IRSAD vs Property Growth — Whitepaper & No-Go Zones Register

Description

What’s Included

This product contains two comprehensive PDF documents:

1. IRSAD vs Property Growth — Whitepaper A full statistical analysis examining the relationship between IRSAD socio-economic scores and 5-year property growth across 4,440 Australian suburbs. Reveals the Crossover Effect — the critical IRSAD threshold where high socio-economic standing begins to suppress capital growth — and identifies the investment sweet spot where growth potential is maximised.

2. No-Go Zones Register — IRSAD A severity-rated register of 426 Australian suburbs where long-term property investment carries elevated risk based on IRSAD Crossover Effect, Friction Ceiling, and Socio-Economic Decline analysis. Each entry includes suburb name, postcode, IRSAD decile, region, 5-year growth rate, risk reason, and severity classification.

Key Findings

• IRSAD Crossover Effect — IRSAD decile 9–10 suburbs with under 20% 5-year growth where high socio-economic standing has stalled capital appreciation
• Friction Ceiling — IRSAD decile 8 suburbs with under 10% 5-year growth approaching the ceiling where socio-economic advantage plateaus with severely limited upside
• Socio-Economic Decline — Suburbs where IRSAD decile dropped 1+ since 2018 AND delivered under 5% 5-year growth, signalling structural deterioration
• 52 Critical Suburbs — Negative 5-year growth, meaning capital loss territory
• 161 High-Risk Suburbs — Under 10% 5-year growth, severe underperformance relative to market
• 213 Elevated-Risk Suburbs — Under 20% 5-year growth, below market average
• 426 No-Go Suburbs — Full register across all Australian states and territories
