Abstract: Traditional approaches to estate valuation rely heavily on the manual judgment of professional valuers applying the comparative, investment, residual, cost, and profits methods to sparse and often outdated transaction records. This dependence introduces subjectivity, slows turnaround time, and limits reproducibility, particularly in property markets where sales data is fragmented across registries, agencies, and informal records. An accurate, dependable, and efficient valuation system would result from a well-managed estate valuation model. It also aids in re-establishing property owners' privacy. The goal of this study, which focuses specifically on estate valuation in the context of a property and investment company, is to determine how different classes of properties are valued in order to create a computerized model that will solve the issues encountered throughout the valuation process. Additionally, it aims to reduce operational bottlenecks by providing computer-assisted alternatives to the establishment's manual property valuation process. In light of this, we made the decision to create an Estate Valuation Modeling System (EVMS), understanding that doing so would essentially solve a number of issues related to the establishment's current manual operating system. Java 8.0 was the programming language utilized to create this system. Results indicate that the model's estimates fell within an acceptable margin of the manually derived values for the majority of test properties, with a coefficient of dispersion within the range recommended by international mass appraisal standards.
