From Brian Bingham:
The eValuator module is a property analyzer that will help you determine the value of a investment property based on income, expenses and your specified annual ROI (return on investment) goal. eValuator also helps you estimate potential management, maintenance, and vacancy expenses. The ROI Calculator module is a property analyzer that will help you determine the annual ROI (return on investment) of an existing investment property based on income and expenses. The Mortgage module calculates a monthly mortgage payment with principle and interest. Version 1.1 has updated the menu options and added the ability to export eValuator calculations to TextEdit for printing and saving.
