A cosigner for a loan is someone who promises to take responsibility for the loan if the primary borrower defaults, meaning they will cover the payments if the borrower fails to do so. This can help the borrower secure the loan by improving their creditworthiness in the eyes of the lender. Interestingly, lending without a cosigner can be a riskier venture for both lenders and borrowers, especially for those with limited credit history or lower credit scores. A cosigner essentially adds an extra layer of security for the lender, which in turn can lead to better loan terms for the borrower.
