Abstract: A method for providing service users with occupancy cost comparisons between a plurality of commercial leased properties includes the steps of: (a) defining an occupancy cost parameter for a leased property, (b) providing an interface for service users to input into a searchable database the identifying property information and the specific lease terms required to compute this occupancy cost parameter for each of the leased properties, (c) providing an algorithm that utilizes the inputted specific lease terms information to compute the occupancy cost parameter for each of the leased properties, (d) utilizing the occupancy cost parameters to create a fiduciary-responsibility-abiding (FRA) lease comp for each of the leased properties, and (e) storing in the database the FRA lease comp for each of the leased properties.
