When you initially start shopping for a home mortgage, you may be drawn to advertisements for ultra-low interest rates. These may be rates that seem too good to be true, and you may gladly contact the lender or mortgage company to complete your loan application. However, in many cases, mortgage applicants are unpleasantly surprised and even disheartened to learn that they do not qualify for the advertised interest rate. By learning more about the factors that influence your interest rate, you may be able to structure your loan in a more advantageous way.
