> leech the society for the rest of their lives Would these houses even be built if someone is not paying for them. They are not leeching but investing. May be we could call it leeching when they form a cartel and start raising rent prices in unison (which only biggies like black rock can do).
They invest in housing specifically because there's a bunch of tax avoidance loopholes for small-time landlords. There's nothing wrong with honest investing, but tax breaks are for leeches.
Rarely are they exclusively the second, but landlords get to deduct the economic costs of doing business. Loan interest and property taxes cost money, buildings and fixtures wear out (but the land does not). Maintenance costs money. Landlords have the ability to deduct these costs of doing business against rental income just like every other profit-seeking business does.
Can you name a tax loophole for small-time landlords that you think is improper in the context of a tax system which taxes profits?
