That sort of makes sense. When you own a property, you have to maintain it and pay property taxes. When you add all that up, you either need a lot more than rent, or you need the mortgage to be lower than rent so you can afford those other expenses.
It makes absolute sense, because maintenance costs are non-negligible. I just paid a fifteen thousand dollar plumbing bill. Since rent would include the ability to call the landlord to make him fix that, I sure would expect rent to be higher for the same place than my mortgage is. Last year I spent twenty grand on a new roof. What's next? Idk, but that's why my mortgage isn't half of my salary. If it was rent, these…
That has to be for commercial real estate, or you've been ripped off. There is no possibility of a single family dwelling ever having plumbing problems of that scale.
But maintenance costs are in general a landlord lie. They wouldn't rent out their properties if costs where anywhere near income. As for my own anecdote, my landlord has spent at most 0,5% of what he's gotten in rent from me on maintenance over the years. A normal tenant won't break anything or induce any maintenance costs.
