OverSouth Realty: A New Era of Real Estate Begins in Long Island
By: TILRE Enterprises
SAYVILLE, NY — Local real estate leader Sean Manning has recently launched OverSouth, a forward-thinking real estate brokerage that is already gaining attention across Long Island. With deep historical roots and a modern approach, OverSouth is reimagining the traditional brokerage model and shaping a path forward for the future of real estate in New York.
The name “OverSouth” draws inspiration from the region’s early identity. “It’s what the area around Sayville and Bayport was once called—‘over the Great South Bay,’” says Manning. “We wanted something authentic that still sounded powerful and fresh.”
But the brand’s influence extends far beyond its name.
Agent-Centric. Innovation-Driven. Results-Focused.
OverSouth operates as a flexible brokerage, offering agents access to some of the industry’s leading tools, coaching, and support, without the outdated practices and bureaucratic hurdles that often limit professionals’ potential.
“We built a company where agents can expect to get back more than they invest,” says Manning. “A one-stop shop with every resource, cutting-edge tech, and a supportive team atmosphere.”
OverSouth is currently leading the charge in OneKey MLS for growth, excelling in both agent recruitment and transaction sides. With its headquarters in Sayville and branch offices in Saint James and Massapequa, the company is planning a fourth office opening in late 2025 or early 2026.
A Powerful Tech Advantage Paired with Exceptional Service
From AI-powered systems to an elite lead generation platform, OverSouth is working to modernize every aspect of the real estate process. The firm is also the only brokerage in OneKey MLS with a Zillow Flex license, which provides its agents with exclusive access to Zillow Showcase listings and a pipeline of high-quality buyers and sellers.
For clients, this translates to 24/7 dedicated service, expert negotiation, and a team that strives to deliver results in even the most competitive markets.
A Culture of Growth and Respect—Inside and Out
At its core, OverSouth is about people. Manning’s leadership style emphasizes authenticity, perseverance, and results, with no room for toxic culture or ego. “We’re building something special with people who love to work, love to grow, and treat others with respect,” he explains.
Many of OverSouth’s agents—including Manning himself—are first responders and community leaders. The company is highly involved in local chambers of commerce, youth sports sponsorships, and charitable events across Long Island.
What’s Next for OverSouth
With plans to expand into the South Fork and Nassau County’s North Shore, OverSouth is focused on steady growth while maintaining the personal touch and reputation it has worked to establish.
“In 3 to 5 years, I envision OverSouth as one of the leading forces in New York real estate. But it will always be a place where clients feel taken care of and agents feel valued,” says Manning.
“Real estate is about people before it’s about property. And when you get that right, the results tend to follow.”
