BULL CASE

If Seaforth maintains 3%+ annual growth and vacancy stays below 1.1%, median prices could reach $4,419,297 within 3 years with yields compressing slightly as capital values rise.

BEAR CASE

A market correction or interest rate shock could see prices in Seaforth pull back 10-15% from $3,842,867, with vacancy rising to 2.9% and rental yields softening as tenants gain leverage.

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