The municipality can set the rent. I know of cases where: - it's high to have lower taxes for the rich for no reason, making private schools very competitive because they can just change building. - it's zero, making it very hard for a good private school to compete because they can't never get the rent to zero on the open market. Both these are bad in different ways.
