SAYVILLE, NY — At a time when many real estate firms are scaling back, OverSouth Realty, founded by local industry expert Sean Manning, is scaling up—and fast. With a fresh, no-nonsense approach and deep roots in Long Island’s history, OverSouth is quickly becoming one of the region’s most talked-about brokerages.
The firm’s name, OverSouth, is a nod to the area’s original colonial nickname referencing the region “over the Great South Bay.” But what’s happening at OverSouth today is anything but historical.
“We’re not just another brokerage,” says Manning. “We’re creating an environment where innovation, results, and agent empowerment drive everything we do.”
A Ground-Up Reinvention of the Brokerage Model
At the heart of OverSouth’s success is a business model built for the modern real estate professional. The company is structured as a true a la carte platform, giving agents access to industry-leading resources, technology, and support—without forcing them into outdated systems or rigid structures.
Within its first year, OverSouth has already ranked as the fastest-growing brokerage in the OneKey MLS, leading in both agent acquisition and deal production. With its flagship office in Sayville and additional locations in Saint James and Massapequa, a fourth office is already in the pipeline for early 2026.
Where Technology, Trust, and Tenacity Meet
OverSouth isn’t just innovating for agents—it’s also revolutionizing the client experience. With tools like AI-powered lead generation, real-time CRM systems, and an exclusive Zillow Flex license (the only one in OneKey MLS), the company ensures both agents and clients are operating at peak advantage.
“We’ve built a system that gives our clients a serious edge—especially in competitive situations like bidding wars or off-market deals,” says Manning.
Clients also benefit from white-glove service and 24/7 responsiveness, while agents enjoy a business model that actually supports growth and work-life balance.
Culture-First, Community-Driven
OverSouth’s rapid growth hasn’t compromised its values. The company actively supports local chambers of commerce, sponsors youth sports, and backs community-focused initiatives throughout Suffolk and Nassau Counties.
“We’re made up of first responders, top producers, and real people who genuinely care,” Manning says. “Our culture is built on positivity, respect, and leading by example.”
The team looks for like-minded agents who bring energy, empathy, and ambition—without the ego. “We don’t just want people who can sell. We want people who other people want to be around,” he adds.
The Road Ahead
With expansion plans targeting the South Fork and North Shore of Nassau, Manning envisions OverSouth becoming a dominant force in Long Island and NYC real estate over the next five years—without sacrificing its personalized, high-touch approach.
“At the end of the day, this business isn’t about volume—it’s about value,” Manning says. “Value to the client, to the community, and to the people you work beside every day.”
