Why is that a problem to be solved to go socratic about it? A single extra home rental being less profitable will exist "naturally" as a matter of economies of scale essentially with fixed cost component redundancy. Income inequality and imbalance of market influence (if one person owns 90% of real estate their high level of control can't even be called disproportionate because they actually do have that large of a stake) seem like issues better addressed by straightforward income taxation and antitrust respectively.
