Which of the following options best describes the purpose of a cosigner?

The primary purpose of a cosigner in a mortgage agreement is to help the primary borrower qualify for better loan terms. A cosigner is typically someone with a stronger credit profile or a higher income who agrees to take on the responsibility of the loan alongside the primary borrower. This additional support can enhance the borrower’s chances of being approved for the mortgage, as lenders consider the financial strength of both parties when assessing the risk of lending.

When a cosigner signs the mortgage documents, they are essentially vouching for the primary borrower's ability to repay the loan. This can lead to more favorable borrowing conditions, such as lower interest rates or reduced down payment requirements, as the lender sees less risk in extending credit with an additional qualified individual backing the loan.
