I've lived in Jamaica Bay since 1997, first as seasonal resident, and then full time. It is a wonderful place to live. There are so many activities, there is something for everyone. As to sales people lying, they do. I would never buy a place without an inspection of the roof, floors, mold, etc. Just like I would never buy a used car unless it was checked by a mechanic. The people are friendly; you just have to start attending activities, shows, dinners, dances, etc. and you will make plenty of friends. I am very active in the community and wouldn't want to live anywhere else.
As to going further north, the weather is a lot worse (hotter in summer, colder in winter) and we have access to everything the Fort Myers area has to offer.
