Owner’s Equivalent Rent for measuring housing inflation is the clowniest, most useless way of computing that in the universe. Owners mostly have no goddamn idea how much it’d cost to rent their own place. I bet if you asked (and the gummint does) the owner and compared that to the actual rent they could get those owners would be off by 40%+.
Maybe the various levels and layers of wrongness balance out. But I doubt it. And even if so, why should we depend on that? Just a terrible, terrible metric.
