Site Valuation: Methods and Highest and Best Use

Introduction

Real property valuation necessitates a rigorous and objective determination of site value, irrespective of the presence or absence of improvements. This chapter addresses the methodologies employed in site valuation, emphasizing the central role of highest and best use analysis. Site valuation is not merely an academic exercise; it is a critical input in various valuation techniques, most notably the cost approach and certain income capitalization methods (e.g., the building residual technique). Furthermore, legal and regulatory frameworks governing property tax assessment and eminent domain often mandate a separate site valuation to ensure equitable and defensible outcomes.

The scientific importance of accurate site valuation stems from its direct impact on resource allocation, investment decisions, and public policy. Land, as a finite resource, demands efficient utilization. Misallocation of land, resulting from inaccurate valuation, can lead to suboptimal economic development, environmental degradation, and social inequities.  Therefore, a thorough understanding of site valuation principles and practices is essential for informed decision-making in real estate.

This chapter elucidates the following key concepts:

1.  **Highest and Best Use (HBU):**  A comprehensive definition of HBU, grounded in its four fundamental criteria: legal permissibility, physical possibility, economic feasibility, and maximal productivity. The chapter will explore the distinction between HBU as if vacant and HBU as improved, and the implications of these differing scenarios. It will further address the relevance of the Principle of Anticipation on HBU analysis and also describe the concepts of interim use and legal nonconforming use.

2.  **Methodologies of Site Valuation:** A detailed examination of the principal methodologies used in estimating site value, including:

    *   Sales Comparison Method: Analysis of comparable land sales, emphasizing the critical elements of comparison and adjustment processes.
    *   Allocation Method: Application of land-to-value ratios derived from comparable sales.
    *   Extraction Method:  Derivation of site value by subtracting depreciated improvement costs from overall property value.
    *   Development Method:  Discounted cash flow analysis of potential land development projects to estimate present land value.
    *   Land Residual Method: Capitalization of the income attributable to the land.
    *   Ground Rent Capitalization: Capitalization of ground lease payments to estimate land value.
    *   Depth Tables: Application of the 4-3-2-1 method.

    For each methodology, the chapter will outline the underlying principles, data requirements, strengths, and limitations.

3.  **Principle of Consistent Use, Excess Land and Plottage:**  An analysis of the concepts of Principle of Consistent Use, Excess Land and Plottage as it relates to site valuation.

The primary educational goals of this chapter are to equip participants with:

*   A robust theoretical understanding of site valuation principles.
*   Practical skills in applying various site valuation methodologies.
*   The ability to critically evaluate the strengths and weaknesses of different valuation approaches.
*   Proficiency in identifying and analyzing the factors that influence site value.
*   An awareness of the legal and regulatory context surrounding site valuation.

By mastering these objectives, participants will be well-prepared to conduct accurate and defensible site valuations in a variety of professional contexts.

Key improvements and explanations:

• Strong Opening: Immediately establishes the scientific importance of the topic and its practical applications.
• Precise Language: Replaced vague terms with more precise and academic vocabulary (e.g., “accurate” became “robust”).
• Explicit Goals: Clearly states the educational objectives of the chapter in terms of knowledge, skills, and awareness.
• Methodological Rigor: Emphasizes the importance of critical evaluation and the limitations of each method, reflecting a more scientific approach.
• Contextual Awareness: Acknowledges the legal and regulatory environment, adding a layer of complexity and relevance.

Chapter 6: Site Valuation: Methods and Highest and Best Use

I. Introduction: The Cornerstone of Land Valuation

Site valuation, the process of determining❓ the economic worth of a parcel of land, is a fundamental skill in land valuation. This chapter delves into the critical concepts and methods involved in site valuation, emphasizing the central role of highest and best use (HBU). Accurately assessing site value is essential for various appraisal techniques, including the cost approach and the building residual technique of income capitalization, as well as for legal requirements in property tax assessment and condemnation.

II. Highest and Best Use (HBU): The Guiding Principle

A. Defining Highest and Best Use

The highest and best use (HBU) of a property is defined as the reasonably probable and legal use of a vacant or improved property that is physically possible, appropriately supported, financially feasible, and results in the highest value. This concept is the bedrock upon which all valuation efforts are built.

B. The Four Tests of Highest and Best Use

To determine the HBU, the following four tests must be applied sequentially:

1. *Legally Permissible:* The proposed use must comply with all applicable zoning regulations, building codes, environmental laws, deed restrictions, and other legal limitations. Uses that violate legal constraints are immediately eliminated.

