PROBLEM TO BE SOLVED : To provide a real estate development evaluation system for appropriately evaluating the value of a project related with a real estate.SOLUTION : The input processing of various parameters necessary for simulation is operated (a step 100), and the distribution of a predicted sales price after the completion of a project related with a real estate is estimated, based on the inputted parameter (a step 102), and the amount of a loan and its contractual interest rate are calculated under the consideration of a default risk, based on the distribution of the predicted sales price (a step 104), the amount of a bond and its face value interest rate are calculated under the consideration of a default risk, based on the distribution of the predicted sales price, the contractual interest rate and the amount of a loan (a step 106), and the price of priority investment is calculated, based on the distribution of the predicted sales price, the contractual interest rate, the amount of a loan, the face value interest rate and the amount of a bond (a step 108), and the value of a project is calculated, based on the amount of a loan, the amount of a bond and the price of priority investment (a step 110), and the processing result is output (a step 112).COPYRIGHT : (C)2006, JPO&NCIPI
