Credit scores range between 200 and 800. Scores above 620 are considered desirable for obtaining a mortgage. These factors will affect your score.
- Your payment history. Whether you paid credit card obligations on time.
- How much you owe. Owing a great deal of money on numerous accounts can indicate that you are overextended.
- The length of your credit history. In general, the longer the better.
- How much new credit you have. New credit, either installment payments or new credit cards, are considered more risky, even if you pay promptly.
- The types of credit you use. Generally, it's desirable to have more than one type of credit—installment loans, credit cards, and a mortgage, for example.
