AVM Accuracy in 2025
The best AVMs now achieve median error rates of 2-3% in well-covered urban and suburban markets. However, accuracy varies significantly by data availability and property type.
How AVMs Work
Modern AVMs combine comparable sales analysis, hedonic regression modeling, and machine learning. Advanced models like Quantarium also incorporate satellite imagery and computer vision for additional accuracy.
Accuracy by Market Type
- Urban/suburban with good data: 2-3% median error — reliable for listing discussions
- Rural with limited data: 7-10% error — use as a starting point only
- Non-disclosure states: 5-8% error — tax assessment data may be outdated
- Unique or custom homes: 8-15% error — lack of comparable sales
When You Can Trust an AVM
AVMs are reliable for listing price guidance, buyer consultations, market trend analysis, and portfolio monitoring. They should NOT be the sole method for mortgage approval, estate settlement, or luxury properties without comparables.
