Why Ultra-Luxury Real Estate Now
Trophy assets have historically outperformed traditional investments during periods of economic uncertainty. Our proprietary intelligence platform tracks 47 micro-markets in real time, identifying value before it becomes apparent to the broader market.
- Off-market inventory at record levels
68% of our current listings never appear on public platforms, available exclusively to Onyx clients.
- Prime international markets stabilising
Monaco, Gstaad, and Palm Jumeirah have all shown 8–14% year-on-year appreciation since 2022.
- Currency diversification through property
Our multi-currency portfolio strategies protect UHNW clients against single-market exposure.
