銀行採用簡約估價模型於房貸擔保品重估作業自動化之研究

A Study on the Application of Simplified Appraisal Model for the Revaluation of Bank's Residential Mortgage Collateral

指導教授 : 林修葳

摘要


不動產鑑價是繁瑣和費時的工作,銀行對新申貸或增貸的客戶,多數找專業不動產鑑價師,委外人工處理,由於數量不大,銀行尚能接受,但如針對銀行現有幾萬筆不動產的擔保品,每年均以新申貸的方式人工重估,在成本和人力的考量下,實務上不可能做到。本文目的在於探究住宅不動產電腦大量估價的背景、理論方法、評估標準與配套機制,以及成熟的大量估價模式對金融機構效益之說明,同時借鑒專業住宅不動產鑑價方法,嘗試設計一套銀行內部不動產擔保品價值重估簡約模型,並提供配套的評估規則、相關調整方式和檢核機制,以確保重估結果的品質。期能在銀行不動產重估的作業上,提供經濟可行的方案。最後討論實務應用上尚待進一步溝通問題和相關配套系統的建置需求建議。銀行如能有效掌握不動產價值與價格,做好不動產擔保品管理與擔保品鑑價重估相關之內稽內控,或能顯著俾益金融體系與整體經濟。同時相關不動產價格資訊,也可以用來協助產業界評估未來不動產市場的變化趨勢。

Real Estate Appraisal is typically a tedious and time-consuming task. Generally, for a new loan application or a request for the increase of a credit line, bank will look for an external professional property appraiser. As to the revaluation of existing mortgage collaterals, with thousands of existing real estate collaterals, substantial efforts may be required to complete the task. Outsourcing the task or valuating each individual property manually become infeasible. The purpose of this study is to investigate a simplified property valuation model, providing certain economically viable solutions to automate the revaluation process for the large number of residential real estates and to establish a checking system to ensure the quality of the revaluation processes. Revaluation of real estate property is crucial in bank loan operation and collateral management. If a bank effectively measures the collateral value and price, it may better control the relevant risk and in turn, enhance soundness and stability of the financial system and the overall economic environment. While real estate prices related information may also be used to help assess future industry trends in the real estate market.
