Then again, maybe I won't - Judy Blume

Tony Miglione is thirteen, and his family lives in a cramped house in New Jersey. But then his Dad invents something that makes them rich, and they move to a luxury home in Long Island. But being rich brings it's own problems - Tony's Grandma feels useless when she doesn't have to cook any more, and his mum is obsessed with impressing the neighbours, but Tony knows the boy next door isn't as perfect as he looks. The only upside to his new life is that his neighbour Lisa keeps undressing with the light on. As he tries to adjust to his new life Tony starts to suffer from anxiety attacks and wishes everything would just be normal again.

Then Again, Maybe I Won't is a classic coming of age story from the boy's perspective, from Judy Blume, the author of Are You There, God? It's Me, Margaret.
