Abstract: This article seeks to
answer why over a nineteen-year period the debt-coverage ratio for commercial noninsured
properties averages 1.29. The article applies the corporate liabilities extension of the
Black-Scholes option pricing model to the equity valuation of a real estate project. The
regression results of the modified model robustly sustain its usefulness in explaining the
derivation of the debt-coverage ratio. The results confirm that commercial mortgage loan
underwriters operate with a five-year horizon in creating the equity cushion needed to
protect themselves against interest-rate risk.