    *Example:* A parcel zoned for single-family residential use cannot have its HBU determined to be a commercial retail outlet, regardless of its profitability potential.

2. *Physically Possible:* The site's physical characteristics, such as size, shape, topography, soil conditions, access, and environmental factors, must be suitable for the proposed use.

    *Example:* A steeply sloped site might be physically unsuitable for constructing a large industrial facility, even if legally permitted.  Soil bearing capacity is a common physical limitation.

3. *Financially Feasible:* The proposed use must generate sufficient income or utility to justify the costs of development or continued operation. The anticipated revenues must exceed the expenses and provide an adequate return on investment.

    *Formula:*

       `Net Operating Income (NOI) - Expenses >= Required Return`

       where `NOI` is the revenue less operating expenses; `Expenses` include development costs, operating costs, etc.; and `Required Return` is the investor's minimum acceptable return on invested capital (land cost + improvement costs).

    *Example:* While a luxury hotel might be a legally permissible and physically possible use on a particular site, the demand for such a hotel in that location might be insufficient to generate enough revenue to cover operating costs and provide a reasonable profit, making it financially infeasible.

4. *Maximally Productive:* Among all the legally permissible, physically possible, and financially feasible uses, the HBU is the one that maximizes the property's value. This use generates the greatest net return or benefit to the owner.

    *Example:* Two uses, a low-rise apartment building and a high-rise condominium, are both legally permissible, physically possible, and financially feasible.  The use that yields the higher net present value (NPV) of future income streams is the maximally productive, and therefore the HBU.

C. HBU: As Vacant vs. As Improved

A key distinction is made between the HBU of the land “as if vacant” and the HBU of the property “as improved.”

1. *HBU as Vacant:* This analysis considers the optimal use of the land assuming it is devoid of any existing structures. It disregards the current improvements and focuses solely on the land's potential.

2. *HBU as Improved:* This analysis considers the optimal use of the property in its current state, taking into account the existing improvements. This analysis accounts for the cost of demolition, renovation or change of use.

    *Example:* A site currently improved with a small retail store might have an HBU as vacant of a high-rise office building.  However, the cost of demolishing the existing store and constructing the office building might be so high that the HBU as improved is to continue operating the retail store for the remainder of its economic life.

D. Interim Use and Legal Nonconforming Use

1. *Interim Use:* Is a short-term or temporary use of a property that is likely to be replaced by a more productive use in the near future.

2. *Legal Nonconforming Use:* Is a use of a property that was legal when it was established but no longer conforms to current zoning regulations.

III. Site Valuation Methods

Several methods are employed to estimate site value. The choice of method depends on data availability, property characteristics, and the specific appraisal assignment.

A. Sales Comparison Approach

This is the most widely used and generally considered the most reliable method. It involves comparing the subject site to similar vacant sites that have recently sold, with appropriate adjustments❓ made for differences in characteristics.

1. *Data Sources:*
    *   Multiple Listing Services (MLS)
    *   Real estate brokers and agents
    *   County recorder's offices
    *   Title companies
    *   Commercial data providers (e.g., CoreLogic®, FNC, Inc.)
2. *Elements of Comparison:*  Adjustments are made to comparable sales prices to account for differences between the comparable properties and the subject property.  Common elements include:
    *   *Property Rights Conveyed:* Fee simple, leasehold, etc.
    *   *Financing Terms:* Cash equivalent analysis.
    *   *Conditions of Sale:* Arm's length transactions.
    *   *Market Conditions:* Changes in market values over time.
        *Formula:*

           `Adjusted Sale Price = Sale Price +/- Adjustments`
    *   *Location:* Neighborhood characteristics, access, amenities.
    *   *Physical Characteristics:* Size, shape, topography, soil conditions, frontage, etc.
    *   *Economic Characteristics:* Zoning, development potential, utility availability.

    *Example:* Comparable Site A sold for $100,000 but is located in a less desirable neighborhood than the subject site. If the appraiser estimates the difference in location value at $10,000, a +$10,000 adjustment would be applied to the comparable's sales price, resulting in an adjusted sale price of $110,000 for Comparable A.

B. Allocation Method

This method estimates site value based on a typical ratio of land value to total property value in the market.

*   *Formula:*

    `Site Value = Total Property Value x Allocation Ratio`

    where `Allocation Ratio` is the typical ratio of land value to total property value for similar properties.

