About John Demay

**Meet John**

John is a dedicated real estate professional with deep roots in Michigan. Born in Lansing and raised in Marquette after his family’s move in 1983, he graduated from Marquette Senior High School in 1999. He furthered his education at Northern Michigan University, earning a Bachelor of Science degree in 2004. John's background in law enforcement and security has instilled in him a strong commitment to integrity, ethics, and exceptional service.

Transitioning to real estate, John obtained his license and joined the Elder Agency in Marquette in May 2007. His career expanded in February 2008 when he earned his Insurance License, enabling him to offer both commercial and residential insurance services alongside his real estate expertise. This dual focus enriched his understanding of the insurance implications involved in real estate transactions. In 2011, John furthered his professional development by acquiring his Michigan Associate Broker’s License, which allowed him to broaden his services to include property management.

In 2014, John established PROEX Realty, where he emphasizes building a sustainable real estate brand, managing a streamlined property management company, and leading a technology-driven real estate team. In 2018, he joined eXp Realty, leveraging advanced technologies and resources to enhance the client experience.

John has also served as a Lieutenant Firefighter/EMT with the Marquette Township Fire Department. While he now prioritizes his family and growing business, he remains actively involved in various organizations. His past roles include President of Business Networking International (BNI), Chairman of the Presque Isle Advisory Committee for the City of Marquette, and Director and Volunteer for Big Brothers Big Sisters. Currently, he serves as treasurer of the Marquette County Flying Club and is a member of EAA Chapter 850, where he volunteers as a Young Eagles pilot.

Outside of real estate, John enjoys the great outdoors, spending quality time with his family on their boat exploring Lake Superior and the beautiful Upper Peninsula. As a private pilot, he combines his passion for aviation with his real estate career, enhancing his ability to connect with clients and properties. An avid hunter and fisherman, he embraces every opportunity to enjoy Michigan’s natural beauty.

John is committed to staying at the forefront of technology in the real estate industry, continuously researching and implementing new tools to provide an exceptional experience for his clients. He prides himself on offering straightforward, sound advice tailored to meet the unique needs of each client, without pressure.

He resides in Marquette, Michigan, with his wife, son, and two daughters.

Marquette County, Michigan represents one of the Upper Peninsula's most dynamic real estate markets, characterized by its unique blend of university town energy, outdoor recreation appeal, and natural resource heritage. Anchored by the city of Marquette and Northern Michigan University, this market has experienced surprising resilience and growth patterns that defy many rural Michigan trends.

With 287 total actively licensed agents serving the county, the market maintains a robust professional presence that reflects both local demand and the complexity of serving diverse property types ranging from lakefront estates on Lake Superior to historic mining town properties in Negaunee and Ishpeming. Remarkably, all 287 agents maintain email contact information, indicating a tech-forward approach uncommon in many rural markets.

Major Marquette County, Michigan Real Estate Markets

The city of Marquette dominates the county's real estate activity, driven by its role as the region's economic and educational hub. The university presence creates consistent rental demand and supports a surprising luxury market along the Lake Superior shoreline, where properties regularly command premium prices for their dramatic water views and recreational access. Marquette's downtown revitalization has sparked interest in historic commercial conversions and mixed-use developments.

Secondary markets in Ishpeming, Negaunee, and the numerous small townships offer more affordable options while maintaining access to outdoor recreation that increasingly attracts remote workers and retirees. The Gwinn area has seen unexpected growth as buyers seek larger parcels and rural settings, while communities like Harvey and Skandia benefit from their proximity to Marquette's amenities without the premium pricing.

Market Dynamics and Geographic Complexity

Marquette County's real estate market operates on distinct seasonal rhythms, with peak activity during summer months when the region's natural beauty is most accessible to out-of-state buyers. The market has shown remarkable adaptability, with agents increasingly specializing in serving buyers from downstate Michigan and neighboring states who discovered the area during the pandemic's remote work revolution.

Geographic complexity defines daily operations, as agents regularly serve territories spanning hundreds of square miles across diverse terrain. Properties range from urban condominiums near the university to remote wilderness retreats accessible only by seasonal roads. This diversity requires agents to maintain expertise across multiple property types and market segments, from first-time homebuyers to luxury vacation home purchasers.

Why Businesses Need Marquette County, Michigan Agent Contact Data

The complete email accessibility of all 287 licensed agents creates exceptional opportunities for service providers, lenders, and technology companies to reach this concentrated professional network efficiently. Given the market's seasonal intensity and geographic challenges, agents actively seek solutions for client communication, property marketing, and transaction management tools that can handle the unique demands of Upper Peninsula real estate.

The university presence and growing remote worker population drive consistent demand for renovation services, property management solutions, and specialized lending products. Companies offering these services can leverage direct agent contact to build relationships in a market where personal recommendations carry exceptional weight and where agents often serve as crucial connectors between service providers and property owners across vast rural territories.
