Property Securities are financial instruments that are used to secure a loan or other debt. They are typically backed by real estate, such as a house or land, and can be used to secure a loan or other debt. Liens are a type of Property Security that is used to secure a debt against a property. A lien is a legal claim against a property that gives the lender the right to take possession of the property if the debt is not paid. Liens are often used in mortgages, where the lender has the right to take possession of the property if the borrower fails to make payments.
