The sad truth is that a cul-de-sac hoop is a massive and instant property value killer. Most, if not all, HOA rules in high priced neighborhoods prohibit them, and many prohibit front driveway hoops too.
Wouldn’t kids playing outside be good for property values? Was talking to a friend and he told me he’d never raise kids in his old suburb because he never sees kids playing outside. I assume it’s similar for most parents looking for a place to start their family in, seeing there are other kids in the neighborhood who your kid can socialize and be active with seems like a major selling point.
