This comment doesn’t make sense. Are you using condos to refer to properties with shared walls where the whole building (and land) is owned by the condo owners? If so, then there is no landlord getting a big payday. Condo expenses are what they are because taking care of a big building is expensive, but also because the condo board sometimes defers maintenance for many years or decades, and then the problems become expensive to fix.
