FAQ
When buying on Marco Island, I always advise clients to look beyond the listing price and consider the full picture, including flood zones, insurance costs, seawall and dock condition, HOA rules, and even bridge clearance if boating is part of their lifestyle. Each neighborhood has its own character, from the luxury high-rises at Cape Marco to the golf and beach community at Hideaway Beach, so it is important to match the property to how you want to live here. Having guided clients through these nuances for over 15 years, I help ensure they make confident, well-informed decisions on Marco Island’s unique market.
When I advise sellers on Marco Island, I always emphasize that presentation and positioning are everything. In today’s market, buyers of luxury homes, waterfront properties, and beachfront condos are very selective, and even small details can make the difference. Making sure your property shows at its absolute best, from curb appeal to interior updates and staging, goes hand in hand with pricing it strategically. I pair that preparation with a proven marketing strategy that includes professional photography, targeted digital campaigns, and global exposure through the Sotheby’s International Realty network. With over 15 years of experience as a full-time Marco Island Realtor, I help sellers navigate every detail so their home stands out and sells with confidence.
I have had the privilege of working with a wide range of clients on Marco Island, from local families and retirees to buyers relocating from across the country and abroad. Many of my clients are drawn to Marco Island for its luxury waterfront homes, beachfront condos, and second-home opportunities, while others are selling properties they have owned for years as they move into a new stage of life. I also work closely with investors who see the long-term value in Marco Island real estate. Through my Sotheby’s International Realty network, I frequently collaborate with referral clients from other markets, ensuring a seamless experience whether they are buying or selling. No matter the situation, I am committed to providing expert market knowledge, clear guidance, and trusted results tailored to each client’s goals.
$11,000,000 Record Setting Marco Island Off-Market Waterfront Home Sale
I represented the sellers of this luxury Marco Island property in an $11 million off-market transaction. The owners were out of town, so I managed every detail on their behalf. From preparing the home for private showings to attending inspections and working with my trusted network of tradesmen and service companies to address inspection items, I ensured a seamless process. By collaborating closely with the buyer’s agent, we were able to close ahead of schedule and deliver outstanding results for my clients. As part of Premier Sotheby’s International Realty, I combine hands-on, detail-oriented service with the global exposure and resources of the Sotheby’s brand to achieve exceptional results on Marco Island.
I began my real estate career after relocating to Marco Island in 2009. Before that, I worked in medical sales with GE Healthcare, where I developed strong skills in client service, negotiation, and relationship building. Having visited family here for many years, I was already passionate about Marco Island real estate and often enjoyed visiting open houses at beachfront condos and waterfront homes. When I made the move full time, becoming a Marco Island Realtor felt like a natural step, allowing me to combine my professional background with my love for this community.
