A real, major industrial waterfront

Real retail and education anchors

The Maine Mall (Maine's largest shopping mall) and Southern Maine Community College (on the former Fort Preble site) anchor substantial local employment.

A real, distinctive airport asset

The Portland International Jetport is physically located within South Portland city limits, a real, disclosed asset most other Greater Portland Tier A markets do not carry directly.
