Marathon & Key Colony Beach Homes for Sale | Florida Keys Real Estate Expert

Welcome! I’m Amy Puto, and I’ve been helping families find their perfect island home since 2001. While my website provides a direct MLS feed for all Florida Keys real estate—including Key Largo, Islamorada, the Lower Keys and Key West—my local expertise is rooted right here in Marathon and Key Colony Beach.  If you are looking to buy a home in our community, you’ve come to the right place for honest, local and experienced guidance, as well as the most informative site in the Keys for buyers and sellers.

Expert Guidance for Home Buyers & Sellers

Selling real estate in the Keys requires more than just an MLS login. It requires an understanding of canal depths, flood zones, insurance, and the unique nuances of island living. With over 20 years of experience as a Top Producing Agent with Coldwell Banker Schmitt, I specialize in:

  • Waterfront Single-Family Homes: Helping you find the perfect dockage and sunset views.
  • Luxury Estates:  Expertly showing and marketing high-end homes to serious buyers.
  • Investment & Resort Properties: Specializing in the purchase of homes with 7-day rental rights. (Note: I focus exclusively on real estate sales and do not handle rental bookings).

Stay Informed with my Weekly Market Report

Since 2008, I have personally curated a Florida Keys Weekly Market Report to keep my clients ahead of the curve. This report tracks every new residential listing, price change, and home sale in the Marathon area, as well as the Upper Keys, Lower Keys, and Key West.

My clients find this data-driven update invaluable for monitoring market trends and finding the best deals before they disappear. There is no obligation, and you can unsubscribe at any time.
