While true, there are some markets where these properties are fighting for a very finite supply of tenants. If they see they are lagging behind in their leasing, they really don’t have any other choice than to lower their prices to make sure they don’t have any vacant units. The industry term is called “vacancy loss” and it’s the one thing the upper management money men actually fear. A unit without someone inside it is literally bleeding money from them so they’ll do nearly anything to fill it.
Hopefully soon they won’t be able to share their prices as easily and they’ll have to fight for their lives by lowering prices to fill vacancies before another property snaps them up.
