Optimal Valuation of Claims on Noisy Real Assets: Theory and an Application

A theory for valuing claims on noisy real assets is developed and applied. Central to the theory is determination of the dynamics for the best estimate of real asset value. The dynamics of the value estimate are shown to differ from the dynamics of the true asset value only in the arrival rate of information. The rate of information arrival in the value estimate can be faster or slower than information arrival in the true asset value, which can lead to unexpected outcomes in the valuation and exercise of options on noisy real assets. The theory we develop is illustrated through an application. An imperfectly competitive market for real estate development is examined, in which agents compete over the timing of lead investment. Information spillover and free–rider incentives are shown to cause significant delay in lead investment. Delay together with a competitive response once lead investment has occurred explain observed patterns of development in gentrified urban land markets and multistage development projects.     

Optimal Comparable Selection and Weighting in Real Property Valuation

This paper formalizes certain aspects of the sales comparison approach to valuation that heretofore have been quite ad hoc. Specifically, it applies statistical theory to decisions about how many comparables to select, what the criteria for comparable selection should be, and how the proper weights for each adjusted value estimate can be determined such that the final value estimate is both unbiased and of minimum variance. Several results are derived that run counter to conventional practice; for example, it may not always be optimal to consider first the "best" comparables because of a lack of independence among their adjusted value estimates. Furthermore, it is always desirable to consider more comparables (regardless of how "bad") so long as their adjusted value estimates are optimally weighted in the final value estimate. Finally, weights usually selected for "inferior" comparables are typically too small. A final exercise empirically applies the methodology to a sample of sales.     

Optimal Comparable Selection and Weighting in Real Property Valuation: An Extension

Vandell (1991) recently developed a rigorous minimum variance technique for selecting and weighting comparables in real estate appraisal. This article extends Vandell's methodology in three areas: (1) an alternative objective function; (2) an approach that explicitly recognizes the non-negativity constraint on comparable weights; and, (3) a more robust comparable inclusion process. Using Vandell's data, we show how our methodology modifies Vandell's results.     

Redevelopment of Real Assets

Real assets can be redeveloped repeatedly. Unlike financial assets, the option to redevelop real assets can be exercised infinitely often. For a depreciating real asset, the optimal exercise policy and resulting market values are calculated analytically and compared to the standard solution with at most one redevelopment. Relative to the standard solution, redevelopment is on average more frequent and less extensive, and the resulting market values are greater.     

The Substitutability of Real Estate Assets

This paper investigates the degree of substitutability between securitized real estate assets and real estate assets whose prices are appraisal-based. Given the insensitivity of unsecuritized asset's returns to the returns on stock market indices, equilibrium asset pricing models cannot be used to compare these two avenues of investment. Two assets are deemed substitutable if the information sets underlying unbiased, minimum error variance estimates of their pricing parameters are identical. The empirical evidence shows that the prices of the transactions-based assets—real estate investment trusts and the stock price index of the home building industry—follow a random walk while the prices of the appraisal-based assets—FRC/NCREIF indices—do not. The variance decompositions of the vector autoregressions also show that the level of economic activity helps predict the price indices of appraisal-based assets while the stock market index and the term structure of interest rates are better predictors of the prices of transactions-based assets     

Portfolio Considerations in the Valuation of Real Estate

When a real asset rises in price faster than inflation (as real estate did in the late 1970s) and rises significantly in price over an extended period (as real estate has done for the last decade and one-half), it concerns valuation and investment professionals who fear about it being over-valued. One of the reasons for such price performance may be an increase in demand due to the portfolio characteristics of the asset during the period of time in question. For real estate this means the proportion included in optimal portfolios should be significant and increasing as individual tax rates increase in an environment of increasing average tax rates.
This study uses six tax brackets (0%, 10%, 20%, 30%, 40%, 50%) and portfolios consisting of three traditional assets (NYSE common stocks, corporate bonds and small stocks) plus three types of real estate (residential, business and farmland) to demonstrate that this is what has transpired in the real estate markets. Optimal portfolio weights are derived for each asset for after-tax portfolios. Real estate in general and residential real estate especially increased as a proportion of the optimal after-tax portfolio as individual tax rates increased. Other studies are used to demonstrate an environment of increasing average tax rates.     

Capital Asset Pricing and Real Estate Valuation*

This paper examines the Capital Asset Pricing Model with respect to its implications for real estate investment analysis and appraisal. The derivation of the CAPM, and theoretical problems with it, are discussed, along with its empirical validation. The similarities and differences between real estate and securities markets are evaluated. Alternative models to the CAPM are presented, followed by the conclusions.     

Optimal Real Estate Portfolios

In recent years, increasing attention has been paid the problem of analyzing, evaluating and selecting real estate investments within the context of a portfolio. Most approaches simply attempt to adapt existing theory and models from the well-developed literature of securities investments. Most adaptations or extensions to real estate are not without serious problems, however, because of several fundamental difficulties relating to optimization technology inadequacies and a general lack of reliable and consistent market data.
This article deals with the major problems of utilizing some of the classic securities investment models for real estate. Further, a risk-return model is advanced which overcomes most of the fundamental problems outlined earlier in the article.     

