Not necessarily. The market will ultimately dictate what a landlord can charge for rent .. if that includes their cost of repairs + taxes, good for them. It's by no means a guarantee, and landlords can go through periods of being cash-flow negative on a property.

The person was commenting on renting vs owning, so I assumed they were talking about the house they lived in (vs renting it out to someone else). When comparing the costs of renting to owning, the "extra" costs of owning a house (taxes, maintenance, insurance, etc) add up to a considerable sum, generally.
