G'day, Have a question, can't seem to find anything with the search function: IP bought early 80s, was subdivided early 90s and new house built IP also (battle axe block). Looking to sell the original house now, keep the newer 90s house for now. What are the tax implications? Broadly. My uneducated guess was, need an appraisal/valuation at time of the subdivision for land component of the new block, the new house build and that land val forms the cost base of the new property and the old house should be still CGT free??
