Property Data Used Makes a Difference

Our comprehensive database encompasses properties from all 50 states, covering 99% of the US population, and valuation software developed by Automated Valuation Model Analytics, our property AVM:

Employs multiple Real Estate AVM models to choose the modeling approach that is most accurate to the geographic area surrounding the individual property.

Uses the most accurate geocodes from various sources to pinpoint precise property locations while utilizing GIS boundary data for hyperlocal comparable selections.

Valuations are focused to only single-family homes, condominiums, and small multiple family properties (one-to-four units).

Harnesses a diverse range of comparable properties, seamlessly integrating the latest sales data to ensure an accurate representation of current market dynamics.

Confidence Matters

Every property receives a unique confidence score.

Our machine learning uncertainty model analyzes each property’s location and characteristics to predict property-specific valuation risk based on our historical prediction accuracy. This approach learns which factors are associated with higher or lower valuation precision, ensuring that each property’s confidence assessment reflects its individual risk profile.

Real Estate Portals

Displaying the most accurate estimated home values, along with detailed property profile information, adds up to page content that drives more traffic and higher conversion rates.

Create targeted prospect lists, where prospective market value is a key demographic filter. AVM values can also enrich all types of marketing collateral with recipient-relevant values.

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.
