Long Island, ME
Long Island is a small island community in Casco Bay that separated from Portland in 1993 to form its own municipality. The island is accessible by Casco Bay Lines ferry and has a year-round population alongside seasonal residents. The housing stock is modest — cottages, small single-family homes, and a few larger properties.
For property professionals, Long Island is a very small island market where ferry access, limited infrastructure, and the seasonal population dynamic define every property consideration.
