That's another excellent observation.
Property developers do not have the luxury of keeping their prices where they are and believing they'll be able to sell or rent their buildings.
Yes, there's a housing shortage, but consumers won't necessarily be able to pay $2,400 a month in rent. The point isn't really who gets to pocket the GST; the point is figuring out whether these proposals get off the ground because either they're financially viable or they're not.
