If you're the average landlord, you hire people to maintain the building and deal with the tenants. Rich people constantly try to convince everyone that owning things is a job. If buying a business forces you to work operating it, it's because you couldn't afford the business outright, so instead you're paying it off with sweat equity.

Certainly nothing wrong with buying a job, it's positively Jeffersonian, but the reason you're working there is because you couldn't afford anyone else.

Being a landlord is just feudalism. Most of the terminology is still the same.
