The only thing that scares me about newly-built neighborhoods is that back when it was all the rage, all sorts of people were getting loans to buy in those neighborhoods. As the subdivisions matured, not all homeowners were taking care of their property even with HOA. Some subdivisions became really crappy.
If you can afford to buy a house in a well-established, upscale neighborhood, that is the better way to go. You know that most likely those residents are planning retirement in their house. And older people generally take better care of their house.
