From landlords perspective. things are build with very poor quality materials, that require constant maintenance. Also weather damage of all sorts from trees to roofs, to water in basement. plumbing now made from plastic that leaks. long list. Also people fail to consider how much of the rent money is going to interest, about half over a lifetime. In cities like Toronto, the rent doesn't even cover the mortgage on most rented out houses. So landlord will need to pay the difference, with the hope of getting it back evnetually do to inflation or rising prices.
