78 Bay Drive offers a rare opportunity to own a turnkey Keys retreat that seamlessly blends peaceful oceanfront living with built-in income potential. The main-upper residence features two bedrooms and two bathrooms, with both the primary suite and main living area capturing sweeping, unobstructed ocean views. Expansive sightlines and direct access to multiple decks and inviting outdoor living spaces create a seamless indoor-outdoor experience, immersing you in the natural beauty and tranquility of the surrounding water. A standout feature of the property is the separate lower-level livingspace, complete with its own private entrance, newly installed kitchen, ocean views, and ample parking. Perfectly suited for hosting guests or generating income, this space presents an exceptional opportunity to offset the cost of ownership while maintaining privacy in the main residence above. Offering remarkable flexibility, the property can be enjoyed as a single-family home with generous total square footage, or configured as two distinct living spaces, allowing a new owner to tailor its use to their lifestyle or investment goals. The home has been extensively upgraded, including a new pool and spa, expanded decks and stairs, a brick driveway, hurricane impact windows and sliding doors, a 200-amp electrical service upgrade, and mini split AC systems for efficient, individualized climate control. Blending modern upgrades with versatile living and a breathtaking waterfront setting, 78 Bay Drive is a distinctive Lower Keys offering -- equally compelling as a private coastal sanctuary, an income-producing property, or a combination of both.
