Overview

Outstanding Waterfront Redevelopment or Restoration Opportunity! Rare point lot in Causeway Isles with 148 feet of direct water frontage and wide-open Boca Ciega Bay views. Enjoy a southern rear exposure offering both sunrise and sunset vistas. Located at the end of a quiet cul-de-sac, this property features deep water with no fixed bridges and quick access to the Gulf of America. The existing 4-bed, 4-bath, 2,522-sq-ft home was flooded and remediated after Hurricane Helene and qualifies for restoration under FEMA’s 50% rule with an updated appraisal. Ideal for a builder, developer, or buyer ready to renovate or rebuild a custom waterfront residence. Minutes to Treasure Island beaches and vibrant downtown St. Petersburg. A premier location and rare opportunity—don’t miss it!
