I accept the premise on the math, but "better off" is subjective. I'm in the UK so that's my context.

When your renter informs you of the boiler breaking, or a roof needs replacing, that's going to get thorny - "It was fine when I was using it/living in it, did you break it?"

Perhaps the latest round of updates to property law for renters come along and suddenly as a landlord you have to above and beyond what you need to as an owner; you both have to do X, Y or Z to your properties because they're rental and not a basic owner situation.
