Bill Underdown has become one of the most trusted real estate agents in Michigan, building his reputation through years of consistent work and genuine relationships with clients. Based in the Saugatuck area, he specializes in lakeshore communities in Southwest Michigan, helping buyers and sellers navigate a market that draws people looking for second homes, retirement properties, and investment opportunities.

Since joining Century 21 Affiliated in 2016, Bill has ranked as a Top Producer and earned a place in the Centurion Award’s Honor Society. In 2025, he celebrated five consecutive years of top sales performance, a milestone that reflects the steady trust his clients place in him. He has also received multiple Quality Service Awards and holds certification as a Luxury Home Agent through the Century 21 Fine Homes and Estates platform. These achievements did not come overnight. They are the result of showing up for clients year after year and delivering dedicated service each time.

Understanding the Lakeshore Lifestyle

What sets Bill apart is his understanding that real estate on the lakeshore is about more than transactions. The buyers he works with are not just purchasing property. They are choosing a way of life. “The Lakeshore community is made up of people who chose to live here,” he explained. This insight shapes his entire approach. His goal is to match buyers with properties that fit the lifestyle they are seeking, not just the specs on paper. He takes time to understand what each client is looking for and works to find homes that will serve them well for years to come.

Every buyer Bill works with receives a membership to the Saugatuck Center for the Arts. It is a small gesture, but one that speaks to his commitment to connecting people with the community itself. For Bill, the relationship does not end at closing. He wants his clients to feel at home in the fullest sense of the word.

A Hands-On Approach to Marketing

Bill and his team create custom marketing materials across social media, print ads, and custom websites for their properties. Utilizing high quality photography, videography, and drone footage, their goal is to create a unique feature for each property to tell their story. Because all materials are created in-house, the team can produce captivating in-the-moment content to post for upcoming open houses or other activities on their properties. Clients receive weekly updates so they know exactly how many views their property listing is getting and also where viewers are seeing it across various websites. This level of transparency keeps sellers informed and reassured throughout the process.

Deep Roots in the Community

Bill’s network runs deep in the area he serves. He is actively involved with organizations like the Saugatuck Douglas Convention and Visitors Bureau, the Saugatuck Douglas Historical Society, Ox Bow School of Art and Artists’ Residency, and the Saugatuck Center for the Arts. These connections allow him to offer resources that extend well beyond the closing table, helping newcomers settle into a place that means something to the people who live there.

He has also expanded his reach into key feeder markets, including Palm Springs, Chicago, Detroit, Indianapolis, and St. Louis. Bill has sponsored events like the Red Dress/Dress Red Fundraiser in Palm Springs and participated in the Chicago Pride Float, strengthening ties with potential buyers who may be looking toward Michigan’s lakeshore for their next chapter. This broader presence helps him connect sellers with qualified buyers from outside the immediate region.

Trust as the Foundation

At the core of Bill’s work is a simple belief in building trust. “The key is building relationships,” he said. His clients appreciate his energy and dedication, and that appreciation shows in the referrals and repeat business that sustain his career. He does not chase new leads at the expense of existing relationships. Instead, he focuses on doing right by the people who have already placed their confidence in him.

Bill also enjoys mentoring and partnering with other realtors, passing along what he has learned over the years. He sees value in lifting others rather than treating the industry as a competition.

For anyone looking to buy or sell along Michigan’s lakeshore, Bill Underdown offers something reliable: honest work, local expertise, and a genuine care for the community he calls home.
