The catch here is that the people who first get to buy that property usually already have tons of money and just use it as an investment, either to resell, rent it out, or use it for AirBnB & such. Solving that problem isn't very straightforward.

Where I live, for example, the government has been debating taxing non-first properties up to 50% (the yearly real-estate tax). The idea of the proponents is to make it so unaffordable to own more than one property that people would stop buying it as an investment or sell off existing ones. But the issue is that the people who already own that estate (or have the money for more) would still be better off by just raising the rent to cover the increased tax instead of selling it. So it once again fails those who end up paying the rent.

The only real solution seems to be government-funded developments with restrictions put in place on who can buy them, rent them out, etc. But to do that the government has to afford it somehow. They also need to put size minimums in place, otherwise we end up with the same just studios situation, which seems to be a thing with a lot of public-funded developments (perhaps because then the politicians can claim they "built X flats"?).
