Q: They paid off the mortgage. Then the credit score fell. Can that be right?

Dear Liz: My wife and I recently paid off our mortgage. We have no other debt. Soon after, I received a message from Experian that my FICO score, which has been perfect for quite a while, was reduced by 31 points. What justifies such action, and what do I need to do to bring up my score?

Answer: Credit scores were never intended to be a measure of anyone’s financial health. Instead, they were created to help lenders gauge the risk that an applicant would default on a loan or credit card debt.

Having a mix of types of credit, including installment loans (such as a mortgage) and revolving accounts (such as credit cards), generally helps your credit score. Because the mortgage was your only installment loan, that could have led to a larger-than-normal effect on your scores.

If your previous score was “perfect,” or 850 on the FICO scale, then there’s nothing you need to do. Once your scores are over about 760, you’re getting the best rates and terms, and there’s typically no other benefit to shoot for, other than bragging rights.

Q&A: The bottom line on getting your credit scores in better shape

Dear Liz: I want to write a letter of explanation to be included on my credit reports to explain a negative posting. How much impact will the letter have on my credit scores?

Answer: Credit scoring formulas can’t read, so letters of explanation won’t help your scores.

You do have a federal right to demand the credit bureaus include your explanation, which is also known as a consumer statement, in your credit reports. Theoretically, the statement could help a lender understand why you have the negative mark — but only if a human being actually examines your credit report and uses the information in evaluating your creditworthiness.

Because lending is largely automated, however, there’s no guarantee your statement will be read, let alone factored into a lending decision. Many of the other details of your credit report are converted to standardized codes used to calculate credit scores, but not consumer statements.

If the negative information in your reports isn’t accurate, you can dispute it with the credit bureaus. If the information is accurate, you can work to offset the effect on your scores.

Paying your credit accounts on time, all the time, will help rebuild credit. So will using less than 10% of your limits on credit cards.

If you don’t have a credit card, consider getting a secured card — where the credit limit typically is equal to the amount you deposit with the issuing bank. Credit builder loans, available at many credit unions, also can help add positive information to your credit reports.

Don’t close accounts, because that could hurt your scores and won’t get rid of any associated negative information.

People with only a few credit accounts also can help their scores by being added as an authorized user to a responsible person’s credit card. The responsible person doesn’t need to grant access to the actual card. Before taking this step, though, ask the credit card issuer whether authorized user information will be imported to your credit reports because issuers’ policies vary.

Q&A: Helping a son with horrible credit scores

Dear Liz: My 33-year-old son has horrible credit scores. If I added his name to my credit card, would it have a positive effect on his score without any negative ramifications to mine? Could any of his creditors come after me?

Answer: Adding someone to your credit card as an authorized user can have a positive effect on their credit scores without negatively affecting your own or obligating you to pay their other debts. You would be responsible for any debt your authorized user incurred on the card.

In your son’s case, though, being added as an authorized user probably won’t help much.

When someone has fallen behind on their bills, the effect on their scores depends on three main factors: recency (how recently did a late payment occur?), severity (how far behind are they — 30 days, 60 days, 90 days or more?) and frequency (how many accounts have late payments?).

One skipped payment can knock 100 points or more off good scores but won’t result in “horrible” credit. Truly bad credit typically requires someone to be well behind on a number of accounts in the recent past. The fact that you’re worried about his creditors indicates that he may not have resolved his financial problems enough to start rebuilding his credit.

What he should do now depends on his circumstances.

If he still has a job, he may be able to arrange a payment plan or settle debts with collectors. If his income has dropped or he’s otherwise unable to pay, he may need to consider bankruptcy.

Once his past debts are resolved — either paid, settled or legally erased — he can take steps to improve his credit, one of which could include being added to your card. A credit builder loan, offered by many credit unions, also could help, as could a secured credit card, which requires a deposit.

It’s crucial that he be able to make all his payments on time, however. If he falls behind again, he’ll offset any progress that’s been made.

Q&A: I get different credit scores from my bank and card companies. What gives?

Dear Liz: I have three financial providers that supply regular, free credit scores: my bank and two credit card issuers. My credit score from the bank is always a “perfect score” while the two card companies are consistently 17 points lower, both exactly the same for two years now. I always pay off most or all of the outstanding balance on time or early. Any clue as to why there is this consistent difference?

Answer: The companies probably are using different credit scoring formulas or different credit bureaus, or both.

You don’t have one credit score. You have many. FICO is the dominant scoring formula, but lenders also use VantageScores and the credit bureaus sometimes provide their own, proprietary scores.

The formulas have been updated over the years. The FICO 8 is the most commonly used score, but the FICO 9 is the latest version and FICO 10 will be introduced this summer. Some scoring formulas are modified to suit different industries, such as auto lending or credit cards, plus each score is calculated from data at one of the three credit bureaus.

So one institution may provide its customers a FICO Score 9 from Experian, another might offer a FICO 8 Bankcard score from Equifax and a third might give you a VantageScore 3.0 from TransUnion. Even if all three were using the same type of score, they probably would use different credit bureaus, or vice versa. To make things even more confusing, your credit scores are constantly changing as your credit bureau information changes.

Furthermore, you typically can’t predict which score or scores a lender will use to evaluate your application for credit. Rather than worry about which number is “right” — they all are — use the free scores as a general indicator of your credit health.
