Final answer:
A life estate is NOT a type of lien given to a lender by a borrower as security for a real estate loan.
Step-by-step explanation:
The correct answer is life estate. A lien is a legal claim against a property that is used as collateral for a loan. An involuntary lien is a type of lien that is imposed on the property without the owner's consent, such as a tax lien or a mechanic's lien. A deed, on the other hand, is a legal document that transfers ownership of a property from one party to another. However, a life estate is not a type of lien, but rather a type of ownership interest in a property.
