About

HouseCanary's automated valuation model covers 136 million US properties, reporting a 2.7% median absolute error on post-close valuations and refreshing monthly. Its data API exposes current value with confidence bands, value analysis with comp context, and 36-month value forecasts.

Built for lenders, investors, and brokerages rather than consumers: access is API-first and enterprise-priced. AVMs can't see property condition or intangibles, so HouseCanary positions its output as one input to a valuation decision, not the decision itself.
