Valuation data encompasses the methods, models, and comparable sales data used to estimate a property's current market value. The Automated Valuation Model (AVM) is the dominant product in this space — a statistical algorithm that estimates value based on recent comparable sales, property characteristics, and market conditions. AVMs are used by mortgage lenders for quick risk assessments, by investors to screen deals at scale, and by consumers to check their home's worth. This category also includes traditional appraisal data and broker price opinions (BPOs).

HouseCanary
Institutional-grade AVM with confidence scores, comps, and rental value estimates.
CoreLogic (Cotality)
Enterprise AVM used by major mortgage lenders and insurance companies.
Zillow
Consumer-facing AVM covering 110M+ US properties, updated weekly.
Always review the AVM confidence score alongside the estimate. Low-confidence scores (below 70%) indicate sparse comparable sales data and high value uncertainty.
AVMs are fast and scalable but lack physical inspection. For high-value or unusual properties, a traditional appraisal or BPO provides a more reliable valuation.
