About this home
Casa Mar combines the privacy and outdoor living of a beachfront home with the services and security of a luxury boutique oceanfront building. The combined southeast-corner penthouse offers four bedrooms, four and a half bathrooms and 3,357 square feet of interiors, plus a rare 3,500-square-foot private rooftop with a kitchen, stone bar, pergola, entertaining areas and panoramic ocean views. Curated by cultural placemaker Ximena Caminos, with architectural consulting by Galia Solomonoff, the residence features soaring ceilings, multiple oceanfront balconies and white marble floors. Details include hand-painted murals by Argentine artist Augusto Falopapas, a champagne-mirrored ceiling and a pink-onyx kitchen with white-oak cabinetry and rose-gold hardware. The primary suite includes a spa-like bath and custom dressing room. Originally designed in 1941 by noted Art Deco architect L. Murray Dixon, The Caribbean offers direct beach access, beach and pool service, an infinity pool, spa, and cabanas. Located on Miami Beach’s iconic Millionaire’s Row near the Faena District, The Miami Beach EDITION and Soho Beach House, with Casa Cipriani Miami Beach and Aman Miami Beach joining the neighborhood, Casa Mar is a singular opportunity to own a private retreat in one of Collins Avenue’s most architecturally significant boutique oceanfront buildings.

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.
