Collateral explained
Collateral is something of value that a borrower offers a lender as security for repaying a debt. If the borrower fails to repay, the lender has the legal right to seize the collateral to recover what is owed. This security is what defines a secured loan.
In a mortgage, the property being financed serves as the collateral. The lender registers a charge against the title, giving them a claim on the home. Because the loan is backed by real estate, mortgages typically carry lower rates than unsecured borrowing.
