About Marianne Koke

Before embarking on a career in real estate, this agent earned a Bachelor’s degree in Psychology from Marist College and spent a year studying English Literature at Oxford University. Following her academic pursuits, she spent a summer in Austria as an Au Pair for Europe’s largest strawberry farmer. These diverse experiences have equipped her with a unique understanding of the various interpretations of “home,” enabling her to connect with clients from all walks of life.

For over thirty-five years, she has dedicated herself to serving the Smithtown, St. James, and Three Village areas as a committed real estate professional. Her extensive knowledge of the ever-evolving real estate market allows her to effectively guide both buyers and sellers through each step of the transaction process. She prioritizes meticulous attention to detail, ensuring that her clients are fully informed and comfortable from the initial open house to the final closing.

As a consistent top producer at Daniel Gale Sotheby’s International Realty, her success is rooted in her passion for the industry. She remains vigilant about current market trends and is deeply invested in securing the best possible outcomes for her clients—whether that means achieving the highest sale price for sellers or finding the perfect home for buyers.

Her clients appreciate her professionalism and strong work ethic, often returning for her services. Active in her community as a member of Sts. Philip and James parish and as a mother of four grown children, she possesses a profound understanding of the local area. She believes that a successful real estate agent must not only be knowledgeable about the market but also be actively engaged in the community they serve.

Suffolk County's real estate market represents one of New York's most dynamic and diverse property landscapes, stretching across Long Island's eastern expanse from bustling suburban communities to exclusive waterfront estates. With 9,107 total actively licensed agents serving the region, this market demonstrates remarkable depth and professional expertise, reflecting the county's complex mix of residential neighborhoods, commercial districts, and luxury coastal properties that attract buyers from across the metropolitan area.

The sheer scale of professional representation in Suffolk County reveals a market that operates at institutional levels, where every one of the 9,107 agents maintains email connectivity, enabling rapid communication and deal coordination across multiple price points and property types. This extensive network of licensed professionals supports everything from first-time homebuyer transactions in communities like Brentwood and Central Islip to multi-million dollar estate sales in the Hamptons, creating a sophisticated ecosystem that responds quickly to market shifts and seasonal demand patterns.

Major Suffolk County, New York Real Estate Markets

The county's real estate activity concentrates heavily around several key metropolitan areas, with Huntington, Babylon, and Islip serving as major commercial and residential hubs that drive significant transaction volume. These central markets feature diverse housing stock ranging from post-war suburban developments to newly constructed luxury communities, while coastal areas like Southampton, East Hampton, and Montauk command premium pricing due to their proximity to beaches and seasonal rental potential that attracts both permanent residents and investment buyers.

Emerging markets in communities such as Patchogue, Riverhead, and Greenport have experienced surprising growth as buyers seek more affordable alternatives to traditional high-end areas, creating opportunities for agents specializing in value-oriented transactions and redevelopment projects. The contrast between these developing markets and established luxury zones like Sag Harbor creates multiple distinct real estate ecosystems within the county, each requiring specialized knowledge and different marketing approaches.

Market Dynamics and Geographic Complexity

Suffolk County's real estate market operates with distinct seasonal patterns that significantly impact pricing and inventory levels, particularly in eastern coastal communities where summer demand can drive rental rates up by 300% compared to winter months. This seasonality creates unique challenges for agents who must navigate fluctuating buyer preferences, vacation home purchases, and the complex interplay between permanent resident sales and investment property transactions that define much of the county's higher-end market activity.

Geographic complexity adds another layer of market sophistication, as properties just miles apart can vary dramatically in value due to school district boundaries, flood zone designations, and proximity to transportation corridors like the Long Island Rail Road. Agents must possess hyperlocal expertise about everything from septic regulations in rural areas to co-op board requirements in more developed communities, making market knowledge extremely specialized and location-dependent.

Why Businesses Need Suffolk County, New York Agent Contact Data

Companies serving the real estate industry can leverage Suffolk County's comprehensive agent database to reach professionals handling transactions across dramatically different price points and property types, from affordable housing initiatives to luxury estate sales exceeding $10 million. This diversity creates opportunities for businesses offering everything from basic transaction management tools to sophisticated wealth management services, as agents require different solutions depending on their specific market segments and client demographics.

The complete email accessibility across all 9,107 licensed agents enables businesses to execute targeted marketing campaigns that can be customized by geographic area, specialization, or transaction volume, allowing for precise audience segmentation that maximizes response rates and conversion potential in this competitive and professional market environment.
