This week's standout ultra-luxury estates — October 2 to October 8, 2026

Why this tier, why now
At $75M and up, you're buying position — water, skyline, and the few addresses that never add inventory. Three waterfront mansions from Biscayne Bay to Sunset Islands, two Miami Beach trophy condos, and a 19,868-square-foot triplex penthouse in a 2024 branded tower. The list runs from $75M to $110M with no filler.
If one of these six fits your plan — primary residence, legacy asset, or a long-hold play — tour it this week. Estates at this level don't wait.