Real Assets,Liquidation Value and Choice of Financing

We use real estate firms to examine how asset liquidation values influence a firm's financing choice, because the productivity and quality of each asset is observable and potential measures of an asset's liquidation value are easier to ascertain ex ante. We show that compared to firms that issue equity, firms that issue debt have higher asset quality. The effect of their expected asset liquidation value is significant, even after we control for other factors that influence financing decisions. For firms whose assets' quality is not easily observable, we find that firms' financing choices depend heavily on conditions in the overall real estate market.     

Real Estate Valuation Models: Lender and Equity Investor Criteria

The use of valuation models that focus on lender criteria has been growing in the appraisal field. In the rush to build lender criteria into real estate valuation models, equity investor criteria, expectations, and requirements occasionally have been ignored. The specific criteria considered in this paper are the loan-to-value ratio and the debt coverage ratio for lenders and the equity dividend rate for equity investors. Each of these three criteria may be a binding constraint on value.
Graphical analysis provides a framework within which major real estate valuation models (i.e., Ellwood, McLaughlin, Gettel, Lusht-Zerbst, and Steele) are compared. A new valuation model (i.e., the Cannaday-Colwell model) is developed which utilizes the equity dividend rate.
The three definitional models (i.e., McLaughlin, Gettel, and Steele) are found to be relevant only by mere coincidence. Each of these models simultaneously considers two of the three key criteria, completely eliminating the possibility of consideration of anything else; i.e., the models become tautological.
It is shown that the discounted cash flow based models (i.e., Ellwood, Lusht-Zerbst, and Cannaday-Colwell) each tell one-third of the story. One of these models will be relevant depending upon whether the binding constraint is the maximum loan-to-value ratio, the minimum debt coverage ratio, or the minimum equity dividend rate. The relevant model is the one that yields the lowest value estimate of the three.     

Commercial Real Estate Valuation, Development and Occupancy Under Leasing Uncertainty

A model of commercial property valuation is developed where individual property owners are price takers and tenants randomly arrive and depart. Spot lease and tenant reservation prices are stochastic and correlated and can divert from but eventually revert back to market equilibrium. Within this framework we examine built property values and vacancy rates for varying parameter sets representing differing markets and economic conditions. We also examine how potential and existing vacancies, spot lease prices and tenant reservation prices feed back into development decisions. We demonstrate how preleasing acts as a hedge to the developer against the risk of leasing uncertainty.

Real Estate Valuation Under Rent Control: The Case of Santa Monica

This is a study on the impact of rent control in the city of Santa Monica on rents and apartment house values. Findings include that rent control has significantly lowered rents for tenants, lowered the real values of apartment buildings and that the gross rent multipliers of buildings sold subsequent to the passage of rent control failed to decline. This last finding is a result of, according to the author, optimism on the part of buyers that the controls will be modified or eliminated in the future.     

The Optimal Duration of Real Estate Listing Contracts

The length of the real estate listing contract is examined as a means of providing an incentive for brokers to act in the best interest of home sellers. A limitation on the duration of the contract accomplishes this objective by imposing a cost (namely, the foregone commission) on brokers who fail to complete a sale before the contract expires. The seller's optimal contract duration balances the benefits of improved incentives against the expected cost of renegotiating a new contract in the event of a failure bv the broker.     

The Gains from Corporate Selloffs: The Case of Real Estate Assets

Recent financial economics literature has hypothesized that variations in market structure influence the distribution of gains from corporate restructuring between buyers and sellers. We test this hypothesis using data on restructuring involving real estate assets by isolating the effects depending on multiple versus single bidders, acquisition frequency and transaction type. While we find gains for both buyers and sellers, the buyers gain only when they make few purchases. Those firms pursuing an acquisition strategy show no gains around the specific acquisition announcements. Additionally, both buyers and sellers are more likely to have a positive reaction to the announcement when the transaction is property rather than a division or subsidiary.     

The Markets for Real Estate Assets and Space: A Conceptual Framework

In this study, we present a simple analytic framework that divides the real estate market into two markets: the market for real estate space and the market for real estate assets. After describing the size and character of flows and stocks in the U.S. real estate market, we use our framework to demonstrate the important connections between the space and asset markets. We illustrate how these real estate markets are affected by the nation's macroeconomy and financial markets, tracing out the impacts resulting from various exogenous shocks on rents, asset prices, construction and the stock of real estate.     

Demand Uncertainty,Development Timing and Leasehold Land Valuation: Empirical Testing of Real Options in Residential Real Estate Development

This article develops and tests a long‐dated American call option pricing model for valuing development land under leasehold. We analyze and test option values in ten detailed Hong Kong cases involving purchase, holding, converting and developing land. We also test for optimal exercise of long‐dated American calls using processes based on the optimal trigger ratio feature of the perpetual American call option model. Generally, the empirical results confirm presence of a positive and nontrivial option premium (mean +5.274%) in the cases, and that developers appear to delay exercise to the point predicted by the real options model.

An Approach to Industrial Real Estate Market Segmentation and Valuation Using the Arbitrage Pricing Paradigm

This paper investigates whether a segmented market exists for industrial real estate with respect to risk and return characteristics. Given the existence of industrial market segmentation, the next issue examined is whether a submarket perspective or an integrated real estate market orientation provides better rate of return estimates for individual industrial properties using an Arbitrage Pricing Theory (APT) framework. The results support the existence of regional markets for industrial real estate. A submarket orientation rather than an integrated perspective is also found more appropriate in predicting returns on industrial real estate.
