Credit Report Question: Credit Cards

Since this is GQ, I was passing along first-hand information. This was from a quant jock who creates and runs the scoring models. My advice is to be careful about getting too many credit inquiries if you want to keep your score high.

Having no mortgage actually hurts your score. I subscribe to a credit monitoring service that lets me change my credit scenario to see how my actions would affect my score. One of the items was mortgage or no mortgage, or mortgage not current. Only the no mortgage and not current dropped my score.

At the time I did not have a mortgage but in the last 90 day I have acquired one and my score immediately went up about 20 points.

The logic behind it is that the more people who think you are credit worthy helps your score.

There isn’t actually much “logic” behind credit scores at all. The FICO model is a statistical one. If having a mortgage increases one’s score (and it certainly can) it is because people who have mortgages are less likely to declare bankruptcy or default on loans. The FICO score is designed to predict defaults. It’s logic is numerical. If people with mortgages are less likely to default on their debts, then they get higher scores.

As FICO told the Senate Committe on Banking, Housing, and Urban Affairs in 2003:

In SusanStoHelit’s example, the boss’s lack of a mortgage would not be a factor in the change in score because it was the same for both reports. The only change that she referred to in her question was an inquiry, although it is possible, as she has acknowledged, that an old account might have dropped off of the report.

Here is a FICO simulator for the curious.

FICO’s written statement, written to convince the Senate that FICO should not be compelled to disclose its scoring model because people already had access to plenty of information about credit scoring, has a pretty good summary of the publicly available information about credit scoring. It also has a good collection of reference materials.

Well, almost. My credit score was 825 last time I checked. The reason it wasn’t the full 850? Because I was carrying no balance on my credit cards. Or to put it another way, because I was too responsible!

We discussed that a bit here. And see, Understanding Your Credit Score (pdf) at 10:

(Emphasis added.)

Just wanted to add one other point of consideration concerning cancelling unused credit cards. I’ve read this in a couple of sources, but I believe one of them was a recent issue of Consumer Reports. Evidently, it used to be recommended that you cancel unused credit cards because it was more favourable for your credit score to have fewer lines of credit open. Now, however, experts are advising that cancelling those unused lines of credit could potentially damage your credit score because they could bring down the average length of history of your credit. I.e., if you have an old credit card that you never use and so you decide to cancel it, but most of your other lines of credit are fairly recent (say, a newer credit card and a new mortgage), you hurt yourself by taking the older card out of the equation because suddenly the average age of your credit lines has dropped.

Unfortunately, I didn’t learn that little tidbit until after I had gone and cancelled several unused store cards that I had initially opened to build a little credit history in this country. So now most of my credit looks pretty new. :smack:

But you said, “the #1 thing that impacts your credit score is the number of credit inquiries you get.” That’s just not true. Nobody disputes that inquiries will reduce one’s score. The questions are “how much?” “how many?” and “how long?” Fair Isaac says that both the number of inquiries, and the time since they were made, are part of a group of factors that, when aggregated, normally account for 10% of the important information affecting a FICO score. http://www.myfico.com/CreditEducation/WhatsInYourScore.aspx.

Furthermore, they say:

OTOH, they do say that

So avoiding large numbers of unrelated inquiries over long periods of time is definitely a good idea if you want your score to be as high as possible.

Re: inquiries hurting your score

I followed this kind of stuff for YEARS on the Creditnet [1] web site’s discussion forums.
The gist of what I learned is that THE HIGHER YOUR SCORES, the HIGHER THE IMPACT OF MORE INQUIRIES. Conversely, THE LOWER YOUR SCORES, the LOWER THE IMPACT OF MORE INQUIRIES.
Basically, if your credit is the suck already (under 600), more inquiries really won’t hurt you much at all.
If your credit is really good (over 750) inquiries have been observed to damage scores by 30 points.
I would submit my personal opinion that the scoring model is very accurate at detecting complete deadbeats, good at detecting people who pay the vast majority of their bills on time and carry reasonable % used on their cards, and much less useful in determining the difference between a highly responsible borrower and a highly, highly responsible borrower.
I realize the system demonstrably WORKS even at higher scores, but it seems like it makes a lot more sense for individuals I know that I see in the 500-680 range than it does at either end of the scale.

I should have mentioned my theory on your friend in my last post.
I believe that what he said is wholly correct, assuming that the “your” and “you” in that statement was you, nivlac, and he knew or expected that you would already have a good credit score and generally be on sound financial footing.
Even though some of us challenge your beliefs on this matter, your associate may have been wholly accurate with what he said.

ARGH. The cite [1] from my post two posts up from this one should have been:

Fair Isaac is now promoting its FICO NextGen score, btw, which:

  1. Reduces the requirments for getting a score. (Some people have no score reported because they have an insufficient credit record).
  2. Extends the buffer period in which inquiries are not counted from 30 to 45 days.
  3. No longer considers collection accounts with balances under $100.
  4. Does not penalize consumers for tradelines from consumer finance companies.

So far, few lenders are using the NextGen scores. http://www.fairisaac.com/NR/rdonlyres/C77AF033-FFF1-4153-8FF0-AABEB1CEC16C/0/VP262_HowandWhy_AR.pdf.
