About this home

BRAND NEW SE CORNER PENTHOUSE at UNA Residences with absolutely breathtaking, unobstructed views of Biscayne Bay, the Atlantic Ocean, Key Biscayne, and the Miami skyline. This exceptional 5BD/6.5BA residence features soaring, unique 13-FOOT CEILINGS, floor-to-ceiling lift-and-glide glass doors, and an expansive wraparound terrace. The thoughtfully designed layout includes a separate staff quarter, a private elevator entry, and marble floors already installed throughout. The chef’s kitchen is equipped with top-of-the-line Gaggenau appliances and an inviting breakfast nook. The expansive primary suite is filled with natural light from its floor-to-ceiling windows and offers dual bathrooms and oversized walk-in closets. Designed by Adrian Smith + Gordon Gill Architecture, with landscape design by Enzo Enea, UNA is a boutique and private building inspired by classic yacht design and world-class amenities, including three pools, a gym, and a spa envisioned by the chairman of AMAN. Positioned in one of Brickell’s most coveted waterfront enclaves, at the gateway to Key Biscayne, UNA offers both tranquility and convenience, with immediate access to Brickell, Coconut Grove, Downtown, and the beaches of Key Biscayne.

Run the numbers

We fill in the price and the building's HOA dues. That leaves rent, tax, insurance and maintenance — they depend on your exemptions, your insurer and the unit, so we don't guess them. Vacancy and the loan terms below start at common defaults; change them.

Cap rate
Cash-on-cash
Monthly cash flow
Net operating income

Enter rent, 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. 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.
