Easy! To start, a high credit score will give you a lower interest rate on your mortgage. Mortgage data indicates that a 760 credit score will lock you in at 5.11% interest on a 30 year fixed mortgage. A 700 credit score would give you 5.33% and a 620 would be close to 6.42%. The higher your credit score, the lower interest you have to pay. With the money that you are saving on paying less interest you can invest it in an interest baring account. If your monthly investment is $250 with a 10% interest rate you're looking at making @ $189,842 after 20 years and @ $1,581,019 after 40 years. It is a common fact that higher credit scores will help you qualify for credit cards and loans, but the higher it is, the more you can save and see those savings actually make you money! If your credit score isn't as high as you would like it to be, a credit repair specialist can see if credit repair is right for you. Often times there are mistakes and errors on credit reports which can unnecessarily cause your score to be lower than it should.
