Scoring your Credit - How's your FICO?

Before deciding on what terms lenders will offer you on a loan (which they base on the "risk" to them), they want to know two things about you: your ability to pay back the loan, and your willingness to pay back the loan. For the first, they look at your income-to-debt obligation ratio. For your willingness to pay back the loan, they consult your credit score.

In today's increasingly automated society, it should come as no surprise that when you apply for a mortgage, your ability to pay can be reduced to a single number. All the years you've been paying your mortgage, car payments, and credit card bills can be analyzed, sliced, diced, spindled and mutilated into a single indicator of whether you're likely to meet your future obligations.

All three of the major credit reporting agencies (Equifax, Experian and TransUnion) use a slightly different system to arrive at a score. The best known is called the FICO score, based on a model developed by Fair Isaac and Company (hence the name) and used by Experian. Equifax's model is called BEACON, while TransUnion uses EMPIRICA. While each of the models considers a range of data available in your credit report, the primary factors are:

Each of these, and other items, are assigned a value and a weight. The results are added up and distilled into a single number. FICO scores range from 300 to 850, with higher being better. Typical home buyers likely find their scores falling between 600 and 850.

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 indebtedness. Fifteen percent each is the time your open credit has been in use (ten year old accounts are good, six month old ones aren't as good) and types of credit available to you (installment loans such as student loans, car loans, etc. versus revolving and debit accounts like credit cards). Finally, five percent is pursuit of new credit -- credit scores requested.

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.
