There's a lot to chew on here. I'm going to go with her credit profile is much to thin, perhaps young, as the only reason to be producing these kinds of swings. After carefully reading through each reply, I can can offer my data points.
I do have to ask the question, outside of revolving credit, what else do you have going on in her name? Revolving credit isn't the only game in town. For instance, I have dozens, of revolving credit lines in pristine condition, with holy hell credit lines, and utilizations scores ideal. I also have dozens of closed installment loans, ranging from multiple car loans paid off, to multiple, yes over a half dozen home refinances within a decade successfully paid on, to even energy efficient loans paid off, to personal loans paid off, to offroad loans paid off, to the tune of near 40+ accounts on record. Still holding the current home loan, becuase it makes sense at a low 2% rate. I'll get a random loan if it makes sense, for anything once in a while. Abuse the opportunity to carry multiple types of credit. If you aren't here, then you just don't know how powerful that is for producing a stable profile.
I've said this before, and I'm not afraid to say this again, holding a revolving line of credit, three or so cards, does not always make for a thick credit profile. I happen to think it's pretty thin. You have to invision what you think the lender sees. A FICO score is topical, it's not the substance that lies beneath. You can manipulate a FICO score. I know this first hand, as we've done it with multiple candidates. They were denied 3/4 of the time for loans, even with just shy of 800 FICO scores, because their credit profiles were young and thin, or questionable with questionable payment histories. Score swings varied wildly. Most people speculate, take educated guesses, and some people do. Careful who you take advice from. At the end of the day, we're all here to learn from the wonderful world of accumulated stories.
The armor of a well developed credit profile doesn't bend or break as easily as a of a thin profile. Score movement can be significantly less impactful. Sometimes, your score can even increase with adverse conditions, as I've experienced this a few times. I've posted a few of these examples.
Time, and routine, and girth of your credit profile. That will solidify the score and reduce the randomness.
I'm reminded by this snippet:
FICO scoring and these forums
As users of this forum have or will come to learn, there are certain observations that can be said about FICO scoring:
- we have come to know GENERALLY how FICO scoring works,
- we have come to know A LOT about how certain aspects of scoring works, BUT
- we have come to know that we do not know EXACTLY how all of FICO scoring works.
FICO's approach to performing credit scoring is proprietary, meaning that it is private. The folks at FICO knows how their scoring systems work. The rest of us take increasingly educated guesses at learning the finer points of those scoring models, and we come to forums like this to learn for ourselves how to understand, improve and manage our scores, and to help others to learn as well.
