Description

Awarded the Florida Keys Preservation Star, this meticulously restored single-family home offers an enchanting blend of historic Key West charm, modern luxury, and high-yield investment potential. Holding a coveted TRANSIENT LICENSE allowing profitable nightly rentals, this turnkey Old Town sanctuary sits just a half-block from world-famous Duval Street while enjoying a prime position near boutique shops, fine dining, and the Southernmost Point. Step inside through iconic yellow doors into a bright, sunny retreat defined by historic Dade County pine walls, gingerbread balustrade details, high soaring ceilings, and rich natural light. The main level flows into an open-concept living area and a sleek white kitchen equipped with stainless steel appliances, ample prep space, and an oversized island with seating for six--perfect for gathering family and friends. Designed for indoor-outdoor living, double sliders spill out to a well-appointed, covered lanai featuring a large outdoor TV and a rare air-conditioned half bath.

The interior layout offers total comfort and privacy for guests. The main floor houses two king-bedroom suites complete with walk-in showers, including one with direct access to the poolside sanctuary. Tucked upstairs for added seclusion, the third ensuite bedroom features a queen bed, vaulted ceilings, and sunny exposure. Completely renovated with impact windows, and dedicated off-street parking, this property is designed for effortless ownership. Whether retained as a high-performing vacation rental with proven revenue projections or enjoyed as a private island getaway, this home offers a rare chance to own a piece of Key West paradise.
