Introduction: Defining the Appraisal Problem & Scope of Work
The real estate valuation process is a complex undertaking that requires a systematic and scientifically rigorous approach. A fundamental element in achieving accurate and reliable value conclusions is the clear and concise definition of the appraisal problem and the subsequent development of an appropriate scope of work. This chapter will delve into these critical initial stages of the valuation process, emphasizing their scientific importance in ensuring credible and defensible appraisal results.
The appraisal problem, at its core, represents the specific question the appraiser is tasked with answering. This necessitates the precise identification of the client and intended users, the intended use of the appraisal, the specific type of value sought (e.g., market value, investment value, insurable value), the effective date of the valuation, and all relevant characteristics of the subject property. Furthermore, it requires the explicit articulation of any assignment conditions that may impact the valuation, such as extraordinary assumptions, hypothetical conditions, or jurisdictional exceptions. Failure to accurately define the appraisal problem introduces significant uncertainty and can lead to flawed valuation conclusions.
Following the identification of the appraisal problem, the scope of work defines the specific procedures and analyses the appraiser will undertake to arrive at a credible solution. This includes determining the appropriate data to be collected, the extent of the data search, the methods of analysis to be employed (e.g., sales comparison, cost approach, income capitalization), and the level of inspection necessary. The scope of work must be sufficient to produce credible assignment results while adhering to the expectations of intended users and aligning with the accepted practices of competent appraisers performing similar assignments.
Scientifically, a well-defined appraisal problem and scope of work are essential for minimizing bias and maximizing the reliability and validity of the valuation. By explicitly stating the assumptions and limitations of the analysis, the appraiser promotes transparency and allows for critical evaluation of the resulting value opinion. The structured approach inherent in defining the problem and scope mitigates the risk of ad hoc decision-making and ensures a consistent and defensible valuation process.
The primary educational goals of this chapter are to equip students with the knowledge and skills necessary to:
1. Systematically identify and articulate all components of the appraisal problem.
2. Develop a scope of work that is appropriate for the complexity of the appraisal problem and compliant with relevant professional standards (e.g., USPAP).
3. Understand the scientific rationale behind a well-defined appraisal problem and scope of work and its impact on the credibility of the valuation.
4. Critically evaluate the appraisal problem definition and scope of work in appraisal reports.
By mastering these concepts, students will be well-positioned to conduct sound and defensible real estate valuations, contributing to the integrity and reliability of the property market.
