Chapter 18: Risk Analysis
2
Introduction to Risk Analysis Risk is the probability that events will not occur as expected. Actual return may differ from the expected return. Risk is important for several reasons: Investor’s expected return depends on risk. Risk must be considered when selecting comparable sales. Discount rates must reflect level of risk.
3
Types of Risk Space Market Risk Risk due to changes in the market for real estate space. Can result from changes in the supply or demand for space. Capital Market Risk Risk that changes in the market for capital will affect value. Caused by changes in mortgage interest rates or equity yield rates. Affects investors even if they do not use debt financing.
4
Types of Risk Financial Risk Results from the use of debt financing (leverage). Leverage can increase expected return. Leverage always increases financial risk. Liquidity Risk The difficulty of converting an investment into cash at a price close to market value within a reasonable time. Real estate has a relatively high degree of liquidity risk: Not publicly traded Relatively few buyers for a particular property at a given point in time
5
Types of Risk Inflation Risk Risk that unexpected inflation will cause future income from operations and reversion to lose purchasing power. Historically real estate has not had much inflation risk. Inflation tends to increase replacement cost Market rents can increase with inflation Lease provisions like CPI adjustments and expense pass-throughs help protect owner against unexpected inflation Real estate may have more inflation risk in a weak market
6
Types of Risk Environmental Risk Risk that environmental factors will affect ability to develop or lease space, e.g., asbestos or toxic waste Often difficult to measure and the cost to cure the problem can exceed the value of the property. Legislative Risk Risk do to changes in laws and regulations Examples Federal income tax laws Environmental regulations Changes in zoning Changes in land-use regulations Building codes
7
Types of Risk Management Risk Risk resulting from poor management. Properties requiring specialized management such as convention hotels and regional malls have greater management risk.
8
Sensitivity Analysis Measures how changes in one of the assumptions affects the performance of the property. Scenarios are alternative assumptions about how the property might perform. Considers interactions between assumptions. Pessimistic, most likely and optimistic scenarios are typically considered.
9
Expected Return Returns may be for calculated for different scenarios The expected return is found by weighing each return by its probability of occurrence
10
Expected Return ScenarioOverall YieldProbability Pessimistic50.3 Most likely100.4 Optimistic200.3 Expected Return = 0.05(0.30) + 0.10(0.40) + 0.20(0.30) = 0.1150 or 11.50%
11
Variance and Standard Deviation Variance is a measure of the uncertainty or risk associated with an investment. Measures the tendency of individual returns to vary from the expected return. The standard deviation is the square root of the variance.
12
Variance
13
Variance and Standard Deviation Variance = 0.30(.05-.1150) 2 +0.40(0.10-0.1150) 2 +0.30(0.20-0.1150) 2 Variance=0.003525 or 0.3535% Standard deviation is equal to the square root of the variance. Standard deviation = (0.003525) 1/2 = 0.05937 or 5.937%
14
Ranking Investments The expected return and standard deviation can be used to compare investment alternatives. An investment with a higher expected return is not better if it also has greater variance.
15
Ranking Investments Expected ReturnStandard Deviation Property A9%4% Property B9%2% Property C10%4%
16
Ranking Investments Sharpe Ratio = (Portfolio return – Risk-free rate)/Portfolio standard deviation Property A = 9%/4% = 2.25 Property B = 9%/2% = 4.50 Property C = 10%/4% = 2.50
17
Expected Present Value Present values can be calculated for different scenarios. The expected present value is found by weighing each present value by its probability of occurrence. This helps convey the degree of uncertainty in the value estimates.

Expected Present Value Example 1.Using a discount rate of 10%, find the PV of the property under each scenario. ScenarioYear 1Year 2Year 3Year 4Year 5Resale Pessimistic$100,000 $1,000,000 Most Likely$100,000$102,000$104,040$106,121$108,243$1,200,000 Optimistic$100,000$104,000$108,160$112,486$116,986$1,400,000 Pessimistic PV@10% = $1,000,000 Most Likely PV@10% = $1,138,171 Optimistic PV@10% = $1,276,880
20
Expected Present Value Example 2.What is the expected present value? Expected PV = 0.20($1,000,000) + 0.50($1,138,171) + 0.30($1,276,880) Expected PV = $1,152,150
21
Expected Present Value Example 3.Compute the Variance and Standard Deviation. Variance = 0.20(1,000,000-1,152,150) 2 + 0.50(1,138,171- 1,152,150) 2 + 0.30(1,276,880-1,152,150) 2 Variance = $9,394,902,591 Standard Deviation = ($9,394,902,591) 1/2 Standard Deviation = $96,927
22
Expected Present Value Example 4.What range of value estimates can you predict within 2 standard deviations of the mean? $1,152,150 + (2 x $96,927) = $1,346,004 $1,152,150 – (2 x $96,927) = $958,296
23
Partitioning the IRR A method of calculating the relative contribution of different components of cash flow Cash flow can be broken down as follows: 1.NOI Income from existing leases Income from expected lease renewals 2.Reversion Cash flow from recapture of original investment (i.e. purchase price) Cash flow from expected price appreciation
24
Partitioning the IRR Partitioning uses the IRR as a discount rate The present value of each component of the cash flow stream is calculated The total of these present values must equal the purchase price A project with a greater proportion of its return from reversion is usually considered more risky.
25
Example of Partitioning the IRR An investor considers purchasing one of the following properties. Each can be purchased for $500,000 and would have NOI and expected sales price after 5 years as follows. Property Purchase PriceNOISales Price A$500,000$50,000$500,000 B $10,000$744,204 Calculate the IRR and partition the IRR for each property.

27
Discounting the NOI and Reversion at Different Rates NOI is often considered less risky than cash flow from reversion Thus, the reversion can be discounted at a higher rate than the NOI
28
Discounting the NOI and Reversion at Different Rates A property is leased for 5 years with a net lease at $90,000 per year. It is expected to sell for $1,200,000 in 5 years when the lease expires. The discount rate for the leased portion of the cash flow is 9%, and the discount rate for the reversion is 12%. What is the indicated value? PV of $90,000 for 5 years @ 9% = $350,069 PV of $1,200,000 at the end of 5 years @ 12% = $680,912 Indicated value = $350,069 + $680,912 = $1,030,981
29
Discounting the NOI and Reversion at Different Rates Assuming the property is purchased for $1,030,981, what is the IRR? CF0=-1,030,981 C01=90,000, F01=4 C02=90,000+1,200,000=1,290,000, F02=1 IRR=11.34%
30
Effect of Leverage on Financial Risk As the loan to value ratio increases the lenders equity yield will increase if leverage is positive. As the loan to value ratio increases the standard deviation (risk) also increases.
31
Effect of Leverage on Financial Risk Consider a property with a purchase price of $100,000 with debt financing at a rate of 10% over 30 years. Scenario NOI per yearResaleProbability Pessimistic$10,000$90,0000.3 Most Likely$12,000$100,0000.6 Optimistic$14,000$110,0000.1
