Capitalization & Discounting: Rate Selection and Applications

Chapter: Capitalization & Discounting: Rate Selection and Applications

Introduction

This chapter delves into the scientific principles underlying capitalization and discounting techniques, essential tools in real estate valuation. We will explore the theoretical underpinnings of rate selection, examine various models, and provide practical applications with mathematical formulations. This comprehensive analysis aims to equip you with a robust understanding of these crucial concepts for accurate property valuation.

1. Understanding Capitalization and Discounting

Capitalization and discounting are fundamental valuation techniques that convert future income streams into present value❓. Both methods rely on a rate (capitalization rate or discount rate) to translate expected future benefits into a current value estimate. The choice of the appropriate rate and model is critical to the accuracy of the valuation.

• Capitalization: Converts a single year’s stabilized income into value.
• Discounting: Converts a series of future cash flows into present value.

2. Rate Selection: Theoretical Framework

The selection of an appropriate capitalization or discount rate is paramount. The rate must reflect the risk inherent in the investment and the opportunity cost of capital.

• Risk-Free Rate: The theoretical rate of return on an investment with zero risk. Examples include government bonds.
• risk premium❓: An additional return required by investors to compensate for the risk associated with a specific investment.
• Opportunity Cost: The return an investor could earn on an alternative investment with similar risk.

The general formula for determining the required rate of return (k) can be expressed as:

k = r_f + RP

Where:

• k = Required rate of return
• r_f = Risk-free rate
• RP = Risk premium

Several methods exist for determining the risk premium:

1. Market Extraction: Analyzing comparable sales to extract the implied rate of return.
2. Survey Data: Utilizing surveys of investors to gauge their required rates of return for specific property types.
3. Build-Up Method: Summing individual risk components.

3. Capitalization Rate (Cap Rate) Derivation

The capitalization rate (R) is the ratio of net operating income (NOI) to property value (V):

R = NOI / V

Rearranging the formula, we can derive the value:

V = NOI / R

Several methods are used to derive capitalization rates:

1. Market Extraction: Analyzing comparable sales to extract the implied capitalization rate.

   • Example: A comparable property sold for $1,000,000 with a stabilized NOI of $80,000. The implied capitalization rate is $80,000 / $1,000,000 = 8%.
     2. Band of Investment: Weighting the required rates of return for different sources of capital (debt and equity).

   • Formula: R = (L/V * m) + (E/V * Y_e)

     Where:

     • R = Overall capitalization rate
     • L/V = Loan-to-value ratio
     • m = mortgage constant❓ (annual debt service / loan amount)
     • E/V = Equity-to-value ratio
     • Y_e = Required equity yield rate

     Example:
     Assume L/V = 70%, m = 0.08, E/V = 30%, Y_e = 0.12

     Then, R = (0.7 * 0.08) + (0.3 * 0.12) = 0.056 + 0.036 = 0.092 or 9.2%
     3. Gordon Growth Model: A simplified approach that relates the cap rate to the discount rate and expected income growth.

   • Formula: R = Y - g

     Where:

     • Y = Discount rate
     • g = Expected income growth rate

     Example: If discount rate (Y) is 10% and growth rate (g) is 2%, then capitalization rate (R) = 10% - 2% = 8%
     * Experiment: Conduct a sensitivity analysis by varying the growth rate (g) to observe its impact on the capitalization rate (R). For instance, increase ‘g’ to 3% and 4% and note the corresponding decrease in ‘R’. This highlights the inverse relationship between growth and cap rates.

4. Discount Rate Derivation

The discount rate is used in discounted cash flow (DCF) analysis to convert future cash flows into their present value. The discount rate represents the required rate of return that an investor expects to receive for undertaking the investment, considering its risk profile and opportunity cost.

The derivation of discount rate mirrors that of the cap rate’s, including market extraction, band of investment, and build-up methods.

5. Capitalization Techniques: Traditional Models

Various capitalization techniques exist, each with its own assumptions and applicability.

1. Direct Capitalization: Applies a single capitalization rate to a stabilized NOI to estimate value.

   • Formula: V = NOI / R
     2. Yield Capitalization: Utilizes a discount rate to convert a stream of future income into present value. Includes variations for different income patterns.
     3. Straight-Line Capitalization: Assumes a linear decline in income and value. The capitalization rate is a combination of the yield rate and the straight-line rate of change.

