SAYVILLE, NY — Sean Manning, a well-established figure in Long Island’s real estate scene, has launched OverSouth, a forward-thinking real estate brokerage that is quickly gaining attention across the region. By blending historical significance with a progressive mindset, OverSouth is reshaping the traditional brokerage model and positioning itself as a key player in New York’s evolving real estate market.
The name “OverSouth” is inspired by the area’s historical roots. “It refers to how the region around Sayville and Bayport was once known—‘over the Great South Bay,’” explains Manning. “We wanted a name that felt grounded in the local history, yet had a modern, fresh ring to it.”
However, the company’s influence reaches far beyond its name.
Empowering Agents Through Innovation and Flexibility
OverSouth offers agents a customized approach with access to industry-leading tools, expert coaching, and continuous support, all while eliminating outdated practices that can hinder growth.
“We’ve designed our company to ensure agents get more value than they invest,” says Manning. “It’s a complete platform that provides cutting-edge technology, valuable resources, and a collaborative team environment.”
Currently, OverSouth is seeing impressive growth in OneKey MLS, excelling in agent recruitment and overall transaction volume. The company operates out of Sayville with additional locations in Saint James and Massapequa and plans to open a fourth office by late 2025 or early 2026.
Innovating Real Estate with Technology and Service Excellence
OverSouth utilizes a range of modern technologies, from AI-driven systems to advanced lead-generation tools, to improve the real estate experience. It’s also the only brokerage in OneKey MLS with a Zillow Flex license, giving its agents exclusive access to Zillow Showcase listings and a consistent stream of high-quality leads.
For clients, this results in personalized, round-the-clock service, expert negotiation, and a team that works tirelessly to achieve the best outcomes, even in the most competitive markets.
Building a Culture of Integrity and Collaboration
At OverSouth, people come first. Manning’s leadership approach emphasizes authenticity, perseverance, and collaboration, creating an environment free from ego and negativity. “We’re focused on building something meaningful with individuals who enjoy their work, want to grow, and treat everyone with respect,” he says.
Many of OverSouth’s agents, including Manning himself, have backgrounds as first responders and community leaders. The company is actively engaged in local chambers of commerce, youth sports initiatives, and charitable events across Long Island.
Looking Toward Future Expansion
OverSouth has plans to expand further, with a focus on the South Fork and the North Shore of Nassau County. The company is committed to sustainable growth while staying true to the personalized service and strong reputation that it has cultivated.
“In the next few years, I see OverSouth becoming a leading force in New York real estate. But above all, it will continue to be a place where clients feel valued and agents are appreciated,” says Manning.
“Real estate is about connecting with people before it’s about the properties. When that connection is made, the results follow naturally.”
