Sort of a “Cobra Problem” of rental agencies, wherein they have an economic incentive to show you a few duds before they get you anywhere near some place you’d want to live in.

Incidentally, this is already a strategy rental agencies. Exhausting your client in a run-around means they’re more likely to settle on a mediocre choice than hold out for something better. Stapling a price tag on every new visit means further disincentivizing them to keep looking after you’ve showed them a bunch of lemons.
