For more than 15 years, Sebastian Mobo has called the Hamptons home, giving him a deep appreciation for the communities, lifestyle, and relationships that make the East End unique. A Southampton-based real estate professional, Sebastian works with buyers, sellers, and renters throughout the Hamptons, bringing a service-first mindset, international perspective, and genuine commitment to helping clients make confident decisions.
That approach is deeply influenced by more than five years of professional caregiving—a role Sebastian continues alongside his work in real estate. Caring for others has strengthened his ability to listen closely, remain patient under pressure, anticipate individual needs, and understand the importance of trust. Combined with his broader background in customer service, those experiences have shaped a real estate practice centered on people rather than transactions.
Since entering real estate, Sebastian has closed numerous sales and rental transactions and has had the opportunity to learn alongside some of the Hamptons’ leading agents. His experience with Christie’s International Real Estate Group expanded both his professional network and his exposure to international clientele, including buyers from abroad looking to make the Hamptons their home. He has been recognized among the Top 10 East End agents for the month at a former brokerage and was named one of James Lane Post’s “Up-and-Coming Real Estate Agents to Know” in 2024, in addition to being featured in the publication’s Real Estate Confab.
Born in the Philippines and relocating to the United States in 2009, Sebastian brings a global perspective to his work. He is also co-owner of VS Condotel, a hospitality venture in the Philippines, which keeps him connected to property and hospitality beyond the Hamptons.
Outside of real estate, Sebastian has traveled to more than 30 countries and enjoys basketball, reading, working out, and staying involved in his community through weekly Bible study at Hamptons Christian Fellowship.
For Sebastian, great real estate service begins with listening. Whether a client is buying, selling, or renting, his goal is to understand what matters most, provide thoughtful and honest guidance, and remain focused on the best possible outcome. He believes lasting client relationships are built the same way all meaningful relationships are: through trust, consistency, honesty, and genuinely putting people first.

"My husband and I were looking for a rental this summer for a month. We happened upon Sebastian. What a find!! A broker who cares about his clients' needs. We live in New York City and couldn't get out to the Hamptons to view availability. Sebastian went to several houses and did a video showing so that we would have a choice and know what the houses were all about. Then he negotiate...
