Cost Approach does work well for New Construction and Manufactured Homes. However, Sales Comparison approach is much more effective way to value a property and I would be shocked if the Assessors are really taking the time to value each property by the cost to construct and then calculating the depreciation for said property, particularly when they only drive by the properties and actually physically inspect a handful.
