As part of our regular monthly payment, we have included additional money towards principal pay down. From XXXX to XXXX, besides our normal monthly payment, we have sent {$150.00} specified towards additional principal. However, in the Bank of America statement, the {$150.00} does n't get applied toward principal, instead it gets categorized under " unapplied funds '', then used to reduce our monthly payment. If this is the case, then Bank of America is not applying the {$150.00} towards our principal pay down. We are not aware of any loan terms that say we ca n't make payments towards principal pay down.
