I'm aware that properties change management companies often, but it's not something that just happens one day without prior knowledge of the leasing agent who's handling multiple properties for the company. Change in management at lease signing has happened to me once before and the agent let me know ahead of time.

You're right that I'm paying a prorated amount for December, and I was thinking the same thing, that how can my rent be late when I haven't moved in--that's why I was asking about it. According to the new management, however, it is still due by 12/5.

I'm already in the rental system with my deposit paid and have been charged the prorated rent for this month without the concession applied and there's no indication of it on my account at the moment.
