Remortgage with Debt Consolidation

If your client is borrowing to repay a credit card balance and does not clear the balance in full each month, please key the following in the Outgoings section:

  • When asked ‘What’s the total your client owes on all credit cards?’ Enter the full total credit card balance owed.
  • When asked ‘Of this amount how much will be cleared on or before completion?’ Enter the full total credit card balance owed, MINUS £1.

If they do clear the full balance each month, enter the current balance and the total amount to be cleared.
