Abstract
<jats:p>The article examines international experience in the formation and functioning of mass appraisal systems using the examples of selected countries. The selected countries include the United States and Sweden, where mass appraisal systems have been successfully operating for several decades, as well as Lithuania and Slovenia, where mass appraisal systems were introduced relatively recently, at the beginning of the 21st century. A comparative analysis and generalization of the main aspects of mass appraisal systems in the selected countries are conducted. In particular, the article addresses legislative regulation of mass appraisal, management of the mass appraisal process (in terms of the distribution of functions and powers among key stakeholders), consideration and analysis of input data related to the economic and physical-technical characteristics of real estate objects, as well as the application of valuation approaches and methods in the appraisal of specific types of real estate.</jats:p>
