From the listing
Offered for the first time in 40 years, this gated waterfront point-lot estate occupies the coveted west tip of Sunset Island III, with unobstructed Downtown Miami skyline views and spectacular sunsets. Designed in 1937 by renowned architect T. Hunter Henderson, the 5-bedroom, 5.5-bath Art Deco residence preserves beautifully restored original details, including arched windows, decorative ironwork, hand-painted Cuban tile floors and staircase. Thoughtful updates include impact windows and doors, Control 4 smart home technology, 3-zone A/C, and dual walk-in closets in the primary suite. A spacious private terrace overlooks Biscayne Bay, while a concrete dock with a 17,000-lb boat lift enhances the waterfront lifestyle. Set on an exceptional 13,771-SF pie-shaped lot, this rare offering presents the opportunity to preserve a piece of Miami Beach history or build your dream waterfront residence in one of the area's most prestigious guard-gated island communities.
Monthly payment calculator
Rate: 7.24% 30-year fixed average (Freddie Mac, week of October 29, 2026). Your own rate may differ; you can change it here.
Estimate, not a loan offer. Tax default: the higher of the seller's bill and about 1.9% of price (Florida resets a new owner's assessment). Insurance default: Florida OIR county average with wind, data as of Mar 31 2026. Rate is an assumption; your lender sets the real one. Zach doesn't take lender or title referral fees.
Florida risk facts
- Flood zone
- Zone AE: high-risk flood area. A FEMA Special Flood Hazard Area (about a 1% chance of flooding each year). Lenders require flood insurance for federally backed mortgages here. Source: FEMA National Flood Hazard Layer, checked Nov 1, 2026. This is a map lookup, not an official flood zone determination.
- Wind and building code
- Built in 1937, before the statewide Florida Building Code took effect in 2002. Ask for the wind mitigation report; it can lower insurance. My Safe Florida Home offers free inspections and grants when funded.
- Disclosure
- Florida sellers must give you a flood disclosure about known flood damage, insurance claims and federal assistance (§689.302).
We don't show crime scores or rate neighborhoods. Every listing is open to everyone.
Start an offer
- Pre-approval letter or proof of funds (cash)
- The price you'd offer and your deposit
- Financing type and closing date
- Inspection period you want (often 10-15 days)
- A signed buyer agreement with Zach (Florida practice before touring or offering)
Nothing here is a binding offer. Zach calls you, checks the comps and writes the contract with you.
