I am currently building my credit to buy a home. I am making good progress. I was in the low 500’s In March of 2019 but now TU Fico 8 647, EX Fico 8 644, and EQ Fico 8 631. My Fico 8 scores are climbing and the Fico 2 scores were following along until something awful happened 😣. Recently I had a 30 day late payment added to all three credit reports. The late payment was inaccurate, I called the creditor and the accounts were corrected. TU and EQ removed but EX didn’t. Turns out they never got the update from the creditor. I disputed the info and after 3 days it was removed and the account was updated. My Fico 2 score before the late payment was 605 It dropped to 562 when the late was reported. Now that it has been removed it’s only 579. I am wondering why I didn’t get all my points back. Both mortgage scores for TU and EQ has exceeded what it was before the late. there has also been no other negative information reported. I am working hard paying collections and bringing my utilization down so I know nothing else would have affected it. I’m trying to understand why my score didn’t go back up to or pass the 605 it originally was. Please help
