To provide the most transparent measure of variability in the estimates, we provide the larger of differences between the low and high value and point estimate.

FREE WHITE PAPER
ATTOM provides transparency in its analytical process by offering a FREE detailed white paper, better explaining how the ATTOM AVM works. This white paper provides insights into the data sources, algorithms, and methodologies used to calculate property valuations.
The ATTOM AVM is an advanced automated valuation model (AVM) designed to provide hyperlocal valuations using transparent and robust statistical procedures. The ATTOM AVM uses comparable sales based on geographic areas to estimate the value of a property using multiple valuation models. Statistical metrics and clustering algorithms are used to eliminate certain models, and the confidence score is determined by the difference between the low and high values and the median value estimate. Regular accuracy tests are conducted to determine the most accurate model for each neighborhood, with the most accurate local model becoming the estimated AVM value.
