In a positive context, asset valuation models may be judged on the basis of their predictive ability rather than on the number and elegance of the underlying assumptions. The Average Daily Rate (ADR) rule-of-thumb has been used for decades as a quick way of estimating hotel and motel room rates and, more recently, as a simple gross-income multiplier model for predicting values of lodging properties. This study examines how well the ADR rule-of-thumb model predicts property values. The results of our comparative analysis of estimates from the ADR model with those from a hedonic valuation model indicate that the ADR model performs well in the aggregate, but is an inconsistent estimator at various levels of disaggregation, such as when property subsamples were organized by number of rooms, age, occupancy rate and number of restaurants.
