Sweet single family home PLUS ADU! Simplicity meets modern comforts at 6 Pine Avenue in Old Orchard Beach! While the exterior offers an unassuming, classic coastal presence, stepping inside reveals a wonderful surprise of sleek, modern updates throughout and versatility of use galore. Originally built ca 1900, this sweet year-round bungalow underwent extensive renovations in 2024. The main level features a well-designed 3-bedroom, 2-bathroom (primary has en suite) airy layout with an open kitchen/dining/living area, a charming vintage entryway porch/mudroom, a dedicated laundry space, and stylish updated finishes. Downstairs, is a town-permitted 1-bedroom, 1-full bathroom ADU with its own updated kitchen, spacious living/dining area, and private ground-level entrance. The lower floor is also internally connected to the first floor, allowing the entire home to be used seamlessly as a single unified space if desired. The lower floor space offers endless occupancy possibilities: multi-generational living, space for larger groups living together comfortably, or generating reliable long-term rental income to offset your mortgage. Three bonus rooms downstairs provide flexibility for storage, home office, gym, craft room, creative studio, and more. The property also enjoys a rare detached 2-car garage situated on its own parcel across the street. Tucked away on a quiet residential street, yet close to town amenities and just a 7-minute walk to the beach, this is a deceptively spacious, turnkey home, immediately ready for enjoyment!
