Which method is often used by appraisers as a checking mechanism for estimated construction costs?

The indexing method is frequently employed by appraisers as a way to verify estimated construction costs. This method involves using established cost indices to adjust historical cost data to current prices. By applying the index—often derived from various sources that track changes in construction costs over time—appraisers can check and validate their construction cost estimates against reliable, up-to-date benchmarks.

This approach helps ensure that the estimated costs reflect current market conditions, rather than overly relying on outdated figures. It provides a useful reality check on the appraiser's assumptions regarding construction expenses, ensuring greater accuracy in the property valuation process. Using the index method, appraisers can obtain a clear and actionable reference point for estimating costs, which is essential in accurately assessing a property's value in the context of the local real estate market.
