But that's the intended outcome, isn't it? The proposal is to increase supply of housing for sale by decreasing of supply of housing to rent.

The cost of investment increases, so to keep the profits investors increase the rent, less people can afford it so the demand for rent decreases and investors sell houses. The supply of housing increases (I agree this is quite convoluted way to increase housing supply) and prices drop. Top cohort of renters can now afford to buy a house, and the bottom cohort is... fucked?
