My last SRA supervisor told me an acceptable remaining economic life for a newer CB home is 100 years. Her argument being there are plenty of frame homes that are 100+ years old. The default remaining economic life with WinTotal is 60 years. Remaining economic life is the number of years between the date of an appraisal and the date a property improvement will cease to have any economic value, even if it will still be structurally sound. Is she correct? Where does the default remaining economic life from WinTotal originate? Thanks for your help!
