iKey Facts
- •CoreLogic and Domain offer algorithmic comparable analysis to lenders, agents, and consumers
- •Algorithms weight: location, size, age, condition, sale date, market trend
- •Accuracy is high for standardised residential (within 5-8%), low for non-standard development
- •Specialist comparable analysis remains essential for $5m+ development sites

How Algorithmic Comparables Work
Major providers (CoreLogic, PriceFinder, Domain, REA) aggregate every settled property transaction in Australia. Their algorithms:
- Filter to nearby properties (distance, suburb)
- Score similarity (size, age, condition, features)
- Weight by recency and quality
- Output an estimated value range
This is mature technology — typical residential AVM accuracy 5-8% MAE (Mean Absolute Error) within 0-12 months of sale.
Where Algorithmic Comparables Excel
- Standardised residential (typical houses, apartments)
- Stabilised commercial with comparable lease
- High-volume markets (Brisbane inner-middle suburbs)
- Recent transaction periods (less than 18 months back)
Where They Fall Short
- Development sites (planning variables dominate)
- Premium / unique properties (no comparables exist)
- Thinly-traded segments (industrial, healthcare, hospitality)
- Long-held land (cost base / capital gains complexity)
- Land-only sales (improvements distort algorithms)

Vendor Strategy
For residential sale: algorithmic comparable as first reference + agent sanity-check.
For development site: specialist advisor with manual comparable analysis. Algorithm output useful as one data point only.
What's Coming
PropTech is improving in two directions:
- More data — better cleanliness, more recent, more attributes
- Better models — large-language-model integration for narrative explanations
Within 3-5 years, AI-explained comparable analysis will be standard. But human judgment on development sites will remain superior for another decade.

Frequently Asked Questions
Is CoreLogic accurate for my development site?
Probably not. CoreLogic algorithms struggle with non-standard, unique, or planning-dependent properties.
Can I trust the Domain estimate online?
As a rough guide for standard residential, yes. For development land, no.
How often do algorithmic estimates miss?
For development sites, 15-40% miss is typical. For residential, 5-10%.
