Methodology
How HIDD produces district ratings.
Area Compare is a screening view of neighbourhood-level evidence. This page sets out what informs the ratings, how the scale works, when the data was assessed, and what the comparison cannot tell you.
01
Data sources
Evidence reviewed for each district
The exact documents and observations available differ by district. HIDD draws from the following evidence groups and records district-specific supporting notes in each neighbourhood brief.
Physical and environmental evidence
Observed or documented drainage, flood and coastal exposure, road access, utilities, infrastructure, pollution, erosion and nuisance conditions.
Market evidence
Available demand, resale, pricing-support and absorption evidence used to assess how readily property in the district may trade.
Local operating context
Available safety information, access-control conditions and other location-specific observations relevant to day-to-day ownership.
Professional review
HIDD reviews the available evidence and records the supporting assessment notes, analyst and applicable assessment date for each district.
02
Scoring dimensions
Seven factors, one fixed scale
Each factor is assessed from 0 to 100 in risk direction: a higher stored score means greater concern. The scale is always fixed at 0–100 and never expands or contracts to fit the districts currently selected.
0–34Low risk
35–54Mid risk
55–100High risk
Flooding
Flood exposure, drainage conditions, and coastal pressure.
Title Complexity
Ownership records, document consistency, and title concerns.
Planning & Zoning
Land use, building approvals, zoning, and demolition exposure.
Infrastructure
Road access, utilities, drainage, and other essential infrastructure.
Security
Safety conditions, access control, and local security concerns.
Environmental
Noise, pollution, erosion, and other environmental concerns.
Market Liquidity
Buyer demand, pricing support, and how easily a property may be resold.
03
Data collection dates
The date belongs to the rating
Ratings describe the evidence available at the date shown. Every comparison and district brief displays its applicable date; it should be considered part of the rating, not a footnote.
04
Update frequency
Rolling review, not live monitoring
District assessments are reviewed on a rolling basis and may be updated when HIDD identifies material new evidence. They are not real-time feeds. Before relying on a rating for a transaction, check its displayed date and request a current, property-specific assessment where the timing or exposure matters.
05
Limitations
What Area Compare does not establish
- A district rating does not determine the condition, title or value of a particular property.
- Conditions can vary materially by street, estate, building and date.
- Available records may be incomplete, delayed, disputed or changed after assessment.
- The radar shape is a comparison aid and must not be read as a probability or forecast.
- Area Compare does not replace inspection, legal due diligence, valuation or transaction-specific risk review.
