The corporations are buying and renting because it makes business sense. If we just keep building houses, the market values for rents and home prices will reach an inflection point. Investment companies aren't going to keep buying houses if they have a high vacancy on existing stock, they're going to start selling houses or lowering rent.
The fundamental problem is "too little supply". Regulating the demand side is at best a bandaid. The solution is to change regulations to allow faster, cheaper, easier building until the equilibrium market price of housing is something reasonable.
There are structural problems with the demand side that also need addressing.
It only seems that way because in many popular metros around the country, demand has far outstripped supply for decades.
The problem is "solved" in areas that aren't as popular, with zero regulation on who's allowed to purchase homes; ordinary people can buy ordinary homes on ordinary incomes. But aspirational young people don't tend to move to such areas.
Why has this been the case in every area in our country? Because we have a policy at the national level that encourages speculation and hoarding. The problem is not just supply, we have a national aversion to shaping demand.
> The problem is "solved" in areas that aren't as popular,
The problem is absolutely not solved, in any place in our country[1]. You used to be able to maintain a minimum standard of living on a single wage earner's salary. That is not the case, literally anywhere in this nation any more.

Raising interest rates may help too. How many of those purchases are financed? I'm guessing a lot. The commercial side got screwed when they needed to refinance underperforming properties at higher interest rates.
"Buying an entire development" is arguably anticompetitive behavior and can be prevented by the government.
My city's housing development department is run by the Chairman's (our version of a Mayor) nephew, the husband of a previous member, an owner of the largest property management company in the county, and an owner of a landscaping business. I attempted to join the housing development department but the positions are specifically appointed by the "Mayor". Our "Mayor" is also not elected via public voting, since they are a Chairman they have to be removed by the Board, and the Chairman has held this role since 1975.
Ultimately, until this Chairman passes or is (somehow) removed from their role, there is nothing that anyone in our city can do to rectify this. And I believe this is a common problem across many cities outside of Metro areas (where the housing supply issue is more apparent).
It's a terrible local government, but right now I'm not in a position to move anywhere else without ending up driving 3hrs a day to go to work and paying way more than I can afford.
The medium and small lot houses have a no rental stipulation. I forget the exact terms but the houses have to go to individual owners and there's some residency requirements before you can offer it as a rental.
Speculation is a symptom of price issues, not a cause.
Which is why "just build more housing" isn't really working, because you can't just overbuild human demand (we already do that in lots of cities, especially in the midwest), you'd also have to also outbuild the entire public and private investment appetite for housing, which is effectively unlimited at the moment.
I always see takes about how the only solution out of a housing crisis is "building more housing" and not any sort of control or regulation over the accumulation of housing stock. But yeah, when even new construction is immediately snapped up... I mean, is there anything to do but regulate the buying side?
