Technical Terms Glossary

To ensure a professional appraisal report, it is vital to understand these international methodology pillars:

• Replacement Cost New (RCN): The current cost of constructing a structure of similar utility using modern materials and labor standards, without considering depreciation.
• Age Depreciation (Ross Curve): Unlike straight-line depreciation, the Ross curve acknowledges that a building does not lose value linearly. It uses a parabolic curve that reflects higher value loss as the asset approaches the end of its life cycle.
• Physical Condition (Heidecke Matrix): A coefficient that adjusts value based on maintenance and physical integrity. This factor accounts for the fact that a well-maintained old building can be worth more than a neglected newer one.
• Estimated Useful Life: The period during which a structure is expected to remain functionally useful. For reinforced concrete structures, global standards typically range between 60 and 80 years.
• Depreciated Replacement Cost (DRC): The final result representing the building's value today after deducting physical wear and age-related obsolescence.
