Investment Insights
Based on property information with market context.
This canal-front duplex offers two separate units in a block-built property with central HVAC. Each unit includes three bedrooms and two bathrooms, and each side has its own utilities. The exterior features include a fenced yard, deck and balcony areas, storm/security shutters, and an outdoor shower. A metal roof and ceramic tile flooring are in place, along with a cable-available service. An above-ground pool and entertaining-friendly outdoor space support full Florida living.
The property sits on a generous 7,500 square foot lot with 75 feet of dock/sea wall, providing canal access with minimal time and no bridges for deep-water routes. The canal location is described as very well protected with Boot Key Harbor.
Operationally, the property can be used as a duplex investment, live in one unit and rent the other, or—where permitted—consider short term rental options with the appropriate license. There is also an option described to convert the property into a single-family home facing the deep water canal.
