Freddie Mac's Home Value Calibrator

Home Value Calibrator® (Calibrator) is a quality control tool that measures the risk that an appraisal, or other estimate of a property value, exceeds the actual market value by at least 10 percent. It assists in identifying loans for further evaluation and prioritizing workflow. Calibrator combines the precision of an Automated Valuation Model (AVM) with a statistically based scoring model to deliver a score that can help identify loans with potentially inflated collateral valuations.

Lender Benefits

Calibrator is more efficient than traditional quality control methods, and can help you:

  • Match the level of underwriting review to the risk identified.
  • Identify potential appraisal outliers prior to funding.
  • Prioritize workflow.
  • Streamline quality control sampling methodology.
  • Improve assessment of valuation quality by identifying production at channel or branch level.

How It Works

  • Leverages the AVM combined with a statistical scoring model.
  • Analyzes several key elements of loan data and property information.
  • Generates a score between 300 and 900 to indicate the probability of an inflated value that may be used to prioritize workflow.
  • Indicates whether the purchase price, estimate of value, or appraisal value might be inflated. Lower scores indicate a higher risk.
  • Allows you to produce customized monthly aggregated reports to identify trends.

Interpreting Calibrator Scores
