Mariner Cay is a small waterfront community in Palm City, Martin County, built around access to the water rather than sprawl. Most homes here come with a pool, and boaters find the location close to the St. Lucie River appealing — three of the four current listings sit on the water. It's the kind of place where the pace stays quiet and the neighbors know the tide charts. If you're weighing options, it's worth comparing against nearby Palm City homes for sale and communities like Pine Ridge At Martin Downs.
The market here is thin and wide-ranging: just four active listings with a median list price of $406,500, but a spread that runs from $322,000 up to nearly $2.6 million. Homes average $371 per square foot on a median size around 1,524 square feet, and they tend to sit — median days on market is about 112.
