Stricter guidelines on sub-prime mortgages
The main difference between prime and sub-prime mortgages lies in the risk profile of the borrower; sub-prime mortgages are offered to higher-risk borrowers. Specifically, lenders differentiate among mortgage applicants by using loan risk grades based on their past mortgage or rent payment behaviors, previous bankruptcy filings, debt-to-income (DTI) ratios, and the level of documentation provided by the applicants to verify income. Next, lenders determine the price of a mortgage in a given risk grade based on the borrower’s credit risk score, e.g., the Fair, Isaac, and Company (FICO) score, and the size of the down payment.
