Venezuelan oil executive Alain J. Viergutz has listed his waterfront mansion in Key Biscayne for $19.8 million, following the recent capture of Venezuelan President Nicolás Maduro and his wife by U.S. Army Delta Force commandos.
The property, located at 100 Cape Florida Drive, was put on the market on January 6 through One Sotheby’s International Realty agent Lucia Marin, according to Redfin data. The listing was first reported by Mansion Global.
Viergutz serves as president of Grupo Centec, a company providing services to Venezuela’s oil sector. He previously led the Venezuelan Oil Chamber, based on published accounts.
Records show Viergutz purchased the 8,200-square-foot mansion for $11 million in 2021. Built in 2007 on a 0.4-acre lot, the home features four bedrooms, four bathrooms, a half-bathroom, a pool, and a dock. Viergutz is an established homeowner in Miami; he sold another residence in Key Biscayne for $17.4 million in 2021.
On January 3, during an operation organized by the Trump administration in Caracas, U.S. forces detained Maduro and Cilia Flores after airstrikes targeted Venezuelan air defenses prior to their capture. This event has caused shifts in international relations.
The broader impact of Maduro’s detention and potential changes to U.S.-Venezuela policy remains uncertain.
Miami-Dade County continues to attract many Venezuelan buyers and is home to one of the largest Venezuelan communities in Doral. After deportation protections were revoked for many Venezuelans last year under the Trump administration, rental vacancies increased and rents reached their lowest levels in three years.
There may be more real estate listings connected to Venezuela’s political situation moving forward. However, appraiser Jonathan Miller noted on his Substack “Housing Notes” that “Maduro’s capture did little to rattle U.S. consumers and the housing market nationwide.”
