Another house in our development recently sold at auction. The price has just gone online. It sold for $A850k. The original sale price when new was $A735k. Our house originally sold for $A650k. Using the same percentage increase our house would be worth $A752k. We paid $A740k. But I have been valuing it at $A785k based on the valuation we got prior to buying. Not sure if I should lower the carrying value to $A750k?
