Places full of single family houses with essentials being 30 minutes away don't tend to stay like that for long. They are great business opportunities for developers of supermarkets, malls and the like. You buy some cheap land, build some cheap commercial low-rises, and rake cash as the tenants come flooding in.
There's not a single home in Summerlin, NV that's more than a 10 minute drive from a large supermarket. Majority of the houses are less than 5 minutes drive.
Sorry, I misread. I was giving an example of "They are great business opportunities for developers of supermarkets, malls and the like.", not of an isolated neighborhood.
