The costs of the services aren't the only thing a landlord provides. They also get to deal with the contractors to do work and repairs, and they carry a large amount of financial risk. Not to mention that tenants are typically way more protected than landlords, legally.

You also get the benefit of being able to leave basically whenever you want. With a home you're stuck with it until it sells.

Like I said, that situation doesn't work for everyone, but the truth is that literally any service is going to be more expensive than doing it yourself.

I absolutely know people who sold their homes and rented because paying extra was worth more to them than the hassle of owning.

Also, I did have landlords who would subtract from my rent the cost of hiring a repairman if I did the work myself. It was worth it to them to not hassle with flakey contractors.
