Property summary
AI-generated overview
This exceptional investment opportunity presents a 7,130-square-foot freestanding commercial warehouse in Marathon, Florida, situated directly on US Highway 1, offering excellent visibility and accessibility. Built in 1974 and extensively remodeled in 2018-2019, the property boasts a new hurricane-rated metal roof, updated HVAC systems, ADA-compliant bathrooms, and new LED lighting throughout. The interior and exterior have been freshly painted, and a new hurricane-proof loading dock door has been installed. The building is fully insulated and attractively landscaped. A long-term, nationally recognized tenant, Advanced Discount Auto Parts, has occupied the space since 1991 under an absolute NNN lease, significantly reducing owner responsibilities. The current lease runs until February 2032, with three additional five-year renewal options extending to 2047, featuring escalating monthly rent: $5,954 from March 2022 to February 2027
