SQM Research managing director Louis Christopher.Labor’s proposals include a plan to restrict negative gearing tax concessions to only new properties and halving current capital gains tax discounts for property investors. The plan was first introduced before the 2016 federal election when the market was still booming, but national dwelling values have fallen 6.8 per cent since peaking in October 2017. Were Labor to implement the plan, national property prices would drop a further 4 to 12 per cent over 2020-2022, according to the SQM modelling, but the impact on Brisbane home prices would be minimal. 2020-2022 Home Rents Forecasts.
