Abstract: The existing mortgage
pricing literature either fails to consider the default option or gives numerical results
only. Solutions using numerical methods not only do not provide the intuition of analytic
solutions, but also are very expensive in computation time, since a supercomputer is
frequently required. We, therefore, have employed the Cox-Ross [1976] approach to price a
fixed-rate mortgage with a default option. We are able to provide analytic solutions,
comparative statistics and more simulation results not available in existing models.
