Answer:
A co-signer adds someone responsible to pay the debt in the event you cannot. Direct deposit and funds transfersmay be stopped at any time and are not either collateral on a loan or an alternative source or repayment.
Each lending institution will have it's own underwriting criteria. You may want to try another lender willing to accept the risk that your application has.
