Real estate appraisal is a complex process requiring accuracy and skill to estimate property value objectively and realistically. This chapter, "Defining the Problem, Preliminary Analysis, and Data Collection," is a cornerstone of this process, establishing the scientific and methodological foundation for appraisal.
The scientific importance of this topic lies in it being the first crucial step towards accurate and reliable real estate appraisal. A clear and precise definition of the appraisal problem, followed by a comprehensive preliminary analysis, guides data collection and defines its scope. This scientific approach ensures that the appraisal process focuses on the factors most influential on property value, avoiding deviations or omissions that may negatively affect the final result. Furthermore, understanding different data sources and how to collect and analyze them systematically contributes to building a real estate appraisal based on verifiable and factual evidence.
This chapter covers the essential initial stages in the real estate appraisal process. It begins by clearly defining the appraisal problem, including identifying the property to be appraised, defining the property rights involved, the date of valuation, the value standards used, and the purpose of the appraisal. It then moves to the preliminary analysis phase, where the necessary data to solve the appraisal problem is identified, the sources of this data are determined, the available resources are evaluated, and an action plan and timeline for implementing the appraisal process are developed. Finally, it addresses the data collection phase, reviewing different types of data (general and specific, primary and secondary), their diverse sources, and methods for collecting and evaluating them.
