Embedded Options in the Mortgage Contract

Loss mitigation is the process by which lenders attempt to minimize losses associated with foreclosure. As competition increases in the mortgage industry, lenders and servicers are under great pressure to adopt loss mitigation tactics rather than simply use foreclosure as the means of dealing with borrowers in default. This study presents a mortgage-pricing model that fully specifies all borrower options with respect to default, including the ability to reinstate the mortgage out of default. We document the impact of various loss mitigation programs, including forbearance and antideficiency judgments, as well as the value of credit on borrower default behavior.     

The Adjustable Balance Mortgage: Reducing the Value of the Put

We propose a new mortgage contract that endogenously captures the risk of house price declines to minimize default risk resulting from changes in the underlying asset value while still retaining contract rates near the cost of a standard fixed‐rate mortgage. By reducing the role of the legal system in mitigating house price risk, the new mortgage reduces the negative externalities and social costs arising from defaults. In other words, the new mortgage minimizes the need to use the legal foreclosure system to deal with the economic risk of house price declines.     

A New Spin on the Jumbo/Conforming Loan Rate Differential

This article uses house-price transaction data to estimate volatility in house prices. The volatility parameter is an input into a mortgage-pricing model that is used to simulate the contract interest rate that balances the mortgage contract. By segmenting the house-price transaction into high- and low-valued homes, we are able to estimate a theoretical jumbo/conforming loan rate differential. Simulation results demonstrate that the differences in volatility between high- and low-priced homes can produce a contract loan rate differential, holding all else constant. The article also presents a discussion of the problems inherent to estimating volatilities form assets with infrequent trades and long holding periods.     

A Contingent Claims Analysis of Real Estate Listing Agreements

This article examines real estate brokerage contracts as contingent claims. It derives terminal and boundary conditions for this contract. A Nelson and Ramaswamy (1990) style lattice is then developed to solve the partial differential equation for the value of the listing agreement. After identifying various parameters that determine the contract's value, those parameters are varied to examine their relative impact on the contract.     

REITs, IPO Waves and Long-Run Performance

The real estate investment trust (REIT) industry has undergone three waves of initial public offerings (IPOs) since 1980. In this article we examine these waves within the context of the general IPO wave literature. We note that the unique nature of REITs may render them more transparent than other stocks, and that this may affect their IPO performance. Specifically we document the initial and long-run performance of equity REIT IPOs during and after each wave, and we then examine which of the general IPO clustering and pricing theories best fits that performance data. We find evidence of much smaller initial returns than is typically found for non-REIT IPOs. We also find no evidence of the long-run negative abnormal performance for REITs that is normally found for other stocks. Our findings support the idea that the Capital Demand Hypothesis best describes the REIT IPO market, although we also find some weak evidence in favor of the Information Asymmetry Hypothesis. We find evidence against the Investor Sentiment Hypothesis.     

Determinants of Performance for Mortgage-Backed Securities Funds

This article examines the performance of mortgage-backed securities (MBS) mutual funds from January 1987 to June 1995. As a group, the MBS mutual funds underperform both the Salomon and Lehman Brothers MBS market benchmarks. The relative underperformance of the MBS mutual funds is due to poor securities selection and timing decisions. Fund expenses also contribute significantly to the underperformance, while fund load, turnover, management fees and other fund characteristics do not materially affect performance. The underperformance is found to be concentrated in several exceptionally bad months during the sample period. Testing indicates that the MBS mutual funds underperform the MBS benchmark during months of rising interest rates, but match the MBS benchmark during months of falling interest rates.     

Land Development: Risk, Return and Risk Management

We model and examine the financial aspects of the land development process incorporating the industry practice of preselling lots to builders through the use of option contracts as a risk management technique. Using contingent claims valuation, we are able to determine endogenously the land value, presale option value, credits spreads and the effects of presales on debt pricing and equity expected returns. We show that using presales options effectively shift market risk from the land developer to the builder. Results from the model are consistent with the high rates of return on equity observed in empirical surveys; they also suggest that developers may be justified in pursuing projects with substantially lower expected returns to equity when a large number of lots can be presold. Additionally, we show that presales reduce default risk dramatically for leveraged projects and can support a considerable reduction in the cost of construction financing. Large debt risk premiums are justified for highly levered projects, which helps explain the use of mezzanine financing in the land development industry to reduce expected default costs.
