Good theory.I don't really know how that addresses the equation as those people are still part of the rental pool.
Break it down to a group of 10 people.
7 own their own home
3 are living in rented investment properties owned by first group
1 house is being built
If negative gearing changed and one of the rental property owners decided to sell and is purchased by the tenant then there is still only a current demand for the 10 properties, it's just changed from 70% ownership/30% renting to 80%/20%.
You still have the house being built to cater for new demand.
As already suggested in the thread, the impact from rents rising would come if new supply was disrupted by the changes, but as I already pointed out, the number of negatively geared investors building new houses is small.
I think a change to negative gearing would be best for all if it was removed for existing properties (not in one hit) and only allowed for newly constructed homes (perhaps with a limit of first owner of new home only and first 5 years). This would encourage investors to contribute to new supply, rather than speculate on and contribute to the price rise in established homes.
If you give investors only the incentive for neg gearing on new builds, all you'll see will be a spike in prices on new builds, and you just know that the developers will be capitalising on that change to the game in an instant.
As is always the case; your comments are the same as all the other people who are not property investors who think NG is unfair.
It's only unfair if you're not in it, I suppose.
Me; I reckon it's a bloody purler - I get to take an NG property and turn it into a pos cashflow one....nice.
But then, if I'd sat on my fat @rse and never bought anything, I would prolly be a whinger about the rules too.
I guess you can whine, or make your own luck.
