This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I develop a rational mortgage valuation model and use the model to estimate parameters describing borrower mobility. The valuation model extends previous work in two ways. First, I calculate the prepayment boundary by solving for the borrower's optimal prepayment strategy over the expected tenure in the house. This optimal strategy is significantly different from the strategy traditionally used in rational mortgage valuation and the resulting mortgage values are higher than values calculated using the traditional approach. Second, I use borrower heterogeneity in terms of expected tenure in the house to overcome two problems typically associated with rational models: all-or-nothing prepayment and a low upper limit on calculated mortgage values. I use the resulting model and observed prepayments to estimate the distribution of expected tenure of borrowers who chose a long-term, fixed-rate mortgage. The empirical results indicate that the average mobility of the group of borrowers choosing fixed-rate loans has declined since the introduction of adjustable-rate mortgages.

This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the optimal recursive refinancing problem where a borrower minimizes his lifetime mortgage costs by repeatedly refinancing when rates drop sufficiently. Key factors affecting the optimal decision are the cost of refinancing and the possibility that the mortgagor may have to refinance at a premium rate because of his credit. The optimal recursive strategy often results in prepayment being delayed significantly relative to traditional models. Furthermore, mortgage values can exceed par by much more than the cost of refinancing. Applying the recursive model to an extensive sample of mortgage-backed security prices, we find that the implied credit spreads that match these prices closely parallel borrowers' actual spreads at the origination of the mortgage. These results suggest that optimal recursive models may provide a promising alternative to the reduced-form prepayment models widely used in practice.

Available in PDF, EPUB and Kindle. Book excerpt: Mortgage-backed securities (MBS) are among the most complex of all financial instruments. Analysis of MBS requires blending empirical analysis of borrower behavior with the mathematical modeling of interest rates and home prices. Over the past 25 years, Andrew Davidson and Alexander Levin have been at the leading edge of MBS valuation and risk analysis. Mortgage Valuation Models: Embedded Options, Risk, and Uncertainty contains a detailed description of the sophisticated theories and advanced methods that the authors employ in real-world analyses of mortgage-backed securities. Issues such as complexity, borrower options, uncertainty, and model risk play a central role in the authors' approach to the valuation of MBS. The coverage spans the range of mortgage products from loans and TBA (to-be-announced) pass-through securities to subordinate tranches of subprime-mortgage securitizations. With reference to the classical CAPM and APT, the book advocates extending the concept of risk-neutrality to modeling home prices and borrower options, well beyond interest rates. It describes valuation methods for both agency and non-agency MBS including pricing new loans; approaches to prudent risk measurement, ranking, and decomposition; and methods for modeling prepayments and defaults of borrowers. The authors also reveal quantitative causes of the 2007-09 financial crisis and provide insight into the future of the U.S. housing finance system and mortgage modeling as this field continues to evolve. This book will serve as a foundation for the future development of models for mortgage-backed securities.

Download or read book Mortgage Default and Mortgage Valuation written by John Krainer and published by DIANE Publishing. This book was released on 2010-10 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors develop an equilibrium valuation model that incorporates optimal default to show how mortgage yields and lender recovery rates on defaulted mortgages depend on initial loan-to-value (LTV) ratios. The analysis treats both the frictionless case and the case in which borrowers and lenders incur deadweight costs upon default. The model is calibrated using data on California mortgages. Given reasonable parameter values, the model does a surprisingly good job fitting the risk premium in the data for high LTV mortgages. Thus, from an ex ante perspective, the authors do not find strong evidence of systematic underpricing of default risk in the run-up to the housing market crisis. Charts and tables.

