Apartment rent paid by automatic withdrawal from our checking account?
Read your lease agreement. It is a binding contract. See if they have any clauses in effect, where they can change the method of payment. There usually is a clause about them notifying you 30 days before any changes they make to anything. My apartment complex obtain new owners, who required that we mail in our payments, we could no longer pay them at the rental office. They notified us of the change in writing.
