description The Sales Comparison Method (SCM) is the most widely used method of property valuation; particularly for residential properties. With transaction data becoming more and more accessible, the trend of using Comparison Method will continue; the valuation of commercial properties is expected to also use this method. However, SCM is criticised for its subjectivity with inconsistent prediction; SCM procedure relies too much on the expert judgment of the valuer such that the value of property varies between valuers. This paper puts forward a proposal for an alternative technique using SCM that will minimise subjectivity in property value prediction with reduced complexity. The aim of this research is to develop a formal automated procedure of the Sale Comparison Method for double storey terrace house. The conceptual procedure was developed by examining peer research, Malaysian Valuation Standard, a standard in use throughout the Valuation and Property Services Department in Malaysia.
