초록

부동산 감정평가(real estate appraisal)는 상당한 공익적 중요성을 지니는 위치에 서 있다. 그럼에도 과거와 현재의 조건 아래에서의 시장가치 의견(opinion of market value)을 중심에 두는 그 공식 이론(doctrine)은, 감정평가 산출물이 현대 금융 시스템에서 실제로 사용되는 방식과 점점 더 큰 긴장 관계에 놓이고 있다. 이 논문은 그 논거를 다섯 단계에 걸쳐 구축하며, 각 단계마다 명시적이고 질의 가능한 Prolog 지식베이스(knowledge base)를 함께 제시한다. 앞의 두 단계는 감정평가가 수행하는 사회적·경제적 기능을 확립하고, 세 번째 단계는 그 주된 최종 산출물인 시장가치 의견을 지목하며, 네 번째 단계는 계량적·금융적 예측(forecasting)에 견주어 감정평가가 지니는 시간적·방법론적 지향과 양자를 가르는 규제상의 경계를 살핀다. 이 논의들은 다섯 번째 단계의 중심 주장으로 수렴한다. 즉 주택담보대출에서 담보인정비율(loan-to-value ratio, LTV)로 조정된 시장가치는 장래 경매가치(foreclosure value)의 암묵적 대리지표(proxy)로 기능하는데, 이는 현재가치 이론이 인정하지 않는 미래지향적 용법이다. 많은 감정평가사(appraiser)는 이러한 담보평가상의 역할을 알지 못한 채, 그 역할이 요구하는 만큼 장래 가치 추세에 대한 주의를 기울여 시장가치를 다루지 않는다. 이 논문은 바로 그 문제를 드러내고 후속 연구를 촉구하고자 한다.
