Attaining a perfect credit score of 850 isn't easy; after all, that's like graduating from college with a 4.0! Luckily, all scores of 760 and above are considered to be in the best credit score range. If your credit score is in this category, then CONGRATULATIONS! You've obviously done some things right to get it there! As a result, lenders really want your business and will therefore offer you their best products at their lowest interest rates.
Of course, many of us aren't perfect! In that case, a good score is one that falls between 700 and 759, while a fair score is between 650 and 699. A lower score means you’ve had some dings on your credit history. The lower the score, the greater risk you are in the eyes of the lender. You will likely still qualify for a mortgage, but will probably not receive the same rate/cost structure as people with the highest scores.
