Understanding the Data


ATTOM uses its unique property identifier - ATTOM ID as a way of combining this data with other property data ATTOM makes available. The ATTOM ID can be used to combine the Home Equity data with Address data to get information such as the street address of the property. The ATTOM ID can also be used to combine the Home Equity data with Current Owner data to get information about the current owners of the property.

Home Value

The AVM data used to establish the home equity is not included as part of Home Equity.

Amortized Loan Balance

ATTOM keeps track of up to three individual active loans secured by the property that are deemed to occupy the first, second, and third positions against the property. The loan positions are derived as part of the loan model. Based upon the known characteristics of each loan, ATTOM is able to estimate the amortized loan balance of each loan and from that the total loan balance, including the combined loan to valuation (CLTV).

Home Equity

The estimated home equity for the property is based on the home value (AVM) and estimated amortized loan balance.
