i honestly don't care if you're a "good landlord" or not, making any kind of profit that you personally benefit from by exploiting others over a basic need is scummy
owning property just to sell it back to people in the form of renting is scummy
yes, even if you're using that money to pay medical bills or donate to charity or something, you're still taking money from folks who probably have less than you, money they now can't spend on their other basic needs and wants
