The most widely used credit scores are FICO scores, which were developed by Fair Isaac & Company, Inc. Your FICO score is between 350 (high risk) and 850 (low risk).
Credit scores only consider the information contained in your credit profile. They do not consider your income, savings, down payment amount, or demographic factors like gender, race, nationality or marital status. In fact, the fact they don't consider demographic factors is why they were invented in the first place. Credit scoring was developed as a way to consider only what was relevant to somebody's ability to repay their debt.
Credit and number of inquiries are all considered in credit scores. Your score considers both positive and negative information in your credit report. Late payments will lower your score, but establishing or reestablishing a good track record of making payments on time will raise your score.
Different portions of your credit history are given different weights. Thirty-five percent of your FICO score is based on your specific payment history. Thirty percent is your current level of available credit. Fifteen percent is the time your open credit has been in use and types of credit available to you. Finally, five percent is pursuit of new credit.
Your credit report must contain at least one account which has been open for six months or more, and at least one account that has been updated in the past six months for you to get a credit score. This ensures that there is enough information in your report to generate an accurate score. If you do not meet the minimum criteria for getting a score, you may need to establish a credit history prior to applying for a mortgage.
