Analysis of information support in the context of establishing a mass appraisal system for land in Ukraine

The aim of this work is to analyze the compliance of the information indicated in existing state registers and databases with the requirements set for automated mass appraisal systems of real estate, according to the standards adopted by the International Association of Assessing Officers (IAAO), and the possibility of applying various methodological approaches to appraisal. To achieve the research objective, the following methods of scientific inquiry were applied: monographic, analysis, and synthesis. The monographic method was used to study scientific works dedicated to the introduction of mass appraisal systems in Ukraine and worldwide. The analysis method was employed to study existing registries, databases, standards, methodologies, and recommendations for the construction of such systems, as well as limitations regarding their application in Ukraine. The synthesis method justified the need for the introduction of a modern cadastral system and highlighted shortcomings in the content and methodology of maintaining existing state registers containing information about real estate objects in Ukraine. As a result of the analysis, it was found that, overall, the aggregate information available in various sources, databases, and registers is sufficient for conducting mass appraisal of non-improved land parcels. At the same time, the authors highlight the issue of the lack of a unified information exchange system, the implementation of which would enable the use of existing information. Additionally, the limited ability to use existing registers for implementing income and cost-based methodological approaches applicable to improved land parcels is emphasized. The scientific novelty and practical significance lie in highlighting the possibilities and feasibility of using the existing State GeoCadastre database as a basis for a future mass appraisal system, as it indirectly affects the values specified in the state register of property rights to real estate.
