Additional Security Fee
An additional security fee is an up-front, one-off fee paid to the lender to protect against the borrower defaulting on the loan.
It is a form of additional security usually charged on mortgages of more than 75% of the property value.
Occasionally the lender may require a parent to be a guarantor or for other security such as shares or insurance policies to be pledged.
