As the vacancy rate is widely reported for most urbanized areas, it can be subtracted from EVR to arrive at the expense rate. This Demonstration provides actual GRM and CR data for six major U.S. cities, derives the EVR, and allows the user to specify a level of vacancy to be deducted. The empirical CDF places the expense rate in a probability context. As one would expect, low expense ratios used to balloon CR to an unrealistic level are improbable.
