Reconciliation and Final Value Opinion

Chapter 11: Reconciliation and Final Value Opinion

I. Introduction

The cost approach, while providing a systematic methodology for estimating value, often yields a different value indication than other appraisal approaches, such as the sales comparison or income capitalization approaches. The reconciliation process is crucial for synthesizing these disparate value indicator❓s into a single, credible opinion of value. It is the critical step where the appraiser analyzes the strengths and weaknesses of each approach and arrives at a final conclusion. This chapter explores the science and art of reconciliation, providing a detailed framework for appraisers to develop well-supported and defensible value opinions.

II. Defining Reconciliation

• A. General Definition: Reconciliation is the process of critically examining the value indications derived from two or more appraisal approaches (e.g., cost, sales comparison, income) to arrive at a final, single value opinion or a range of values.

• B. Context within the Cost Approach: Specifically, it involves integrating the value indication from the cost approach with value indications from other approaches, considering their relative reliability and applicability to the subject property and assignment.

• C. NOT Averaging: Reconciliation is not a simple mathematical averaging of value indicators. It is a qualitative analysis driven by the appraiser’s professional judgment and experience.

III. Scientific Principles and Theories Underlying Reconciliation

• A. Decision Theory: Reconciliation can be framed within the context of decision theory, where the appraiser weighs the evidence (value indicators) and chooses the most likely accurate value based on available information.

  • 1. Expected Value: While not directly calculated in reconciliation, the concept of expected value (EV) is relevant. If V_i represents each value indicator and P_i represents the appraiser’s estimated probability (or confidence) in that indicator, the expected value could be conceptually expressed as:

    EV = Σ (V_i * P_i)
    Where Σ represents the summation across all value indicators.

  • 2. Risk Assessment: Each value indicator carries an inherent risk of being inaccurate. The appraiser’s job is to identify and minimize this risk by carefully evaluating the data and methodology used in each approach.

• B. Statistical Analysis: While averaging is avoided, the principles of statistical analysis inform the reconciliation process.

  • 1. Sample Size: A value indicator based on a larger, more representative sample of data is generally more reliable.
  • 2. Variance: The spread of data points around the mean influences the reliability of an indicator. Lower variance suggests higher precision.
  • 3. Confidence Intervals: Appraisers often implicitly consider confidence intervals. They acknowledge that the true value likely falls within a range, not a single point.

• C. Hierarchy of Evidence: Different types of data hold different weights. Direct, verifiable market data (e.g., comparable sales) is typically given more weight than less direct evidence (e.g., subjective estimates of depreciation in the cost approach).

IV. Factors Influencing the Reliability of Value Indicators

• A. Amount of Data:

  • 1. Statistical Significance: Value indicators based on larger datasets or derived from more detailed data❓ are generally considered more reliable because they are less susceptible to random errors or outliers.
  • 2. Multiple Sources: Indicators corroborated by independent sources are preferred.

• B. Accuracy of Data:

  • 1. Verification: The extent to which data has been verified is critical. Verified sales transactions, confirmed cost data, and substantiated income figures increase reliability.
  • 2. Precision: The level of precision in the data must be considered. Highly precise data (e.g., detailed cost breakdowns) may be more reliable, but only if they are accurate.

• C. Relevance of Data:

  • 1. Assignment Terms: The value indicator must align with the purpose❓ and intended use of the appraisal (e.g., market value vs. investment value).
  • 2. Appropriateness of Technique: The appraisal technique used must be suitable for the property type and market conditions. For example, the income approach may be irrelevant for a property not typically rented.
  • 3. Market Participants: The motivations and actions of market participants must be understood. Are they typical buyers and sellers, or are there unique circumstances influencing their behavior?

V. Practical Applications and Experiments

• A. Experiment: Consider a single-family residence valued using the cost approach, sales comparison approach, and income approach.

  • 1. Cost Approach: The value indicated is \$300,000. The appraiser used a recognized cost service but had difficulty accurately estimating depreciation due to the property’s unique features.
  • 2. Sales Comparison Approach: The value indicated is \$320,000. This was based on three comparable sales, all within a half-mile radius and sold within the last three months. Adjustments were carefully made for differences in size, condition, and features.
  • 3. Income Approach: The value indicated is \$280,000. This approach was based on limited rental data and required significant assumptions about vacancy and operating expenses.
  • 4. Reconciliation: The appraiser would likely give the most weight to the sales comparison approach because it is based on direct market data and required fewer subjective assumptions. The cost approach provides support for the value range, while the income approach is given less weight due to its limited data and assumptions. The final value opinion might be \$318,000, slightly below the sales comparison indication but supported by the other approaches.

• B. Scenario Analysis: In a rapidly changing market, the appraiser might perform a sensitivity analysis to determine how changes in key assumptions (e.g., discount rates, rental growth) would affect the value indication from the income approach. This helps assess the robustness of the final value opinion.

VI. Mathematical Considerations

• A. Sensitivity Analysis:

  • 1. Formula: Consider a simplified discounted cash flow (DCF) model:

    PV = CF1 / (1 + r) + CF2 / (1 + r)^2 + TV / (1 + r)^2

    Where:

    PV = Present Value
    CF1 = Cash Flow in Year 1
    CF2 = Cash Flow in Year 2
    TV = Terminal Value (estimated sale price at the end of Year 2)
    r = Discount Rate

  • 2. Sensitivity: The appraiser can systematically vary the discount rate r and terminal value TV to observe how the present value PV changes. This reveals the sensitivity of the income approach to changes in these key assumptions.

• B. Statistical Weighting (Conceptual):

  • 1. Formula: While not directly used in reconciliation, the idea is to assign weights based on confidence levels:

    Value Opinion = (Weight1 * Value1) + (Weight2 * Value2) + (Weight3 * Value3)

    Where Weight1 + Weight2 + Weight3 = 1

  • 2. Application: The appraiser subjectively assigns weights based on the reliability factors discussed earlier. For example, if the Sales Comparison approach is deemed most reliable, it might receive a weight of 0.6, while the Cost and Income approaches might receive weights of 0.2 each.

VII. The Final Value Opinion

• A. Point Estimate: The appraiser’s final value opinion is typically expressed as a single dollar amount (point estimate).

• B. Range of Value: In certain situations, particularly when uncertainty is high, a range of values may be appropriate, but must be adequately supported and explained.

• C. Rounding: Value opinions should be rounded to a level of precision that reflects the accuracy of the underlying data and analysis (e.g., rounding to the nearest \$1,000 for a residential property).

VIII. Quality Control: Ensuring Understandability

• A. Clarity of Explanation: The appraiser should ensure that the reasoning behind the reconciliation process is clearly explained in the appraisal report, in a manner understandable to a non-appraiser reader.

• B. Defensibility: The value opinion must be well-supported by the evidence and analysis presented in the report, making it defensible in a critical review or legal challenge.

IX. Conclusion

Reconciliation is a vital step in the cost approach, requiring a blend of scientific rigor and professional judgment. By carefully considering the reliability and relevance of each value indicator and by providing clear, well-supported reasoning, appraisers can develop credible and defensible value opinions that meet the needs of their clients and the standards of the profession.
