Even those who can invest face challenges: properties can’t be easily sold on short notice, and managing tenants and maintenance is labor-intensive. Moreover, small investors often lack diversification since it’s hard to split one property into fractional ownership. **Subunit** is a real estate tokenization protocol reimagining how people access and manage property ownership in a crypto-native way 🔗 Our vision reflects a new approach: instead of large capital outlays and illiquid holdings, Subunit enables **fractional ownership** of real estate through blockchain tokens, providing **24/7 liquidity** and **global access**. The platform operates under an **investment club model**, meaning that each participant is not a passive investor but an active member of a club that co-owns and governs properties.
