Highly unlikely due to the number of uncertainties, as discussed by Iggy Damiani for Sky News Business in this short video.
The video cross-references some of the data from my post here (4 reasons negative gearing won't be squashed).
And indeed it won't be, with the blunt answer coming straight from the top.
From the AFR:
"Prime Minister Tony Abbott has put an end to speculation over the future of negative gearing by promising there will be no changes.
When asked on Thursday whether he could rule out changes to negative gearing, Mr Abbott gave a blunt answer: "Yes."
Think I'll leave others to continue the ongoing debate now.
