A Closer Look
Set above the shores of Crescent Lake, this historic residence, originally known as The Williams Home and later as the Mary-Edward Inn, offers a rare blend of legacy and livability. Built in the 1800s and once operated as a bed-and-breakfast, the property carries a presence shaped by generations drawn to the lake's quiet rhythm. Now configured with five bedrooms plus a dedicated office, the home has been thoughtfully updated with a renovated kitchen and modernized baths, balancing everyday comfort with the preservation of architectural character. Positioned high on a bluff overlooking a lake connected to the St. Johns River, the setting offers expansive sunrise vistas, freshwater views, private water access, and a distinctly unhurried Florida lifestyle. A property defined not just by its history, but by the experience it continues to offer.

Mark Bouchard
"The most important question in real estate isn't what a property is worth. It's what you're trying to accomplish."
That distinction has shaped Mark Bouchard's approach to the business. A property may be the asset being bought or sold, but the real work is understanding the decision behind it. Where is the client trying to go? What matters in getting there? And what strategy gives them the best chance of achieving it?
A native Floridian, Mark grew up around real estate and construction and has spent more than 25 years in Atlantic Beach. His professional career has been built around sales, business, and entrepreneurship. For nearly two decades, he competed at a high level in the medical device industry, then built businesses in marketing and technology. That experience developed a perspective grounded in strategy, negotiation, marketing, and understanding what drives people to make decisions. Real estate brings those experiences together.
Today, Mark is a real estate advisor with Douglas Elliman, working across Florida with particular depth in Northeast Florida and the Space Coast. His business includes luxury residential and waterfront properties, commercial real estate and investment opportunities. He works with business owners, executives, investors, families, and individuals, making decisions that often involve far more than simply choosing a property.
Mark brings the same approach to every assignment. Understand the objective first, then determine the strategy. For a seller, that may mean identifying the right audience, positioning the property differently and creating a marketing strategy around what actually makes it valuable. For a buyer or investor, it may mean questioning value, challenging assumptions, negotiating harder, or recognizing when the right decision is to walk away. The circumstances change, but the responsibility doesn't.
Mark believes good representation isn't measured by whether a transaction gets done. It's measured by whether the outcome serves the client. Sometimes the best advice moves a deal forward. Sometimes it changes the strategy. And sometimes it's simply, "I don't think you should do this." That's not getting in the way of a transaction. That's doing the job.
