You can also go bank "hopping". In my experience, the quoted rates are not fixed. Go to one bank and get a quotation. Then go to the 2nd bank and show the 1st bank's quotation, tatapatan or bababaan pa ng 2nd bank yung rate nila. You can then go back to the 1st bank or to a third bank. Just be friendly and maintain good rapport with the loan officers or bank manager. Don't commit at first. Good luck!
