Agent Description

Embrace the RARE opportunity to own 1.75 acres of open water paradise in the prestigious, gated community of Stirrup Key.

Five protected basin docks provide sheltered boating access in the marina, while terraced tropical gardens cascade toward the water, lined with mature palms and lush landscaping for a serene coastal ambiance.
