    Overview

    This waterfront duplex includes two separate residences, each offering three bedrooms and two bathrooms. The property sits on a 7,500 square foot lot with approximately 75 feet of dock/sea wall, and features a fully fenced yard and an above-ground pool for outdoor entertaining. Ample parking is provided, and each unit has separate utilities, supporting independent living and rental practicality.

    Set along a deep water canal, the home is described as providing access to the ocean/bay with minimal time and is noted as well protected with Boot Key Harbor. The remarks also indicate the layout can be configured to face the canal with no bridges, offering a straightforward waterfront position for water-oriented use.

    For tenants, buyers, or operators, the property can be used as a classic live-in-and-rent arrangement by occupying one unit while renting the other. It may also be kept as a duplex income property, or converted to a single-family home facing the canal with no bridges, depending on the buyer’s plans. The remarks further state short-term rentals may be possible with the appropriate license, and the two-unit structure with separate utilities can be an advantage for households seeking flexible occupancy.
