Whenever people say this, my first response is: you should support building mixed use/mixed density.

You would have an easier time affording a single family home if there were a couple of duplexes, quad plexes, and low rise apartments around, with some small shops in the ground level.

Fewer people competing for the same single family homes and close access to bodegas and bistros. Easier time finding babysitters and dog walkers too.

We don't all have to love like Manhattan. Most of the nicest neighborhood in America are mixed density.
