I have a Loan ( Mortgage ) with Green Tree and they charge a {$12.00} fee even if automatic payments are set-up directly from the bank account. For example I called to set-up my automatic pymts. and they told me that every month they are going to charge me a {$12.00} fee in addition to my mortgage payment. The only way to avoid the fee is by mailing a check every month, and again as they said, that is not a secure method because the check can be lost in the mail. We are in 2015 and I do n't consider the {$12.00} fee fair to Green Tree 's costumers. Just multiply {$12.00} fee for 30 yrs!
