BUY2.8% gross yield on a $1,290,000 median.

THE MARKET

Blackwood has compounded at 4.4%/yr over 5 years — a house that cost $1,040,129 in 2021 is worth $1,290,000 today. Properties are sitting on market for 20 days (sellers have the leverage). At the same growth rate, today's median reaches $1,599,898 by 2031.

  • Landlord market — rents likely to keep rising.

BULL CASE

If Blackwood maintains 3%+ annual growth and vacancy stays below 0.8%, median prices could reach $1,483,500 within 3 years with yields compressing slightly as capital values rise.

BEAR CASE

A market correction or interest rate shock could see prices in Blackwood pull back 10-15% from $1,290,000, with vacancy rising to 1.4% and rental yields softening as tenants gain leverage.

KEY RISKS

  • Bushfire risk: HIGH (planning_overlay) — confirm BAL rating and any bushfire overlay obligations for the property
