I believe that there is merit to the theory. If you bought a house 5-7 years ago, the interest and taxes is half of what it cost to rent a smaller house in the same neighbourhood. The high rent is not driven by demand, nor by cost. It's for profit or pretty numbers that mean higher sales value. There is already a form of renting companies that is supported by law, preventing this. They are called "Almenyttig boliger" and is required to be a non-profit company. They are more akin to what americans know as a credit union, just for housing instead of financial activities. About a quarter of all homes are of this kind. Still we have seen investment conglomerates buy large properties and "renovate" them and then raising the rent significantly. I say renovate in quotes, because it's the bare minimum to live up to the law allowing them to raise the rent. The raise is always significantly higher than the value of the renovation, to the point where the politicians had to make new laws trying to get it to stop.
