Assume you rented a house for $2,000 a month. You own the home and it is completely paid off. You also live in another house that is also paid off. Would you quit your job (most likely a higher salary and benefits) to enjoy life and never work again for some money to survive? I would assume a very frugal life.
What happens when you need a new roof, siding, or other maintenance? Houses can be extremely expensive at times.
