It’s rare to find someone in real estate as tireless, selfless, and genuine as Margie. She doesn’t approach her work with the goal of making a sale—she approaches it with the goal of helping people. Every conversation, every showing, and every bit of advice she gave was focused on what was truly best for me, whether that meant buying a home or simply learning more about the process. Margie spent an incredible amount of time and effort guiding me, not because she wanted to close a deal, but because she genuinely cared. Her patience, honesty, and dedication are unmatched. If you’re looking for someone who will always put your interests first, educate you, and truly go above and beyond, Margie is that person. She’s not just a phenomenal agent—she’s a wonderful human being.
Margie Casey is the epitome of an all-star realtor! She is personable, detailed, highly knowledgable of the Florida Keys real estate market and local vendors...most importantly, Margie is such a kind-hearted and thoughtful professional. We are grateful she went the extra mile to ensure a smooth experience for both sides of this transaction. It was a pleasure working with her and we are excited to continue our relationship with the Brenner/Casey team on this next adventure. Look no further-- they are a package deal in Duck Key, Marathon: sales, property management, investments, seasonal rentals and wonderful Five Star service!
Margie is a local expert. I was very impressed on both her knowledge and speed to assist me in finding a short term rental in Marathon. Outstanding team and would work with them again in future.

Kasey Platt was amazing when we purchased our home in Key Colony Beach, Florida! Words can’t fully grasp the ease and comfort of buying a house with Kasey as your agent! Our entire process was just over 30 days and we did everything FROM NEW JERSEY! Easiest real estate transaction EVER! Kasey took care of literally everything…and anticipated things before they even happened, and had them handled too! I would recommend Kasey to anyone looking to buy or sell in Florida! That’s how wonderful she is! As an added bonus …she is handling the rental of our home too! She does it all! Thank you, Kasey!
My husband and I worked with Kasey while buying a Condo in Marathon. Kasey was both professional and a pleasure to work with. She went above and beyond to help us every step of the way. She accommodated us greatly since we were out of state buyers. The process went smoothly with her help. We bought our condo /vacation dream home and couldn’t have done it without her guidance. We highly recommend her !! Thank you Kasey .
Kasey is absolutely fantastic! I knew right away I wanted to work w/ her after our first conversation (an hour long on a Friday after 5:00!). She has a tremendous wealth of knowledge, is from the area and knows a ton of locals in every kind of business imaginable. We found our dream house very quickly and Kasey helped us with the buying process every little step of the way. She is extremely determined and has an unbelievable work ethic. During the pending period all the way until the day of closing Kasey was checking on the status of things daily and keeping us posted way more than any other realtor we have had previously. We trust Kasey w/ our new home and are very excited to continue our relationship w/her as our rental manager.
Kasey was amazing! Searching and buying a house was always stressful for me. But She helped us a lot during the entire processed from searching until we found the right one for us to buy🥰. Shes Very easy to communicate with and very responsive when you have any concerns or questions. We will definitely recommend here. Thank you Kasey for everything! We love our home.
Buying a home felt like the biggest adventure for our family—and we’re so glad Kasey was the one leading the way! 💕 From the very first moment, it didn’t feel like working with an agent—it felt like having a trusted friend by our side. Kasey was our dedicated buyer’s agent, and she went above and beyond in every way. She truly listened to what we wanted and needed, and she never rushed us. Instead, she guided us with patience, insight, and expertise—helping us understand the market, comparing properties, and making sure we felt confident every step of the way. Being a true Marathon local, she knows every corner of the Keys. 🌴✨ She didn’t just show us houses—she helped us imagine our family’s future here, pointing out neighborhoods, hidden gems, and little details only someone deeply rooted in the community would know. What we appreciated most was her heart. She wasn’t just focused on finding a house—she was committed to finding us the right home. She was tireless in her search, quick to answer questions, and always advocating for us throughout the entire process. We couldn’t recommend Kasey more—she made the home-buying process not only smooth and stress-free, but also exciting and joyful. 🏡💗 Sent from Front

We recently purchased a home with “The Brenner Scheel and Casey Team”. They helped us navigate through the process and helped us gain a better understanding of the areas we were looking at. They showed us many properties and answered our many questions. They also connected us with other professionals we needed in the area. Very professional team and I would highly recommend them.
There are not enough good words to describe Kristen Brenner and Duck Key Real Estate. Kristen is the Epitome of what a Real Estate Agent and human being should be. She made the purchase of our house a breeze. With her years of experience in both the Real Estate business and living in the keys she was able to connect us with lenders, insurance agents and contractors. I would hands down recommend Kristen and her team to anyone looking to purchase a house in the Keys.