   • Formula: R = Y - Aa

     Where:

     • R = Capitalization rate
     • Y = Yield rate
     • A = Relative change in value in n periods
     • a = 1/n
       • Example: If the income stream is expected to decline and the value is expected to fall 25% in 10 years and the yield rate is 12%, then the formula becomes

     R = 0.12 - (-0.25 * 0.1) = 0.145

     Value = Income / R = 19,000 / 0.145 = $131,034

     The reciprocal of the recapture rate is the economic life.
     4. Exponential-Curve (Constant-Ratio) Changes: Assumes income and value change at a constant ratio.

   • Formula: R = Y - CR

     Where:

     • R = Capitalization rate
     • Y = Yield rate per period
     • CR = Rate of change per period

     If income and value expected to change at the same rate, the capitalization rate is expected to remain constant. The formula R=Y-CR where Y is the yield rate per period and CR is the rate of change per period.
     * Example: An income-producing property is expected to produce net operating income of $50,000 for the first year. Thereafter both net operating income and value are expected to grow at a constant ratio of 2% per year. To appraise the property to yield 11%, the formula is R =Y - CR = 0.11 - 0.02 = 0.09
     Value = $50,000 / 0.09 = $555,556

     The elements in the above equation can be transposed so that: Y = R + CR

6. Discounted Cash Flow (DCF) Analysis

DCF analysis is a versatile valuation technique that projects future cash flows and discounts them back to present value using a discount rate.

1. Process:

   a. Project future cash flows (NOI, capital expenditures, reversion value).
   b. Select an appropriate discount rate.
   c. Discount each cash flow to its present value using the following formula:

   ```
   PV = CF / (1 + r)^n
   ```
   
   Where:
   
   *   PV = Present value
   *   CF = Cash flow
   *   r = Discount rate
   *   n = Number of periods
   

   d. Sum the present values of all cash flows to arrive at the property’s value.
   2. Terminal Value (Reversion): Represents the value of the property at the end of the projection period. Often calculated using a terminal capitalization rate.
   3. Applications:

   a. Valuing properties with irregular income streams.
   b. Analyzing investment opportunities.
   c. Extracting yield or discount rate from comparable sales.
   4. Level-Equivalent Income: Any pattern of income can be converted into a level-equivalent income.

   • Formula: R = Y - Aa can be used to solve for the value of any pattern of income once that income has been converted into its level equivalent.

     To calculate the level-equivalent income, first calculate the present value of the cash flows at the yield rate.

     Example: An appraiser is valuing a property with net operating income of $200,000, growing❓ at 4% per year. If the value is expected to increase 15% over a five-year projection period (A, = 15%) and the appropriate yield rate is 12%, the value can be calculated by first calculating the level-equivalent income and then dividing that income by an overall capitalization rate developed us- ing the level income property model.
     5. Investment Analysis: Used to test the performance of real estate investments at a desired rate of return.
     Measures of investment performance include:
     Net present value
     Internal rate of return
     Payback period
     Profitability index (or benefit/cost ratio)
     Time-weighted rate

7. Practical Applications and Experiments

1. Sensitivity Analysis: Conduct sensitivity analyses on key assumptions (e.g., discount rate, growth rate, occupancy) to assess their impact on the valuation.
2. Scenario Planning: Develop multiple scenarios (e.g., optimistic, pessimistic, most likely) to capture the range of possible outcomes.
3. Comparative Analysis: Compare the results of different valuation methods (direct capitalization, DCF) to ensure consistency and reasonableness.
4. Experiment: Apply varying discount rates❓ (e.g., 8%, 10%, 12%) to the same set of projected cash flows and calculate the resulting present values. Document and analyze the effect of discount rate variations on the final value estimation. This demonstrates the sensitivity of DCF analysis to the discount rate.

8. Forecasting

Forecast categories addressed in DCF analysis include:

• Current market rental rates, lease expiration dates, and expected rental rate changes
• Lease concessions and their effect on market rent
• Existing base rents and contractual base rent adjustments
• Lease extensions and renewal options
• Existing and anticipated expense recovery (escalation) provisions
• Tenant turnover
• Vacancy loss and collection allowance
• Operating expenses and changes over the projection period
• Net operating income
• Capital items including leasing commissions and tenant improvement allowances
• Reversion and any selling or transaction costs
• A discount or yield rate (or rates)
