A property tax depreciation schedule is usually required to be prepared just the once, either each time the property is sold to a new owner or if it has been recently built. Our reports include a twenty year summary of the investor's claim through the initial two decades of ownership. From experience I have found that twenty years is a long enough period to provide the summary as most owners sell or refurbish their properties before then. If any of the property's specifications do change during that time through refurbishments, extensions or demolition, an additional report should be prepared to maximise the eligible allowances. However, if there has not been any specification changes to the property in that time then C2 Developments will gladly prepare an extra report free of charge.