This team truly functioned like a real team and got my Key West house sold. Even brought a cash buyer! Highly recommend!
Very knowledgeable and service oriented staff. Always available when needed. They handled our sale and purchase on Duck Key with speed and professionalism. Highly recommend.
We can’t speak highly enough of Margie Casey and her entire team at Florida Keys Real Estate Group. Her professionalism, knowledge, honesty, and integrity were very much appreciated when we purchased our home in Duck Key. She made the process very gratifying and was always available for any questions or concerns we had along the way. We liked her so much that we are working with her a second time on selling our property in Marathon. Thanks again Margie and Kristin!!!
Margie Casey was very helpful with the closing of a house we purchased. She kept us informed on the status as it was an unusual sale. Thank you for responding to all my questions and being patient with us.
The level of professionalism and knowledge of home buying in Marathon is absolutely Margie Casey! Margie showed us EVERYTHING available on the market and explained everything we needed to know before purchasing. Our trust was with Margie once we left the keys and still looking. She found us a home and we signed a PA from pictures and from Margies word that we would love it. January we came down to see our new home and loved it! She knew exactly what we wanted and where our numbers had to be. We are so happy with our new home and thank Margie a ton for all she did for us! 10 Stars for Margie and her team!! Thank You!
Kristen and Margie are the best seller's agent in Marathon. They went the extra mile to get the best deal for our house on Duck Key. Kristen and Margie have a depth of experience and superior knowledge of the Marathon market that is second to none.
Great experience with Kristen and Margie. They are without a doubt two of the best realtors in Marathon and Duck Key. Very accommodating to our schedule and knowledgeable. They found us exactly what we wanted and were there for every step of the way. Highly recommend!
Kristen and Margie are an absolute wealth of knowledge when it comes Real Estate! Not only did we have a pleasurable buying experience when we first purchased our keys home in 2018 but they’ve assisted us in navigate through the ownership process as well. These two make an awesome team, they are the realtors that became our lifetime friends❤️
Kristen and Margie are an outstanding team to work with. They are very knowledgeable, professional, and their responsiveness was incredible. They took the time to listen to our desires and needs for our future home and they delivered. Kristen and Margie truly care about their clients which is emulated throughout the entire process.
Bought a property and lived 1000 miles away. Looking at homes would be quite challenging. Margie Casey had everything lined up and only required one trip. Within a half day she had found the perfect one for us. Navigating the Real Estate market in the Keys is dramatically different than my home state. She walked us through every step. Set us up with lenders, inspectors, insurance, even a new social place (Marathon Yacht Club). She was our onsite person through the whole step. Knowledgeable and our advocate in every sense of the word. I cannot recommend more highly.
Thank you so much Kristen and Casey. We are so happy to have had you both as our realtors. You answered all our questions and got our beautiful home on Duck Key sold. I’m sooo grateful and Blessed to have you as friends. God Bless you both in all your hard work getting our home sold. May God continue to bless you.
Top notch service with Margie Casey! A real pleasure to work with. Helped us every step of the way in finding and negotiating our vacation home property in the lower keys. We can’t thank her enough! If you’re looking for someone who is highly knowledgeable and knows the market in this area, Margie is a must go to!
Margie and Kristen are awesome! From home search to close they take care of everything. Highly recommend using them for your next home purchase.

Kristen is the one you want on your side! She’s so knowledgeable about the market and is a true native which makes her super connected to the community. She will always be our first call.
We had an outstanding experience working with Luis Parrado and Tierce Scheel during the purchase of our property in the Florida Keys. From contract through closing, Luis was our main contact and he was knowledgeable, professional, and incredibly responsive. He guided us through every step of the process, answered our many questions promptly, and helped us navigate several unexpected issues with confidence and expertise. We would definitely use them again and highly recommend working with them.
I recently had the pleasure of working with the Brenner, Scheel and Casey real estate team while searching for my forever home on the stunning island of Duck Key, Florida. From the very beginning, Margie was an absolute standout. Her dedication and attention to detail made the entire process not only smooth but also enjoyable. Margie’s thoroughness in understanding my needs and preferences was remarkable. She took the time to listen, ensuring that every aspect of my dream home was considered. Her knowledge of the local market and the unique features of Duck Key was invaluable, guiding me to homes that truly aligned with my vision. What truly set Margie apart was her genuine friendship throughout the journey. She was always there to provide support, answer questions, and address any concerns, making me feel like I had a trusted partner by my side. It was clear that she had my best interests at heart, which made the experience all the more reassuring. I am incredibly grateful for Margie’s assistance and the Brenner Casey team’s professionalism.
