Model Documentation
Built for Precision and Clarity
The Chimney Confidence Score ensures that home value estimates are backed by robust validation and statistical accuracy.
Advanced Scoring Methodology
Score Range: The confidence score falls within a predefined scale (e.g., A–F or High–Low), helping users quickly interpret valuation reliability.
FSD (Forecast Standard Deviation): A statistical measure that indicates the expected variation in the AVM estimate. A lower FSD means higher confidence.
Factors Affecting Confidence Scores
Market Data Availability: More recent and comparable sales data increase accuracy.
Property-Specific Attributes: Unique or uncommon homes may have lower confidence due to limited comparable sales.
Local Market Volatility: Rapid market shifts can impact valuation consistency.
Comprehensive Coverage
Confidence scores apply to all residential properties covered by the Chimney Estimate, ensuring clarity for homeowners across diverse property types.
Use Cases & Applications

Homeowners can better understand how reliable their estimated home value is before making financial decisions.
Lender & Financial Institution Support
Lenders can assess valuation strength when considering loan-to-value (LTV) ratios and mortgage applications.
Real Estate & Market Analysis
Institutions can use aggregated confidence scores to evaluate regional property trends and investment risks.
Limitations and Best Practices
Not a Guarantee: A high confidence score does not replace an appraisal but serves as an additional data point for decision-making.
Interpreting Scores: Users should consider market trends and property conditions when reviewing their valuation confidence.
