Final answer:
A mortgage bond is secured by a lien on real property.
Step-by-step explanation:
A mortgage bond is secured by a lien on real property. This statement is true. When a person takes out a mortgage loan to purchase real estate, the mortgage bond is created as a legal instrument that gives the lender a claim on the property in case the borrower defaults on the loan. By securing the bond with a lien, the lender has the right to foreclose on the property and recover their investment if the borrower fails to repay the loan.