Available in PDF, EPUB and Kindle. Book excerpt: This article presents a new model of mortgage prepayments, based on rational decisions by mortgage holders. These mortgage holders face heterogeneous transaction costs, which are explicitly modeled. The model is estimated using a version of Hansen's (1982) generalized method of moments, and shown to capture many of the empirical features of mortgage prepayment. Estimation results indicate that mortgage holders act as though they face transaction costs that far exceed the explicit costs usually incurred on refinancing. They also wait an average of more than a year before refinancing, even when it is optimal to do so. The model fits observed prepayment behavior as well as the recent empirical model of Schwartz and Torous (1989) Implications for pricing mortgage-backed securities are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Mortgages are complicated instruments, and the pace of financial innovation complicates them further. Unlike standard single family mortgages, the terms on commercial loans are heterogeneous, and the motivations of property owners are not well understood. Single family lenders are increasingly adopting the prepayment penalties found in the commercial market. This paper fills in a gap in the study of mortgage finance by determining the optimal refinancing strategy under common forms of prepayment penalties. Our paper uses a bivariate binomial options pricing technique to value call options within various mortgages with different types of prepayment penalties. Using simulations, we calculate the spread between contract and prevailing interest rates needed to trigger an optimal refinance, and find that it is often substantially larger for mortgages with declining penalties than for mortgages with static penalties. The larger required spreads caused by the enhanced value of delay explain much of the slow prepayment behavior discovered in the multifamily market by Follain, Ondrich, and Sinha (1997). Therefore, borrower decisions which appear slow (or irrational) in a static setting may be quite rational in a dynamic setting. Our results have important implications for both the interpretation of regression results based on historical data, and for the pricing of newly originated mortgages. Declining prepayment penalties were used extensively for multifamily mortgages in the 1970's and 1980's. While their use has declined in the 1990's in favor of yield maintainance agreements, empirical studies which use 1970's and 1980's data need to incorporate the effects of these penalty structures or risk specification bias. At the same time that their use is declining in the multifamily market it is growing in the single-family market. Understanding the behavior of these mortgages will be crucial to their pricing.

Available in PDF, EPUB and Kindle. Book excerpt: While option-theoretic models are widely used in valuation of other fixed-income instruments, their applications for the valuation of mortgage-backed securities face challenges. Mortgages are explicitly written with a call option, which allows mortgagors to prepay their mortgages any time before the maturity. The magnitude and timing of exercising the prepayment options are not purely driven by economic factors, but also the mortgagor's individual preferences and personal behaviours. This brings difficulties to valuing mortgage-backed securities with conventional models. In this thesis we aim to explore the prepayment risk caused uncertainties in valuation of mortgage-backed securities. We start with empirically examining an option-theoretic model proposed by Kalotay, Yang and Fabozzi (2004). This model has special features to treat borrower heterogeneity and suboptimal exercises of the prepayment options. Based on the empirical results, we propose to employ linear prepayment functions to model borrower heterogeneity. The new MBS valuation model with the integration of linear prepayment functions is also tested with empirical data. Our results suggest that mortgages with different coupon rates have different refinancing tendencies even towards the same market rate change. Therefore, assuming the same refinancing pattern to all classes of mortgages may lead to errors in pricing mortgages and MBSs. For mortgages with coupon rate below the prevailing refinancing rate (as proxied by the 30 year libor rate) plus the refinancing cost, a prepayment function with a low initial prepayment rate and a high slope will model the prepayments best. On the other hand, for mortgages with coupon rate above the current refinancing rate plus the refinancing cost, a prepayment function with a high initial prepayment and a mild slope will perform best. Meanwhile, refinancing burnout is also an important factor in modelling mortgage prepayment. Our results suggest that when the underlying mortgages are seasoned mortgages, especially when the prepayment option has been deep-in-the-money for a long time, the low initial prepayment high slope function will model their prepayments the best. Once these different refinancing tendencies are factored in the modelling of mortgage prepayment, the accuracy of the MBS valuation model is greatly improved.

Download or read book Why Do Borrowers Make Mortgage Refinancing Mistakes written by Sumit Agarwal and published by . This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refinancing a mortgage is often one of the biggest and most important financial decisions that people make. Borrowers need to choose the interest rate differential at which to refinance and, when that differential is reached, they need to take the steps to refinance before rates change again. The optimal differential is where the interest saved by refinancing equals the sum of refinancing costs and the option value of refinancing. Using a unique panel data set, we find that approximately 59% of borrowers refinance sub-optimally - with 52% of the sample making errors of commission (choosing the wrong rate), 17% making errors of omission (waiting too long to refinance), and 10% making both errors. Financially sophisticated borrowers make smaller mistakes, refinancing at rates closer to the optimal rate and waiting less after mortgage rates reach the borrowers' trigger rates. Evidence suggests borrowers learn from their refinancing experiences as they make smaller mistakes on their second refinancing than on their first one.
