Your best bet would be to check the local seacoast newspapers online, go to the seacoast real estate unfurnished apartments section, I saw over 200 apartments vacant all over the seacoast from Seabrook, NH right over the border from Mass all the way up to Kittery Point in Maine.

I checked cary and giampa but they seem to deal with property for sale it seems, I didn't see one rental on their site. May be if you drive up to the seacoast and go right in to one of these agencies, they'll bring you right to a few rentals to see if they interest you.
Like I said, the newspapers online should be your first way of getting a place. The site above that I mentioned, shows really good pictures of the apartments and all that. You just have to narrow it down and figure out exactly which town you're interested in moving to.
Good luck and keep us posted!
