Reconciliation and Final Value Opinion
Reconciliation and final value opinionโโ
I. The Scientific Foundation of Reconciliation
Reconciliation, in the context of real estate income estimation, represents the critical process of synthesizing multiple value indicators into a single, supportable final value opinion. This process goes beyond simple averaging, requiring the appraiser to apply sound judgment, experience, and a deep understanding of valuation principles. It is rooted in statistical concepts and decision theory.
A. Statistical Considerations
-
Central Tendency: While averaging is not the reconciliation method, an understanding of measures of central tendency is relevant. The mean (average), median (middle value), and mode (most frequent value) can provide a statistical overview of the value indicators. However, reconciliation requires weighting these indicators based on their reliability and relevance, a concept related to weighted averages.
- Formula: Mean = ฮฃx / n, where ฮฃx is the sum of all values and n is the number of values.
-
Variance and standard deviationโโ: Understanding the spread or dispersion of value indicators is crucial. A high variance or standard deviation suggests less consistency among the indicators, potentially indicating issues with data quality or market volatility.
-
Formula: Variance = ฮฃ(xแตข - ฮผ)ยฒ / (n-1), where xแตข is each value, ฮผ is the mean, and n is the number of values. Standard Deviation (ฯ) = โVariance.
- Sample Size: The reliability of a value indicator is statistically related to the sample size on which it is based. Larger, more representative samples generally lead to more reliable estimates.
B. Decision Theory
-
Expected Value: Reconciliation can be viewed through the lens of decision theory, where the appraiser seeks to maximize the expected value of their final value opinion. This involves assigning probabilities to each value indicator based on its reliability and relevance and selecting the value that optimizes expected accuracy.
- Formula: Expected Value = ฮฃ (Pแตข * Vแตข), where Pแตข is the probability of value indicator i being accurate and Vแตข is the value indicated by indicator i.
- Risk Assessment: The appraiser must consider the risk associated with each value indicator. Factors such as data verification, market volatility, and the subjectivity of adjustments contribute to the overall risk profile.
II. Reconciliation Process: A Detailed Examination
A. Review and Verification
- Data Accuracy: All data points, including comparable sales data, cost estimates, and income projections, must be rigorously checked for accuracy. Errors in calculations or data entry can significantly skew the final value opinion.
- Consistency: Ensure that all appraisal techniques are applied consistently to the subject property and all comparables. Inconsistent application of adjustments or capitalization rates can lead to unreliable value indicators.
- Assignment Compliance: Verify that all value indicators are derived in accordance with the terms of the appraisal assignment, including the definition of value, the intended use of the appraisal, and any specific requirements or limitations.
- Calculations: Re-examine all calculations for errors.
B. Assessing the Reliability of Value Indicators
- Data Quantity: Value indicators based on a larger statistical sampling of data, derived from more detailed data, or supported by several independent sources are generally considered more reliable.
- Data Accuracy: The accuracy of a value indicator depends on the accuracy of the supporting data and the accuracy of the technique used to derive the indicator from the data. This includes how well data has been verified.
- Relevance to the Appraisal Problem: The relevance of the value indicator to the particular appraisal problem influences the appraiserโs judgment. The indicator itself must be consistent with the terms of the appraisal assignment, and the appraisal technique used to derive the indicator must be appropriate.
- Weighting Value Indicators:
- Sales Comparison Approach: This approach may be given more weight if there are numerous, recent, and highly comparable sales. The reliability also depends on the verification and lack of extraordinary terms associated with those transactions.
- Cost Approach: The Cost Approach would hold greater weight for new or specialized properties.
- Income Approach: The Income Approach would hold greater weight for income-producing properties where reliable income and expense data are available.
C. The Role of Judgment
- Experience: Reconciliation inherently depends on the appraiser’s judgment and experience in analyzing market data and selecting the most appropriate value.
- Mathematical formulas or techniques (such as averaging) are not used in reconciliation.
- Evidence Support: The choice of a reconciled value should be supported by the evidence in the appraisal.
III. Practical Applications and Related Experiments
A. Example Scenario
- Property Type: A small office building.
- Appraisal Approaches: Sales Comparison, Cost, and Income.
-
Value Indicators:
- Sales Comparison: \$850,000
- Cost: \$900,000
- Income: \$875,000
The Sales Comparison Approach relied on verified sales of similar office buildings with adjustments for size, location, and occupancy rates. The Cost Approach estimated the replacement cost of the building less depreciation. The Income Approach capitalized the net operating income.
4. Reconciliation: After careful review, the appraiser concluded that the Income Approach provided the most reliable indicator, based on the stability of the tenant base and the availability of verifiable income and expense data. The Sales Comparison Approach was considered less reliable due to the limited number of truly comparable sales. The Cost Approach, while useful, was subject to greater uncertainty in estimating depreciation.
5. Final Value Opinion: The appraiser reconciled the value indicators by placing the most weight on the Income Approach, \$875,000.
