It's primarily an indirect effect. Landlords won't buy/build new houses if the expenses would be too high relative to the rent the market is willing to pay. That lowers the supply and raises the rents in the long term. However, if you have an existing property, there are no guarantees that you can find a tenant who is willing to pay enough to cover your interest, taxes, and other expenses.
