Why?
I live in a city that is celebrated for its housing schemes, and corporate owned property makes up a good percentage of the housing stock (both private rental, and majority ownership of Genossenschaftswohnung, which is a corporate/renter co-op scheme)
There are various rented flat types in Vienna ranging from privately owned to subsidised and city-owned flats. For the latter two you have to meet certain criteria to be able to rent them.

EDIT
I live in a 2 bedroom apartment that costs €1080 per month to rent. It's privately owned.
An equivalent Genossenschaftswohnung would be around €650 per month to rent, but demand is extremely high and I think as a couple we earn above the income threshold to qualify for one actually.
Look to the USA to see what else can happen when you allow corporates to take over entire neighbourhoods. In places they bought up everything in sight and then increased the rents to eye-watering levels, because they saw how controlling the entire market in an area could be extremely profitable.
I guess you could say they can only charge what the market will bear, but again, it only serves move money from the working classes to the rich and/or shareholders. And again, people are being priced out of areas or finding that they'll be paying a massive chunk of their wages to their landlord. Also in that case the properties are no longer available to own, only to rent.
A lot depends on the regulations and the rights that renters have. Scotland and England differ in that regard. If rent was no more than 20% of your income, and you had long-term residency rights, perhaps a lot more would choose to rent, and not worry so much about owning a home.
Much of this debate depends on your overall attitude towards capitalism in the modern era (so-called "late-stage capitalism"). Where, in this country at least, we appear to be ramping up the "greed is good" rhetoric beyond all reason, and decrying any kind of restraint as socialism and state interference. Honestly, with the increase in relative poverty (inc. in-work poverty), homelessness, general discontent amongst young people with no hope and no stake in the future of this country, it's hard to see how we're not going to end up with mass civil unrest.
We're having a small taste with the ongoing strikes due to the temporary spike in inflation and energy prices. But that's also very much the long-term trend. At some point, people will stop accepting the continual squeeze, when they can clearly see we're not "all in it together", and the squeeze is simply the people above them taking more and more and more.
Maybe it'll take a few more years to come to the boil, but the current trends are not sustainable. For starters, almost everyone agrees that the housing market is not fit for purpose.
