iKey Facts
- •AVMs (Automated Valuation Models) are now standard for residential and commercial stabilised assets
- •Major lenders (CBA, NAB, ANZ, Westpac) use AVMs for 60-80% of residential loan-decisioning
- •Development sites remain a poor fit for current AVMs — too few comparables, too many planning variables
- •AI-assisted feasibility models (Estate Master + ML overlays) emerging for institutional development analysis
- •See companion: How Developers Assess Feasibility Before Buying Land
What AVMs Do
Automated Valuation Models ingest:
- Recent comparable sales
- Property attributes (bedrooms, area, age, condition)
- Market trends (CoreLogic, RP Data, Domain)
- Geospatial features (distance to schools, transit, employment)
They output an estimated value with confidence interval.
For stabilised residential and commercial, AVMs are now accurate enough that major lenders pre-approve loans without manual valuation in 60-80% of cases.
Where AVMs Struggle
Development sites are a poor fit because:
- Few directly-comparable transactions (each site is unique)
- Planning variables dominate (zoning, height, plot ratio, overlays)
- Feasibility is context-dependent (developer type, capital stack, builder)
- Demand is buyer-specific (institutional vs mid-tier vs boutique)
- Time horizons differ (BTS 2-3yr, BTR 15-25yr)
AVMs typically miss development-site values by 15-40% vs realised transaction prices.
AI-Assisted Feasibility
"What This Means for Vendors Vendors using only AVM-based valuations risk under-pricing development sites by 20-40%."
Speak with our team
ACRES provides expert property advisory across Australia.
Emerging tools combine traditional Estate Master / Argus models with ML overlays:
- Auto-populate construction costs from current builder data
- Predict pre-sale rates from recent project data
- Sensitivity-test inputs at scale (Monte Carlo simulation)
- Flag feasibility outliers (input combinations unlikely to support feasibility)
Institutional buyers (Cbus, Mirvac, GPT) are early adopters. Mid-tier developers still mostly use traditional models.
What This Means for Vendors
Vendors using only AVM-based valuations risk under-pricing development sites by 20-40%.
For development sites, vendors should:
- Engage a specialist advisor with current transaction data
- Run a counter-feasibility (developer-perspective model)
- Use AVMs only as a sanity check on residential value
The Next 5 Years
Likely developments:
- AVMs improve on stabilised property accuracy (+5-10% precision)
- Development-site AVMs remain limited
- AI-assisted feasibility becomes mainstream institutional tool
- Lender appetite for AVM-only decisioning grows
- Independent valuers compete with AVMs on borderline assets

Frequently Asked Questions
Can I trust an AVM estimate of my development site?
No — AVMs miss development value by 15-40%. Use specialist advisor instead.
Are banks using AVMs for development site loans?
Rarely — development sites still get manual valuation in nearly all cases.
Will AI eventually price development sites accurately?
Improvement is likely but full accuracy is far off due to planning and feasibility variables.
