High-risk mortgages have facilitated those with low credit scores to become homeowners. Subprime loans can be of the high risk variety. Subprime loans are typically mortgages to borrowers with credit scores of 620 or below. With a low credit score, lenders typically must charge a higher interest rate. Interest rates charged on a subprime loans are typically adjustable-rate mortgages (ARMs). A garden-variety ARM has a low interest rate period for the first two or three years. However, after the introductory period, interest rates go up resulting in higher monthly mortgage payments.
