High-Demand Rental Model - ADU/J-ADU Inclusion: Projects premium rents using tri-county (Orange/San Diego/Riverside) comps   - Proven Precedent: Maintenance/design benchmarks from award-winning Santa Luz/Cielo communities    6. Risk-Mitigated Execution - Geotech Complete: Keller ground-improvement plan locked   - Top-Tier Team: Design/engineering leads with regional success track records    ---    Why Invest Now?
