BULL CASE

If Castle Cove maintains 3%+ annual growth and vacancy stays below 1.1%, median prices could reach $4,684,731 within 3 years with yields compressing slightly as capital values rise.

BEAR CASE

A market correction or interest rate shock could see prices in Castle Cove pull back 10-15% from $4,073,679, with vacancy rising to 2.9% and rental yields softening as tenants gain leverage.

KEY RISKS
