OFFERED IN A LUXURY AUCTION!Experience unparalleled luxury at 400 South Street, the true Southernmost private residence in the Continental United States. This iconic Key West estate, winter home to esteemed American artist, the late Seward Johnson and his wife, seamlessly blends timeless elegance with modern amenities. The expansive 4,008-square-foot concrete home, situated on a generous lot plus almost one acre of bay bottom, offers five bedrooms and five and a half bathrooms. Upon entering, the formal living room evokes the charm of the Hemingway era, leading to a sunlit Florida room with sliding glass doors that open to a vast outdoor oasis. The primary suite and two guest bedrooms are accessible via an elevator, each opening to a large balcony that provides panoramic views of the Atlantic Ocean. The property boasts a magnificent 50 x 20-foot pool and ample lounging areas, perfect for enjoying ocean breezes and observing local birdlife. With its unique location adjacent to the iconic Southernmost Point buoy and proximity to Key West's vibrant attractions, this estate offers an unparalleled living experience. Additionally, a coveted transient license allows for nightly rentals, presenting a prime investment opportunity or the option for a lavish private or corporate compound. Designated Multifamily (could accommodate up to 8 residential units) and located in the historic commercial tourist district, the possibilities are vast for a savvy investor. Part of the property needs complete renovation and the 1930 SF seawall requires partial restoration. THE Southernmost House is a rare gem in the United States! Due diligence package available upon bid registration.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
