Sebastian Del Negro

Global Real Estate Advisor

Get To Know Me

Born in Argentina, Sebastian Del Negro played professional Rugby for several years, providing him a globe-trotting life. From his days as a professional athlete, he has lived in Australia, England, South Africa, Brazil, Peru, Paraguay, and Bolivia, to name a few. After an injury in his late 20s, Sebastian decided it was time to retire and eventually moved back to Argentina to work with his father. He earned an industrial degree with a master's in alternative fuels and took this knowledge and education to northern Texas, specializing in electric conversion kits. Fulfilling a growing interest in real estate, he obtained his real estate license in Texas in 2014. 

After buying a second home in the Florida Keys, Sebastian decided to move to this extraordinary island chain full time in 2019, along with his wife and two sons. A natural entrepreneur, Sebastian immersed himself into the Florida Keys real estate industry and has achieved much success with the ability to adapt to change quickly. He is fluent in English, Spanish, has his General Contractor license, enjoys fishing, being outdoors, and spending time with his family. He was previously with Coldwell Banker located in Key Largo. 

Seb (as he is known in the community) puts integrity and clients first, all while selling the Florida Keys way of life - work hard and play hard.
