A secured loan is any loan that requires the borrower to provide the lender with some form of security. In the case of secured loans, the security will be the borrower's property, regardless of whether it is mortgaged or owned outright. Loans secured against property that is already mortgaged are known as second charges, whereas loans secured against a property owned outright with no existing mortgage in place are known as first charges.
