About this home
Experience the pinnacle of island living, a stunning coastal retreat nestled in the heart of Key Biscayne. This bright and airy residence offers an open-concept layout that seamlessly blends modern elegance with the relaxed charm of the Florida lifestyle. Just steps away from the pristine sands of the Atlantic, the property provides exclusive access to private beach paths, lush tropical landscaping, and a serene atmosphere that feels miles away from the city—yet is only minutes from downtown Miami. Whether you’re enjoying the ocean breeze from your private balcony or taking advantage of the boutique building's premium amenities, this is a rare opportunity to own a piece of paradise in one of South Florida’s most prestigious zip codes. Some images in this listing have been virtually staged to better illustrate the potential layout and spatial possibilities of the home for conceptual purposes only.

Location
Approximate — shows the building, not the unit.
Run the numbers
We fill in the price and the building's HOA dues. That leaves tax, insurance and maintenance — they depend on your exemptions, your insurer and the unit, so we don't guess them. Rent starts from what comparable units are asking nearby. Vacancy and the loan terms below start at common defaults; change them.

Cap rate
Cash-on-cash
Monthly cash flow
Net operating income
Enter property tax, insurance, maintenance to see the returns. A cap rate calculated without every cost overstates the deal — often by half — so we don't show a partial one.
Illustration only — not a loan offer, quote, or investment advice. We are not a lender and neither offer nor arrange financing. The loan fields start at 20% down over 30 years at 6.5% (rates as of July 2026); that is a nominal rate for illustration, not an APR, and your actual terms will differ. Cap rate is unlevered; cash-on-cash counts the down payment as invested capital and excludes closing costs.
