How old are your kids? I think it’s really wonderful to have neighborhood friends for kids under the age of 10. After that, kids become so particular in who their friends are, they aren’t necessarily going to be friends with the neighbors. So, think about how many years this will be important for.
We are in a neighborhood with several kids my kids play with, and although we want to move to a different neighborhood/house, we will stay until my kids are maybe 12, 10, and 7 so they have more time to spontaneously play. After that age I think it won’t be a big deal to live someplace more isolated.
