About this report — Methodology & Data Sources
This property intelligence report was generated by the Effata Property Intelligence Engine, developed by Anthony Mamic at Mamic Real Estate, Brisbane. Reports are updated when new market data becomes available, typically within 48 hours of new sales settling.
Valuation methodology: The automated comparable market analysis (CMA) searches for agent-reported sales of the same property type within 1–1.5km over the preceding 12–18 months. Private sales and family transfers are excluded — only normal sales reported through licensed agents are used. Each comparable is scored for relevance (HIGH, MEDIUM, LOW) based on bedroom match, land area similarity (within 20%), proximity (under 800m), and recency (under 18 months). The final estimate uses a weighted formula: 60% HIGH-relevance comps, 30% MEDIUM-relevance comps, 10% all comps. Adjustments are applied at $800/m² for land area differences, $40,000 per bathroom, and $20,000 per car space.
Scoring methodology: Properties are scored across 10 dimensions (capital growth, rental yield, owner-occupier appeal, infrastructure, exit strategy, vacancy risk, management load, prestige, price fit, risk) each rated 1–5. The overall score is a weighted average. Deal ratings (Strong Buy, Buy, Hold, Avoid) are derived from the composite score and key risk factors.
Data sources: Sales data from PriceFinder (agent-reported sales only, excluding private sales). Flood overlays, zoning, and planning data from Brisbane City Council open data. Crime statistics from the Queensland Police Service (QPS) — rolling 12-month offence totals. Census data from the Australian Bureau of Statistics (ABS) 2021 Census. School locations from the Queensland Department of Education. Development applications from Brisbane City Council DA tracker.
