.- you can use any part of the HELOC  you want to ...make sure the lender you are  using for the new loan will be able to  qualify you with the  HELOC  funds  being used  (  some  lenders will  use the  actual payment on the  outstanding  balance and  other lenders  might use a percentage off the entire HELOC max limit )

Test and refine your communication plan—it pays off!
