A top-rate taxpayer with two investment properties would be about $19,000 a year worse off under the Labor Party's plans to limit negative gearing. Does that mean property investors should be running for the hills, or that potential investors should buy before the changes?

No, because it's been suggested any changes would be "grandfathered", meaning investments existing before July 1, 2017 would be exempt. And it's looking highly unlikely that Labor will win the next federal election.
