TL;DR - I'm trying to build my shyt up but don't want to get another credit card to do it. Can I avoid that, or do I have to hold what I believe is an L in the short-term to get a W in the long-term?
Long version: Student loans continue to fukk me up
but it appears that due to paying on them, my credit score is fair, in the 690-695 range (it went down as bad as 520 or so at one point but I've managed to rebuild it). Point is, I'm trying to reach that higher peak.
From talking with my brother, he said the best (short-term) way to help your credit score basically boiled down to opening a line of credit somewhere/buying something major with a credit card and paying it off over time (he said the longer the payment process is drawn out, the better). I'm not sure on that as I feel like the quicker you wipe out a debt the better but I'm largely illiterate on the shyt as it is and furthermore I am
as fukk when it comes to the idea of getting another credit card (the one I do have was a dental/medical-focused one that I ended up getting because I needed a wisdom tooth extraction with the quickness and my dental insurance didn't kick in prior to the procedure), primarily because of how long it took me to rebuild my score back to what it was and -- keeping it a buck -- I'm not particularly used to having a "comfortable" level of income, although things took a considerable turn for the better in that regard.
But my brother said that I wouldn't be able to make any significant gains on my score unless I made some sort of purchase, for example, like getting a Macbook or something and paying it off over a year. The other prevalent method I heard was to get a card and designate it for certain purchases (gas, groceries) and pay that shyt off ASAP over and over.
Anyway, while I have my own reservations about the advice, when I consider the source -- he manages money/has more of it than most others in my family -- I'm taking it under advisement. What say y'all? How can I reach the
range of credit scores without putting myself at significant risk?
