, IL Correspondent.
