In real estate finance, an open end mortgage is a mortgage that allows the mortgagor to borrow additional funds under the same mortgage instrument after the initial loan has been made. The additional advances are secured by the same property, subject to the conditions stated in the mortgage agreement.
These conditions often relate to the value of the property or the borrower’s equity and creditworthiness. Open end mortgages provide flexibility for borrowers by eliminating the need to create a new mortgage for each additional loan, while preserving the lender’s security interest in the property.
