Personal blog on early retirement, selling tradelines, and analytics projects. I write about what I learn as I am learning it.
681 is the score that gets you approved for most things — and makes you pay for it. Lenders see it as acceptable risk, so they’ll say yes. But you’re not in the range where they offer their best rates, and on something like a mortgage or a car loan, “not the best rate” can mean thousands of dollars in extra interest over the life of the loan.
So: is 681 a good credit score? Technically yes, depending on the model. Practically, there’s real money in pushing it higher.
The one I hear most often: “I keep a small balance on my card every month because my dad told me it helps your score.” It doesn’t. That particular credit myth has probably cost people hundreds of dollars in unnecessary interest. There are a handful of beliefs like that floating around — things that sound like they should be true but aren’t — and some of them are actively hurting the scores of people who follow them.
I’ve been selling tradelines and talking to buyers about their credit situations for a while now. The same credit myths come up constantly. Here are the ones worth actually understanding.
People who ask about tradelines usually hit the same wall once they understand the basics: “I already have a car loan — why would a credit card do more for my score?” It’s a fair question. Both are credit accounts, both show on your report, both require monthly payments. But the scoring models treat revolving and installment credit differently, and once you understand why, the mechanics of tradelines start to make a lot more sense.
The short version: revolving credit (credit cards) is where most of the scoring action happens, especially for utilization. Installment loans matter too — but for different reasons, through different levers.
The short answer is one requires a cash deposit and one doesn’t. Everything else — how it reports, how it builds credit, what the bureaus see — is essentially the same. The deposit is what “secured” means: you’re backing the credit line with your own money so the issuer isn’t taking a risk on you.
Buyers ask me versions of this question more than you’d think: “I financed my phone — does that count toward my credit?” The honest answer is: it depends entirely on whether your carrier reports to the credit bureaus, and many don’t. Which means a lot of people are paying $50 a month assuming they’re building credit history when nothing is actually hitting their report. I also cover How to build credit as a teenager in more detail in a separate post.
