Well, I have been going up Maine for summer vacations since I was born. The main problem with Maine is that most of it isn't online fully and lots of the people who live there year round are shall I say...challenged by the newest technology. Regardless, I assume the best way is to find a realtor in the town you wish to reside in and they might be able to help you out. If none exist to call in the town, they do have regional ones that cover large areas. The lack of quick communication between house owners is a downfall for going to rent a home for 12 months. As for apartments you should be able to find them online or at least get a phone number for them online.
