There is a huge difference between a private owner, and a corporation. Anyhow they might have a common approach, I would say estate ownership should be limited to a certain number through incremental taxation the more you own the larger the tax bracket, like we do for income

I am offended on behalf of the good people I know who made it so we could have housing when we can't afford a mortgage or the housing upkeep costs. They were investments to them sure but they cared about their tenants. Call in the middle of the evening because the toilet wasn't working and they came quickly with a brand new toilet. Couldn't make that months rent till the middle of the month , no problem, pay when you can type thing. Every single landlord aren't the devils you want them to be. I agree some of them are bad because I've had that experience too. I think maybe you should be angry with the banks and the giant conglomerates who pay you shit wages making you too poor to afford a mortgage or the upkeep for home ownership. I am not willing to lump all landlords in the same shit pile. I've seen second hand what being house poor is like. House is falling apart because they can't afford to maintain it. Wearing winter coats inside because the furnace broke and can't afford to fix it, not having a working toilet and shitting in a bucket with a trash bag. Also imagine having to buy a new house everytime you moved to a new town or different area of a big city. Renting a home or an apartment has a place in society.
