How is the NPI typically calculated?

The NPI, or National Property Index, is commonly calculated based on appraised property values. This method provides a more accurate reflection of the current real estate market by assessing the worth of properties as determined by professional appraisers, rather than relying on price trends or predictions that may not accurately depict the actual market conditions. Appraised values take into account various factors such as location, property condition, comparables, and other market dynamics, which contribute to a comprehensive valuation.

Using appraised property values helps in mitigating fluctuations that might otherwise skew the index if based solely on sales prices, predictions, or historical data that do not consider the present state of the market. Thus, utilizing appraisals ensures a more consistent and reliable methodology for calculating the NPI.
