INFRASTRUCTURE & CATALYSTS

BULL CASE

If Marmion maintains 3%+ annual growth and vacancy stays below 0.8%, median prices could reach $2,514,520 within 3 years with yields compressing slightly as capital values rise.

BEAR CASE

A market correction or interest rate shock could see prices in Marmion pull back 10-15% from $2,186,539, with vacancy rising to 1.6% and rental yields softening as tenants gain leverage.

KEY RISKS

  • Premium price point limits buyer pool and increases interest rate sensitivity
