Hi, I recently sold a property and am having some minor difficulties calculating the CGT. I inherited a property worth $350K (land valued at $250K, building at $100K) back in 1984. I spent $200K on an extension to the bulding in 1986. I sold it in December last year for $800K (land $500K, building $300K). I'm aware of the pre 20 Sep 1985 rule, however how would the extension whih was done after this date affect my position? Do I have to apportion the extension against the initial value or sale?
