Gaining a True Understanding of a Home’s Value

Simply put, a home’s equity is the difference between its current market value and the remaining debt owed on its mortgage. While it’s a simple calculation to make, keeping track of home equity for assessing the value on a portfolio of homes or for gaining critical insight into a local market, isn’t quite as easy. That’s where ATTOM Data Solutions comes in. With nationwide coverage for over 430 million loan transactions and a proprietary lender-grade AVM, ATTOM Data Solutions is able to calculate home equity for millions of properties nationwide.

How ATTOM Derives Home Equity Data

Equity in a home can increase or decrease over time depending on market forces that influence a home’s value and the rate at which a homeowner pays off the mortgage. To estimate a home’s current mortgage balance, ATTOM Data Solutions developed a loan model that enables the amortization of loans to give a more accurate home equity balance. ATTOM collects all active loans on a property, then creates an amortization schedule based on term and rates of the loan balance to get a true loan value. From there, we use our lender grade AVM to give us a more accurate estimated value on a home in today’s current market. Once that is complete, we compare a property’s AVM value to the estimated remaining balance to accurately estimate the equity of a specific property.