*   *Example:* If typical properties in the area have a land value that represents 20% of the total property value, and a comparable improved property sold for $500,000, the allocated land value would be $100,000.
*Used: Property tax valuation and support other valuation methods.*
*Strengths: Is a quick method of estimating the land value.*
*Weaknesses: This method should be relied on for small-value adjustments.*

C. Extraction Method

This method is used to determine a subject’s value based on what an improved sales comparable property’s costs were and subtrating these amounts to derive the value of the subject land

*   *Formula:*
    `Site Value = Improved Property Value - Depreciated cost of improvements`
    `Depreciated cost of improvements = Cost new of improvements - Accumulated depreciation`
*Used: When it is hard to find enough vacant sales to properly support an opinion of value.*
*Strengths: Can be more accurate than the allocation method.*
*Weaknesses: Improvement must be reasonably new.*

D. Development Method (Subdivision Analysis)

This method estimates the value of land by projecting the revenues and expenses associated with developing and selling subdivided lots.

*   *Steps:*
    1.  Estimate the gross sales price of the completed lots.
    2.  Deduct all development costs (construction, infrastructure, marketing, sales, financing, etc.).
    3.  Discount the resulting net cash flow back to present value using an appropriate discount rate to reflect the time value of money and risk.
*   *Formula:*

    `Site Value = Present Value of (Projected Revenue - Development Costs)`
    `Present Value= CF1/(1+r)^1 + CF2/(1+r)^2 ... CFn/(1+r)^n`
     where `CF` is each cashflow stream
     and `r` is the discount rate.
    *Weaknesses: This method may require a lot of steps, and thus be complex.*

E. Land Residual Method

This is an income capitalization technique that isolates the income attributable to the land and then capitalizes that income to estimate its value.

*   *Steps:*
    1.  Estimate the net operating income (NOI) of the improved property.
    2.  Determine the value of the improvements.
    3.  Estimate the income attributable to the improvements by multiplying the improvement value by an appropriate capitalization rate for buildings.
    4.  Subtract the income attributable to the improvements from the total NOI to determine the income attributable to the land (land residual income).
    5.  Capitalize the land residual income using a land capitalization rate to estimate land value.
*   *Formulas:*
    *   `Income (I) = Rate (R) x Value (V)`
    *   `Property Value = Land Value + Improvement Value`

    *Example:*
      Total Annual Net Income: 200,000
      Capitalization Rate for property: .08
      Indicated value of entire property: $2,500,000
      Market Cap rate (improvements): 12%
      Improvements (calculated depreciated value): $650,000

      Then the calculation to find value of land is:
        Improvements - Value of Building Improvements/ Market
        Cap Rate : $2,500,000 *12% = $78,000
        Capitalization of Land income 200,000-78,000 = $122,000
        Divided by the capitalization Rate 8% ($122,000 / 0.08) = $1,525,000

F. Ground Rent Capitalization

This method capitalizes the ground rent paid on a leasehold property to estimate land value. The ground rent is the periodic payment made by the tenant for the right to use the land.

*   *Formula:*

    `Site Value = Ground Rent / Capitalization Rate`

    where `Capitalization Rate` is the appropriate capitalization rate for land in the market.

    *Example:* A property generates $10,000 per year in ground rent. Similar land parcels have a market capitalization rate of 10%. So
    Indicated land Value = 10,000 / 0.10 = 100,000

G. Depth Tables

Provides a way to value an under-sized lot. It is known as the “4-3-2-1” Method.
A land parcel can be seen as worth as follows:
1st ¼ = 40% of Value
2nd ¼ = 30% of Value
3rd ¼ = 20% of Value
4th ¼ = 10% of Value
Weaknesses: There is no empirical evidence supporting this process.*

IV. Reconciliation and Final Value Estimate

After applying one or more of the site valuation methods, the appraiser reconciles the results to arrive at a final estimate of site value. Reconciliation involves analyzing the strengths and weaknesses of each method and giving the most weight to the method that is most reliable and applicable to the specific appraisal problem.

V. Conclusion

Accurate site valuation is a critical component of the overall appraisal process. By understanding the principles of HBU and mastering the various site valuation methods, appraisers can develop well-supported and credible opinions of value.

VI. Practical Exercises and Experiments

1. Case Study: Present students with a detailed property description and require them to perform an HBU analysis.
2. Market Data Analysis: Students gather and analyze comparable sales data for vacant land and apply the sales comparison approach.
3. Development Scenario: Students create a hypothetical subdivision development plan and estimate site value using the development method.
4. Analysis: Students find a property value on the internet (Zillow, Trulia) and assess for accuracy. What would make for a more accurate comparable sale value than the algorithm of Zillow?
