AI-selected highlights from the listing description below.

Discover the rare opportunity to create a legacy waterfront estate in the prestigious Harbor Section of Bay Isles, one of Longboat Key's most coveted boating communities. Tucked behind double gated, guard-secured entry, this exceptional 0.41-acre homesite boasts an impressive 135 feet of deep-water frontage, offering effortless access to Sarasota Bay and the Gulf of Mexico. Designed for those who embrace the waterfront lifestyle, the expansive canal frontage provides possibilities for multiple vessels and seamless days on the water. As a Bay Isles resident, you'll also enjoy deeded private access to the Bay Isles Beach Club, where miles of pristine Gulf beaches await. Perfectly positioned directly across from the world-renowned St. Regis Longboat Key Resort, this premier location places luxury amenities at your doorstep while maintaining the privacy and exclusivity of a gated waterfront enclave. Championship golf, marinas, waterfront dining, boutique shopping at St. Armands Circle, and the arts, culture, and fine dining of downtown Sarasota are all just minutes away. Whether you envision a contemporary coastal masterpiece or a timeless waterfront retreat, this remarkable homesite offers the ideal canvas to build the custom residence you've always imagined in one of Southwest Florida's most distinguished waterfront communities. Architectural plans are available upon request, with engineering complete. Capitalize on the extensive development work already completed, saving valuable time and expense while accelerating the path toward permitting and construction. An existing residence is situated on the property; however, the property is being marketed for its exceptional homesite and development potential.

Estimate the monthly payment

Estimate by Lasbury Tracy Realty — not a loan offer

Starting figures for 1600 HARBOR SOUND DR. Everything below is editable.

AssumptionNot a quoted rate. Ask a lender what you actually qualify for today.

From this listingThe seller's most recent annual tax bill as reported to the MLS. Your bill will differ — Florida reassesses on sale and homestead caps reset.

Editable estimateA placeholder, not a quote. On the Gulf Coast this is the line item most likely to be wrong: premiums swing on roof age, wind mitigation, elevation, and carrier appetite. Get a real quote before you rely on this number.

Starts at $0Deliberately zero until you enter a figure — we will not inflate a payment with a guess. Many homes here need it; ask us for the property's flood zone and the current policy's premium.

From this listingMonthly association fee as reported to the MLS. Confirm what it includes, and ask about special assessments.

AssumptionNot applied — your down payment is 20% or more.
