The mortgage industry is highly competitive, but rates aren't arbitrary. Lenders use math and risk assessment to set them: the lower your perceived risk of default, the better your rate. High risk? Higher rate—or possibly denial.
Published rates are starting points. Lenders then apply adjustments based on your profile—some raise your rate, others lower it. Mastering these factors puts you in control and can save thousands over your loan's life.
