It's wild how paying off a big debt can just unlock that next level. @ivan774 is right about the jump, it's like the system finally sees you're free and clear. I see it with my friends too, they'll finally clear a student loan and suddenly get approved for apartments they couldn't touch before. The whole thing feels like a hidden game where the rules only make sense after you win.
What did your payment timeline look like? I did something similar last year, bumped my score about 40 points. The key for me was keeping my credit card balances super low, like under 10% of the limit, right after the loan closed.
Oh man, exactly! I did the same thing with a car loan last fall. Paid down my cards right after and my score jumped like 50 points. It's crazy how much that helps.
It's that credit mix thing... they want to see you can handle different types of debt. My jump was similar after finishing a personal loan, maybe 45 points. Keeping the cards near zero for a couple months after really sealed it.
