What is 累计折旧?
房产价值自建成或购置以来已发生的总价值损耗，包括物理磨损、功能老化和外部经济因素。评估时需从重置成本中扣除，是成本法估价的核心要素。
Description
Accrued depreciation represents the difference between a property's replacement cost as new and its current market value. It captures all forms of value loss that have accumulated since the building was constructed. Appraisers use this concept when valuing property under the cost approach.
Physical deterioration: Wear and tear from age, weather, and use, including cracked tiles, aging HVAC systems, and corroded plumbing.
Functional obsolescence: Outdated design features that reduce desirability, such as small rooms, insufficient parking, and lack of modern amenities.
External (economic) obsolescence: Value loss from factors outside the property, such as new highway traffic, declining neighborhood conditions, or zoning changes.
A Dubai Marina apartment has a replacement cost of AED 2,500,000. Physical deterioration (15 years of wear) accounts for AED 375,000. Functional obsolescence (outdated kitchen and bathrooms) adds AED 150,000. External factors are neutral. Total accrued depreciation = AED 525,000. Appraised value under cost approach = AED 2,500,000 - AED 525,000 = AED 1,975,000 (plus land value).
In Dubai's relatively young property market, physical deterioration is a significant concern given the harsh climate. Extreme heat, humidity, and sandstorms accelerate wear on building exteriors and mechanical systems. Properties built in the 2005-2010 boom era are now 15-20 years old, and accrued depreciation is becoming an important factor in valuations, particularly for older buildings competing with newer inventory.
公式
Accrued Depreciation = Replacement Cost New - Current Appraised Value of ImprovementsOliva 如何运用
Oliva's property scoring algorithm factors in building age and the condition assessment of developments it features. Properties showing significant accrued depreciation relative to their asking price are flagged for review, ensuring investors have a realistic view of the condition risk embedded in any opportunity.
How to interpret
Accrued depreciation is most relevant when evaluating older properties using the cost approach to valuation. If the market comparison approach (using comparable transaction prices) points to a value notably below replacement cost, the difference is often explained by accrued depreciation. Understanding which type of depreciation is causing the gap tells you whether it is curable through renovation or structural.
Investors targeting value-add strategies deliberately seek properties with curable accrued depreciation: functional obsolescence from outdated kitchens and bathrooms, or physical deterioration from deferred maintenance. If the renovation cost is less than the value it adds, the investment makes sense. External obsolescence, by contrast, cannot be fixed by the investor, so properties suffering from it require a much larger price discount to justify acquisition.
迪拜市场背景
Dubai's extreme climate accelerates physical deterioration at a faster rate than temperate markets. Air conditioning systems, exterior facades, and building mechanical systems all degrade faster in conditions of extreme heat, humidity, and sandstorms. Buildings constructed during the 2004-2010 boom era are now 15-20 years old, and some show significant physical deterioration, particularly where maintenance has been deferred due to low service charge collection or management disputes.
Functional obsolescence is increasingly visible in older Dubai buildings. First-generation residential towers in areas like International City, Dubai Sports City, and parts of JBR lack features that newer buildings consider standard: smart home connectivity, electric vehicle charging infrastructure, co-working spaces, and modern lobby finishes. This functional gap creates pricing pressure on older stock as buyers and tenants increasingly favor newer developments.
Frequently asked questions
The total accumulated loss in a property's value from all causes, physical deterioration, functional obsolescence, and external obsolescence, measured from the time of construction to the date of appraisal.
The standard formula is: Accrued Depreciation = Replacement Cost New - Current Appraised Value of Improvements. Applying it consistently lets you compare projects on a like-for-like basis, which is the point of the metric.
