Venezuelan oil executive Alain J. Viergutz has listed his waterfront mansion in Key Biscayne for $19.8 million. The property was put on the market on January 6, just three days after U.S. Army Delta Force commandos captured Venezuelan President Nicolás Maduro and his wife, Cilia Flores, during a night raid in Caracas.
Viergutz is president of Grupo Centec, a company that provides services to the Venezuelan oil industry. He previously served as president of the Venezuelan Oil Chamber. According to property records, Viergutz purchased the 8,200-square-foot mansion at 100 Cape Florida Drive for $11 million in 2021. The home, built in 2007 on a 0.4-acre lot, features four bedrooms, four bathrooms, a half-bathroom, a pool, and a dock. Viergutz has been a Miami homeowner for many years and sold another Key Biscayne residence for $17.4 million in 2021.
Lucia Marin of One Sotheby’s International Realty is handling the listing. Mansion Global first reported the property coming to market.
The recent military operation in Caracas was orchestrated by the Trump administration on January 3. U.S. fighter jets and bombers targeted Venezuelan air defenses before Delta Force troops detained Maduro and Flores. “It is too soon to measure the full scale of the impact of the capture and Trump’s vague plans for the U.S. oversight of Venezuela,” according to the release.
Venezuelans represent an important group of homebuyers in Miami-Dade County, with Doral being home to one of the largest Venezuelan communities in the United States. After deportation protections were revoked for many Venezuelans last year under the Trump administration, Doral saw increased vacancies and rents dropped to their lowest level in three years.
Market observers suggest that more real estate listings connected to Venezuelan nationals may emerge following these events. However, appraiser Jonathan Miller noted in his Substack “Housing Notes” that “Maduro’s capture did little to rattle U.S. consumers and the housing market nationwide.”
