How we compare rents

We compare the same identified apartment within one listing period. Asking rent, fees, and promotional effective prices remain separate. Repeat checks must confirm a comparison. A missing price is never counted as an unchanged rent. Large events need additional checks before we publish a story. Prices update after successful checks.
