The present paper aims at exploring rental valuation of business properties. According to Iranian tax laws, rental valuation of properties should be done by a Real Estates Valuation Committee. This committee divides Tehran city into 162 blocks and allocates a rental value/square meters in each block. The present research is firstly aimed at determining indices and factors affecting the rental value of business properties and at presenting an appropriate model for valuation. Then, we test a hypothesis indicating that “the valuation procedure applied by INTA is inefficient” and compare our proposed model with INTA’s method. The statistical population of this research includes all business units acting legally within the geographical area of Tehran. Through some interviews and reviews of literature, we have characterized 16 indices as possibly affecting the valuation of rental value. Then, through developing a questionnaire to be filled up by experts of Tehran City Tax Affairs Organization, 9 indices have been separated as the most important factors. In order to develop the model, after selecting a sample of 383, the 9 indices in question have been measured. Then, in order to develop and validate the intended model, we have calculated the Spearman’s correlation coefficient along with Kendall’s coefficient in the significant level of 0.01 leading to the separation of 6 indices followed by running a linear multiple regression and the administrating the STEPWISE methodology. In the nest stage, estimated rental values have been calculated using both our proposed model and INTA’s methodology. The two sets of values have then been compared against the actual market rental values. The final stage of the research includes testing the “proportion of success” hypothesis (p) as well as testing the hypothesis of “comparison of proportion of success in the two populations” (p1-p2) in order to verify the research hypotheses.
