On time rent payments to our mortgage co.

[Vickie Cave]

How do we ensure that our mortgage company gets paid by the first of the month? Do we tell our tenants money must be deposited into our bank account by the 25th of the month, so I can make our online payment to our mortgage co? Also, how do they deposit money into our banking account? I don't want them having our private banking account numbers. My husband and I are very new to this and would appreciate any guidance given.
Thanks.
