Hi! I am Kim Portner.  How can I help you?

There is no place like the Florida Keys.  A true turquoise water paradise with a casual island lifestyle... AND, if you are a US citizen, no need for a passport!  It is a privilege to spend time here.  I love it here and I am confident you will too once I have the chance to show you around.  I will help you navigate the Keys, answer your questions and help you find your dream property.  

If you are already here and are ready to upgrade or sell your property, I have the contacts, marketing strategies and expertise to sell your home timely and efficiently. 

Best Service, Best Results!

I love working as a Real Estate Professional.  It is a thrill to work helping clients, many of which become friends and neighbors, find a home and community that they love to spend time in.  I have the experience and local knowledge to help you make the best decisions when buying or selling in the Keys.  My training, commitment and diligence, ensure you have a professional at your side looking out for your best interest at all times.  

What makes the Florida Keys so special?

Gorgeous and converging bodies of water that are visible from just about everywhere.  World class fishing, kayaking, snorkeling, sandbar hopping, boating, the freshest seafood, wonderful local restaurants, beaches, state parks, endless breathtaking views, daily sunset celebrations.....I could go on but you get the idea.  This is a very special place.

Real Estate Market

Coldwell Banker Schmitt has been the number one Keys-wide real estate company for listings and sales since 2004.  We sell more properties than the next 4 companies combined. We have deep knowledge of our market trends, history and a proven marketing program that get the job done when selling and buying.  I would love the opportunity to meet with you and show you how I can assist you in meeting your goals.
