My experience with Amerisave Mortgage has been a PAIN IN THE ASS!!
Took them 11 months to close the loan because of them mistyping SSN, requesting the same documents over and over, and were not communicating with me.
After the loan was finalized they included payment coupons with the wrong account number, wrong address, and wrong phone number.
After making payments successfully with automated BillPay app for several months they changed the security and blocked and BillPay app payments. When I called for support they said BillPay apps no longer work and have to mail a check or make payments from their website.
