Yes. The deposit makeup payment is due at the same time
as the first month rent in the renewal period. My state allows us to charge last month rent. I require tenants to make up that amount to the new rent number. Last month and deposit payment is our leverage against tenant's default. They can be applied to the unpaid rent and court cost in case of eviction, hence to significantly reduce landlord's financial loss.
旧人可以签addedum，因为租约正文上有他们的签字，说明他们受原租约约束。
如果你加了一个新人，就不能用addendum，因为新人没有见过旧租约没有在上面签过字。
所以如果ABCD续约成ABC，可以用addendum。如果ABCD变成ABCE，那么ABCE需要重新签新租约。
ABCD的押金，一个人搬走了就都要还给ABCD，再让ABC或者ABCE付新押金。
如果ABCD一起续约，你不必退押金也不必收新押金。
这都是业务水平啊。
