Where the borrower may add to the principal without renegotiating the terms of the loan. Additional sums borrowed under the terms of an open-end loan will have the same rate of interest and life of loan terms as the original loan. Quite frequently a home equity loan is an open-end loan, and the borrower may add to its principal without changing its terms.

Thus, he increases the principal of the home equity loan by an additional $5,000 to make the necessary repairs without changing the terms of the loan.
