I mean taxation can be a strong correcting force when applied well.

For example, exponentially increasing the property tax on housing that you don't live in for a minimum of four months out of the year.

Doesn't sound too exciting, but landlords would basically be limited to three properties before the economy of scale made hoovering up the entire local housing market impractical, and it also severely puts the rates up on company landlords since it is not possible for them to live in any property, only operate out of one.

End result, massive flood of units onto the open market, lowering housing costs, and costs of living by extension since those usually rise with housing prices as well.