B. Simulated Experiments
- Sensitivity Analysis:
- Experiment: Conduct a sensitivity analysis by systematically varying the key assumptions in each appraisal approach (e.g., discount rate, depreciation rate, sales adjustment factors).
- Observation: Determine how these variations affect the value indicators. This helps identify the most sensitive variables and assess the potential range of values.
- Reporting: This process is crucial in determining the most appropriate value based on the three approaches to value.
- “Blind” Reconciliation:
- Experiment: Have multiple appraisers independently reconcile the same set of value indicators.
- Observation: Compare the resulting final value opinions and identify areas of consensus and disagreement. This can highlight potential biases or inconsistencies in the reconciliation process.
IV. Final Value Opinion: Point Estimate vs. Range Value
A. Point Estimate
- Definition: The most common way to express a final value opinion is as a single dollar amount, known as a point estimate. This represents the appraiser’s best judgment of the property’s market value as of the effective date of the appraisal.
- Rounding: Final value opinions should be rounded to reflect the inherent uncertainty in the valuation process. Overly precise values (e.g., \$500,000.17) are unrealistic and lack credibility.
B. Range Value
-
Definition: As an alternative, an appraiser may provide a range value, which is an opinion of the range in which the property’s value is most likely to fall.
While the practice of providing a range in value is rare, an appraiser may provide a range in values where the market or property itself, is very unpredictable.
2. Application: For example, an appraiser may indicate a value range between \$475,000 and \$525,000.
V. Completing the URAR Reconciliation Section
- Indicate if the appraisal was made as is or is subject to the property being altered.
- List any conditioning factors.
- List any appraisal approaches used.
- Reaffirm the purpose of the appraisal.
- Set forth the opinion of market value and the appraiser signs and dates the appraisal report, and includes his or her appraisal license or certification number.
- Review to Insure Readability: An appraiser should review his or her work to insure that it is easily understandable to a non-appraiser reader.
Chapter Summary
Summary of “Reconciliation and final value opinionโ“
This chapter of the “Mastering Real Estate incomeโ Estimation” training course focuses on the crucial reconciliation process, which leads to the appraiser’s final value opinion. The chapter emphasizes that reconciliation is not a mathematical averaging of value indicators but a reasoned judgment based on the appraiser’s experience and a thorough review of all data, calculations, and reasoning used in the valuation process.
Main Scientific Points:
-
Reconciliation Defined: Reconciliation is the process of analyzing multiple value indicators (derived from different comparables, units of comparison, or appraisal techniques) to arrive at a single, supportable value opinion. It’s also the step in the appraisal process where the appraiser arrives at a final value opinion.
-
Subjectivity and Judgment: Mathematical averaging is explicitly rejected. The final value opinion relies heavily on the appraiser’s judgment and experience. This judgment must be supported by the evidence within the appraisal.
-
Review and Verification: The reconciliation process starts with a meticulous review of all data, calculations, and reasoning. This includes:
- Checking all calculations for accuracy and correcting errors.
- Ensuring consistent application of appraisal techniques across the subject property and comparables.
- Assessing the reliability of each value indicator.
- Ensuring all pertinent data is included and analyzed.
- Confirming value indicators alignโ with the assignment terms.
-
Reliability of Value Indicators: The reliability of a value indicator depends on:
- Amount of Data: Indicators based on larger, more detailed statisticalโ samples from multiple independent sources are considered more reliable.
- Accuracy of Data and Techniques: Data accuracy relies on verification, while the accuracy of the appraisal technique depends on its relevance to the appraisal problem.
- Relevance to the Appraisal Problem: The value indicator must align with the assignment terms, and the appraisal technique used must be appropriate for the property and situation.
-
Final Value Opinion: The appraiser must choose a reconciled value supported by evidence. This opinion is usually expressed as a “Point Estimate” (a single dollar amount), but a “Range Value” (a value range) is an alternative. Value opinions should be rounded for clarity.
-
URAR Completion: The appraiser completes the Reconciliation section of the Uniform Residential Appraisal Report (URAR). This includes indicating if the appraisal is “as is” or subject to alterations, listing conditioning factors, noting appraisal approaches used, reaffirming the appraisal purpose, and stating the market value opinion, followed by the appraiser’s signature, date, and license/certification number.
-
Clarity and Understandability: The appraiser’s work should be reviewed to ensure it is understandable to a non-appraiser reader.
Conclusions and Implications:
- Reconciliation is a critical step in the appraisal process that demands both analytical rigor and informed judgment. It is essential for developing a credible and defensible value opinion.
- Appraisers must meticulously document their reconciliation process, clearly explaining how they weighed different value indicators and why they arrived at their final opinion. This documentation is crucial for supporting the appraisal in a critical review.
- The emphasis on relevance highlights the importance of selecting appraisal techniques and data that are appropriate for the specific property and market conditions.
- The chapter implies that a failure to properly reconcile value indicators can lead to inaccurate appraisals and potentially adverse consequences for lenders, buyers, and other stakeholders.
