Retrospective Appraisal


A Retrospective Appraisal, also known as a Historical Appraisal or Retrospective Valuation, is a type of appraisal conducted to determine a property’s value as of a specific date in the past. It is typically used in situations where the value of a property at a certain point in time is needed for legal or financial purposes, such as in eminent domain cases, insurance claims, or historical preservation projects.

A Retrospective Appraisal provides an opinion of value with an Effective Date in the past. It is often used in connection with Appraisal Expert-Witness testimony and requires highly-trained—highly-skilled—highly-credentialed discipline-specific and multidisciplinary appraisers with decades of experience that are specifically trained and accredited in providing Retrospective Appraisals and in developing and reporting differing opinions-of-value, rebuttal appraisals, and appraisal expert-witness testimony.

The retrospective appraiser will use research and analysis of past market data, including sales of similar properties, and economic conditions at the time of the appraisal, to determine the value of the property as of the date in question. The appraiser will also consider the condition of the property, any physical changes that have occurred, and any other relevant factors that would have affected the value at that time.

Retrospective appraisals can be challenging as they require the appraiser to have a thorough understanding of historical market conditions and trends, as well as the ability to research and analyze historical data. The appraiser will typically have to consider the availability and reliability of historical data, which can be limited, and may need to make some assumptions or estimates in order to complete the appraisal.

Retrospective appraisals are important in some legal cases where the property value at a specific point in time is needed for the decision-making process, such as in eminent domain cases, insurance claims, and historical preservation projects.
