I. Introduction: The Scientific Foundation of Reconciliation in Appraisal

Reconciliation, in the context of real estate appraisal, is the culmination of the valuation process, bridging the gap between diverse value indicators to arrive at a single, well-supported opinion of value. This chapter delves into the scientific underpinnings of reconciliation, emphasizing its critical role in producing credible and defensible appraisals, vital for both Supervisory and Trainee Appraisers. This section will ensure work will pass muster in a critical review and not discredit the appraisers reasoning and conclusion. This section will give you the skills to send out sound and substantiated valuation reports!

• Reconciliation Defined: Reconciliation is the process of critically analyzing the reliability and relevance of multiple value indicators derived from different appraisal approaches or data sources to arrive at a final, singular opinion of value. This isn’t a simple averaging; instead, it’s a weighted analysis based on the scientific principles discussed below.

• Relation to the Course Description: This chapter directly supports the course description by:

  • Providing knowledge and skills essential for successful appraisal practice.
  • Reinforcing ethical considerations, ensuring the final opinion is unbiased and well-supported.
  • Elevating professional standing by promoting sound appraisal judgment❓.
  • Ensuring compliance with USPAP standards.

  II. Scientific Principles Underpinning Reconciliation

Reconciliation isn’t arbitrary; it’s rooted in several scientific and statistical principles that guide the appraiser’s judgment.

• A. Statistical Weighting: The most reliable approaches should have more importance.

  • Value indicators may not be equally reliable. Statistical weighting is a process where each indicator receives a weight based on its reliability and relevance.
  • This weighting is not explicitly numerical but is instead manifested through the depth of analysis and supporting evidence presented for each indicator.
  • The appraiser’s judgment is used as the determining factor for selecting which indicators to rely on and to what degree.
  • For example, a comparable sale requiring fewer adjustments and exhibiting greater similarity to the subject property warrants a higher weighting than a comparable requiring numerous adjustments.

• B. Principle of Substitution:

  • If there are more value indicators for the same property, a potential buyer would pay at most the price of another property offering the same utility.
  • This principle implies that indicators should converge towards a reasonable range.
  • Formula: V = min(V1, V2, … , Vn), where V is the final value opinion, and V1 to Vn are the value indicators.

• C. Data Reliability and Sample Size:

  • Statistical Significance: A value indicator’s reliability increases with the size and quality of the underlying dataset.
    • A larger sample size reduces the impact of outliers and provides a more stable estimate of the true population parameter (e.g., market value).
    • Equation: SE = s / √n, where SE is the standard error, s is the sample standard deviation, and n is the sample size. A smaller standard error indicates greater reliability.
  • Data Verification: Scrutinizing data ensures accuracy and reduces bias.
    • For instance, verifying comparable sales data directly with involved parties (buyers, sellers, brokers) strengthens the reliability of the sales comparison approach❓❓.

III. Key Factors Influencing Reliability and Relevance

The reliability and relevance of value indicators are paramount in the reconciliation process.

• A. Amount of Data:

  1. Statistical Sampling: Indicators derived from larger, statistically significant samples are generally more reliable.
  2. Detailed Data: Indicators built upon in-depth data analysis exhibit enhanced reliability.
  3. Independent Sources: Convergence of multiple independent sources bolsters confidence in the value indicator.

• B. Accuracy of Data and Techniques:

  1. Data Verification: Rigorous verification processes are essential for data accuracy.
     • Example: Confirming sale details (price, date, concessions) through official records or involved parties.
  2. Appropriate Techniques: Employing appraisal techniques aligned with the appraisal problem ensures accuracy.
     • Example: Using the sales comparison approach for residential properties in active markets.

• C. Relevance to the Appraisal Problem:

  1. Consistency with Assignment Terms: Indicators must align with the stated purpose and scope of the appraisal assignment.
     • Example: If appraising market value, indicators derived from forced sales would be less relevant.
  2. Appropriate Appraisal Techniques: The chosen appraisal method must be appropriate for the property type and market conditions.
     • Example: Income Capitalization is a better fit for investment properties, where income is a large factor in the value.

