Meet Debbie Koster

Originally from Long Island, NY, I have been a resident of the Treasure Coast for 40 years. I have been a full time Real Estate Professional since 1998 specializing in residential sales and marketing, distressed properties, short sales, relocations, land sales and investment opportunities. I work diligently to help my clients make the best buying and selling decisions by staying abreast of changes in our market, the real estate industry and the latest technology. Continuing education is also very important to me to help better serve my clients.

I am a member of the Realtors Association of St. Lucie, the Florida Association of Realtors, and the National Association of Realtors. I am a sponsor of the Children's Miracle Network, the Koman Breast Cancer Foundation and the American Little League.

I look forward to hearing from you and helping you with all of your Real Estate needs.

Meet Milton W. Koster

I am originally from The Pocono Mountains of Pennsylvania, East Stroudsburg to be exact. In 1977, with the advise of my parents, I started investing in Port St. Lucie, FL property. They would say “Invest in land, they're not making any more of it”. So I did!

In 1985, I moved from PA to the Treasure Coast of Florida and started my own business Milton W. Koster Real Estate Investments, also now known as This business would specialize in offering undeveloped Port St. Lucie lots to ANYONE who was interested in owning a piece of the "American Dream" regardless of credit history by offering Easy Owner Financing with No Credit Checks and No Qualifying.

And now, after over 30 years of being in the Real Estate industry, I have joined the Re/Max Masterpiece Realty team were I will be able to give a full service opportunity to my clients of old and new. I specialize in Vacant Land, Residential Homes and Waterfront Living, representing both Buyers and Sellers.

Thank you for the opportunity in allowing me to help YOU with Buying, Selling or working with you to accomplish your Real Estate Investments
