Description

Views, Views, Views! An unparalleled expression of coastal grandeur, this extraordinary waterfront estate showcases luxury living in the heart of Aqualane Shores, one of Old Naples prestigious neighborhoods, just minutes to the Gulf of Mexico, a short distance to the beach and downtown’s historic Third Avenue South. Positioned along one of the community’s widest canals, this architectural masterpiece captures the essence of Old Naples elite lifestyle, where timeless design, masterful craftsmanship and effortless elegance converge. A boater’s and car collector’s dream, the 6, 130-square-foot residence seamlessly blends old Florida charm with refined sophistication, highlighted by exquisite millwork, rich hardwood flooring, shiplap accents and tranquil water views throughout the home. Designed for grand entertaining and intimate gatherings, the open-concept layout features a dramatic two-story great room, a gourmet kitchen with dual islands, and a spacious family room flowing naturally to a covered lanai with outdoor kitchen, pizza oven and fireplace. The primary suite, on the main level, affords the utmost privacy and elegance, featuring dual dressing areas and an adjoining study that easily transitions into an additional guest suite when desired. A separate guest residence, reached by private elevator, offers a full kitchen and living area, ideal for extended stays or hosting with complete independence. Among the home’s many refined appointments are a temperature-controlled 500-plus bottle wine room, a stylish wet bar, a secure safe room and an impressive 12-car garage designed for the connoisseur of fine automobiles. Outside, the resort-inspired grounds unfold with a waterfront vanishing-edge pool, spa, putting green and a private boat slip with a 34, 000-pound lift offering seamless, bridge-free navigation from your backyard to the open Gulf of Mexico, where turquoise waters and endless horizons await, completing this extraordinary tropical retreat.

Active Carriers in This Market

Citizens Property Insurance

Florida's insurer of last resort. Available if private market declines. Strict eligibility rules post-2023 reforms.

Universal Property & Casualty

One of the largest private carriers still writing in SWFL. Rates have increased significantly since Ian.

Florida Peninsula Insurance

Active in Collier and Lee County. Competitive for newer construction homes.

Security First Financial

Writing policies in SWFL. Strong for homes with impact windows and newer roofs.

Chubb / AIG (Luxury tier)

For homes above $1M. Offers agreed-value policies and broader coverage. Rates are higher but coverage is more comprehensive.

🏠

Impact Windows = Lower PremiumVerified impact-rated windows and doors can reduce wind premium by 15–30%. Always request the wind mitigation credit report from seller.

📋

Roof Age is CriticalMost SWFL carriers will not write policies on roofs over 15 years old. A roof over 10 years old triggers higher premiums. Request permit history before making an offer.

📐

Elevation Certificate Saves MoneyFor flood insurance, an elevation certificate showing the home is above Base Flood Elevation can cut NFIP premiums by 50% or more.

⚡

Get Quotes Before ClosingIn SWFL's current market, insurance quotes must be in hand before removing financing contingencies. Some homes in high-risk zones cannot be insured at any reasonable price.

Compare Insurance Rates → Insurance Guide

Insurance estimates are ranges based on current SWFL market conditions, ZIP code risk profiles, property type, and price tier. Actual premiums depend on specific carrier, coverage selections, roof age, construction type, wind mitigation credits, elevation certificate, and claims history. These are estimates only — not quotes. Always obtain binding quotes from licensed Florida insurance agents before closing. The SWFL insurance market has been volatile since Hurricane Ian (2022) and rates continue to change. Estimates reflect approximate 2024-2025 market conditions.

Equity Growth vs Total Cost Paid — Naples Historical Avg (~5%/yr)

True cost of ownership calculations are estimates based on inputs provided and SWFL market averages. Mortgage P&I uses standard amortization. Property tax uses the effective rate at purchase price. Insurance uses ZIP-based estimates. Maintenance reserve is set at 1% of purchase price annually — a conservative industry standard. HOA fees are pre-filled from MLS data where available. Appreciation scenarios are illustrative — Naples has averaged approximately 5% annual appreciation over the past 10 years but past performance does not guarantee future results.

What to Ask Before You Buy

✅

Impact Windows & Doors

Verify all openings are impact-rated. Retrofitting after purchase costs $30,000–$80,000+ on a large home. Ask seller for permits.

📋

Roof Age & Material

Insurance carriers in SWFL require roofs under 15 years old. Metal or concrete tile preferred. Request roof permit and last inspection report.

🔌

Generator & Transfer Switch

Whole-home generator is standard at the luxury tier. Verify fuel type (natural gas preferred), capacity, and last service date.

🏘

Evacuation Zone

Collier County uses zones A–E. Zone A is highest risk and evacuates first. Check Collier County EM for this address.

Check Evacuation Zone → Hurricane Guide

Risk scoring is based on NOAA HURDAT2 historical storm track data (1851–2024) and Collier/Lee County proximity analysis. This is a historical risk assessment, not a forecast. All construction in Florida must meet the Florida Building Code hurricane standards enacted after 2002. Verify current insurance availability and windstorm coverage requirements with a licensed Florida insurance agent before purchase.