IV. Practical Applications and Examples

To solidify understanding, let’s examine practical applications of reconciliation:

• A. Case Study: Single-Family Residence Appraisal

  • Scenario: Appraising a detached single-family home with the sales comparison and cost approaches.

  • Value Indicators:

    • Sales Comparison: Adjusted range $450,000 - $470,000.
    • Cost Approach: Depreciated cost new $460,000.
      • Reconciliation:
        1. Reliability Assessment: Sales comparison relies on strong comparable data, whereas the cost approach is more subjective (depreciation estimates).
        2. Weighting: Greater weight to the sales comparison approach due to active market.
        3. Final Opinion: A final value opinion of $465,000 was selected, falling within the sales comparison range and close to the cost approach, demonstrating support for the conclusion.
        4. In URAR, the appraiser indicated and analyzed the Sales Comparison approach and the Cost approach.
        5. The appraiser indicated whether or not the subject was appraised as is, and listed the market value.

• B. Experiment: Impact of Data Quality on Reconciliation

  • Objective: Evaluate how varying data quality influences the final value opinion.
  • Setup: Two appraisal scenarios:
    1. High-Quality Data: Verifiable comparable sales, detailed property information.
    2. Low-Quality Data: Unverified sales, incomplete data, vague descriptions.
  • Procedure: Reconcile value indicators in each scenario and compare the confidence level in the final opinion.
  • Expected Result: Higher confidence and narrower value range with high-quality data; wider range and lower confidence with low-quality data.

V. Mathematical Formulas and Equations

While reconciliation is primarily judgmental, mathematical tools aid in analyzing value indicators.

• A. Weighted Average: If one wants to give a value to a particular comparable, it can be calculated as

  • V = (w1*V1 + w2*V2 + … + wn*Vn) / (w1 + w2 + … + wn)

    • Where: V is the reconciled value, Vi represents each value indicator, and wi represents the associated weight of each indicator
      *Example:
    • Comparable Sale 1 Market Value Indication $450,000 Weight 50%
    • Comparable Sale 2 Market Value Indication $460,000 Weight 30%
    • Comparable Sale 3 Market Value Indication $470,000 Weight 20%
    • (450,000*.5)+(460,000*.3)+(470,000*.2) = $457,000

• B. Range Analysis:

  • Value Range = Highest Indicator - Lowest Indicator

    • A smaller range suggests greater convergence and higher confidence in the final opinion.

VI. Supervisory Implications and Review Considerations

For Supervisory Appraisers, overseeing the reconciliation process is vital:

• A. Training Trainees:

  • Emphasize the importance of objectivity, thorough data analysis, and clear articulation of the reasoning behind weighting decisions.
  • Teach the scientific and statistical principles that underpin value indicator reliability.
  • Require detailed explanations in appraisal reports justifying the final value opinion.

• B. Reviewing Reconciliation Sections:

  • Scrutinize the Justification: Is the rationale behind weighting decisions clearly articulated and supported by evidence?
  • Examine Data Quality: Were appropriate data sources used and verified?
  • Ensure Consistency: Does the final opinion align with the analysis and reasoning presented throughout the report?

Practical Considerations As a supervisory appraiser, it is of utmost importance to ensure all appraisal reports are thoroughly reviewed in order to avoid the possibility of having an opening where your apprentice’s reasoning can be discredited. This review process should cover all of the concepts presented within this chapter. If the work does not pass muster in a critical review, do not send it out!

VII. Conclusion

Reconciliation is a complex but crucial element of the appraisal process, demanding sound judgment, thorough data analysis, and a grasp of underlying scientific principles. By mastering these concepts, both Supervisory and Trainee Appraisers contribute to defensible, credible value opinions that meet the highest professional standards, bolstering their standing in the appraisal industry.
