In real estate, property AVM (Automated Valuation Model) is used to estimate a property value typically during the underwriting process when appraisals are needed. AVMs are also used on websites to provide property estimates for potential sellers, which in turn, become valuable leads.

Whatever your reason for using AVMs, many factors go into the calculation of an AVM — and more data is not always better.

“What we exclude is important,” said Clifford A. Lipscomb, vice chair and co-managing director with AVM Analytics, a company that has developed several AVMs. “Not only do we exclude certain anomalous property types, but we also exclude the subject property itself, making our monthly accuracy tests a true out-of-sample comparison.”

In other words, clean, targeted data means more accurate property AVM calculations.

Let’s take a broader look at several AVM companies in the real estate industry.

ATTOM AVM – ATTOM Data Solutions

Robust database with 38 million transactions, tax assessment, liability information, recent home sales, market insights and more create an informed, data-driven property AVM estimate.

  • Valuations for over 80 million homes across the U.S., covering 2,194 counties, containing 98 percent of the U.S. population.
  • Multiple modeling approaches – statistical, metrics derived, and value blending.
  • Built-in accuracy measures eliminate outliers from the start and increases model effectiveness.
  • Rigorous comparable properties for accurate property value estimates.

“The new ATTOM AVM fills an important gap in the world of property valuation products that primarily reside on one of two extremes: overpriced lender-grade AVMs that are only cost-effective for a select few giant corporations; and free AVMs available to the masses but diluted due to their inherent need to be all-inclusive — not to mention they are typically not available to be delivered in bulk,” said Rob Barber, CEO with ATTOM Data Solutions. “The ATTOM AVM targets the big middle between those two extremes, providing the marketplace with a lender-grade AVM delivered via bulk data delivery platforms that are flexible and cost-effective.”
