I don't think I made up the idea that landlords generally don't lose money renting their property. Higher taxes might reduce their profits in a competitive market, but renters are still paying the property tax for the landlord. Tax incidence theory also leans pretty heavily on the assumption that there's healthy competition in the rental market. In most major cities that's a very unsafe assumption.
