Hello,
We have a feature called ‘Neighborhoods’ that comes with the Location Manager addon which creates pages for each of those areas and provides a built in way to manage the neighborhoods and a field for selecting them in the address area.

We don’t recommend using custom fields for address information but, you can do it that way, if you want.
We also have an advanced search addon for filtering search results by any custom field.

The Custom Post Types addon allows you to build different post types, each with different custom fields.
You see, if you use the built in location manager fields for location, then, those locations are available to each Post Type, but, custom fields are only available for one post type, and have to be recreated for other post types.
