Although I agree with the sentiment - I am curious how the system works with landlords having so many unoccupied units in some cities. Especially business/commercial/industrial landlords. It keeps rent artificially high, while reducing some types of overhead I would guess.
How does the business of being a landlord not work out to a “yes and” solution? You could make money on rent and sell at a later date. Is risk too high due to the cost of proper upkeep when a unit is occupied? Is it the cost of management?
